GS Paper: GS3

  • Fake News: Addition of The Provision In Intermediary Guidelines

    Fake News

    Central Idea

    • The addition of the fake news provision in the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021 (Intermediary Guidelines) must be seen in the context of protecting fundamental rights while combatting fake news. The recent addition by the central government clearly militates against settled law and the Constitution.

    What is mean by Fake news?

    • Fake news refers to intentionally fabricated or misleading information presented as if it were real news. It can be spread through traditional media sources like newspapers or television, but it is more commonly associated with social media platforms and other online sources.
    • Fake news can range from completely made-up stories to misleading headlines and selectively edited or out-of-context information designed to deceive readers.
    • It is often used for political purposes, to manipulate public opinion or to spread misinformation about individuals, organizations or events.

    Fake News

    Existing Provisions to Combat Fake News

    • Intermediary Guidelines of 2021: The most preferred democratic process to combat the threats and impact of fake news on a polity would be through Parliament-enacted laws. India opted for the speedier alternative of an addition to the Intermediary Guidelines of 2021 (as amended), through Rule 3(1)(v).
    • Can not disseminate misleading content: Under this rule, intermediaries including social media platforms have to ensure that users do not disseminate content that deceives or misleads on the origin or knowingly and intentionally communicates any information which is patently false or misleading in nature but may reasonably be perceived as a fact.

    Remedies Available

    • Complaints and grievance: Any complaints from users, government, or court have to be actioned by the grievance officer of an intermediary, including social media platforms, within 15 days. This timeframe for actioning a complaint for complaints of false or misleading news is reduced to 72 hours.
    • Resolution: The next step for resolution is provided through the Grievance Appellate Committees, which the government recently announced appointments for.
    • Other actions: These remedies are independent of and in addition to the remedies available in law for a government agency to seek takedowns or blocking, as per due process or for courts to decide thereon.

    Fake News

    Critique of the Addition

    • Provisions already exists: The recent addition of a separate category for restraint on dissemination by users of content in respect of any business of the Central Government is unwarranted as provisions already exist. The restraint is on users and not intermediaries, as misconceived by many. The onus on intermediaries is only of reasonable effort.
    • No transparency: With merely a central government-authorised fact check unit saying so, content could be classified as fake, false or misleading and a takedown and action necessitated, without even a semblance of due process.
    • No legitimacy: In the present instance, there is an absolute absence of legitimate aim for this additional restriction on users and an abject lack of procedures that would assure due process.

    Reaffirming the Need for Legitimacy

    • The recent addition clearly militates against settled law and the Constitution: The Supreme Court in Puttaswamy judgment reaffirmed the need for legitimacy, supported by parliament enacted laws, which are proportionate to meet the test of constitutionality.
    • Media One case: Supreme Court’s recent judgment in the Media One case (Madhyamam Broadcasting Limited v. Union of India, April 5, 2023) reiterates that any law or regulation inconsistent with fundamental rights is void. This judgment also reaffirms the four principles that will decide the constitutionality of a law or regulation: (i) unreasonableness or irrationality; (ii) illegality; and (iii) procedural impropriety.

    Fake News

    Some of the dangers of fake news

    • Inciting communal violence: In India, fake news has been known to incite communal violence. For instance, the spread of fake news on social media was one of the factors behind the Muzaffarnagar riots of 2013.
    • Undermining public trust: Fake news can undermine public trust in institutions and the media. This can have serious consequences for democracy and social cohesion.
    • Impact on health: Fake news about health issues can have serious consequences. For example, during the COVID-19 pandemic, fake news about remedies and cures for the disease led to people consuming dangerous substances.
    • Misinformation during elections: Fake news can also be used to spread misinformation during elections, which can influence voters and distort the democratic process.
    • Economic harm: Fake news can cause economic harm by spreading false information about businesses, leading to loss of investor confidence and financial losses.
    • Spreading rumors: Fake news can also be used to spread rumors about individuals, which can have serious consequences, such as the recent case of fake news leading to the lynching of two men in Assam.

    Conclusion

    • The recent addition is unsustainable and unwarranted as provisions already exist. The fight should be for the protection of fundamental rights that are essential to our very existence.

  • Fishing Industry: India and Sri Lanka Needs a Boost

    Central Idea

    • The neglect of the fishing industry by India and Sri Lanka has resulted in an ongoing dispute over fishing rights in the Palk Strait. Developing the fishing industry could help resolve the conflict and boost the economies of both countries.

    Fishing Industry

    What is Blue Economy?

    • Origin of the concept: Gunter Pauli’s book, “The Blue Economy: 10 years, 100 innovations, 100 million jobs” (2010) brought the Blue Economy concept into prominence.
    • A project to find best nature inspired and sustainable technologies: Blue Economy began as a project to find 100 of the best nature-inspired technologies that could affect the economies of the world. While sustainably providing basic human needs potable water, food, jobs, and habitable shelter.
    • Inclusive approach and objective: This is envisaged as the integration of Ocean Economy development with the principles of social inclusion, environmental sustainability and innovative, dynamic business models
    • Environment friendly maritime infrastructure: It is creation of environment-friendly infrastructure in ocean, because larger cargo consignments can move directly from the mothership to the hinterland through inland waterways, obviating the need for trucks or railways

    Indo-Sri Lankan dispute over fishing rights in Palk Strait

    • Maritime boundary agreement: The maritime boundary agreements signed in 1974 and 1976 allowed fishermen of both nations to fish in each other’s waters as they traditionally did.
    • Absence of physical demarcation: Lack of physical demarcation of maritime boundaries resulted in Indian fishermen encroaching into Sri Lankan waters during the civil war.
    • Rising conflicts: The Sri Lankan fishing community sought to reclaim their rights after the end of hostilities, leading to conflict with Indian fishers. Sri Lankan Navy’s intervention has resulted in arrests and even fatal shootings of Indian fishermen.

    Neglect of the fishing industry by India and Sri Lanka

    • India’s marine fishery: India’s marine fishery has been dominated by the artisanal sector, which can afford only small sailboats or canoes to fish for subsistence.
    • Lack of investment: India’s fisheries are being transformed into a commercial enterprise, but lack of investment in a deepwater fleet results in most fishing taking place in coastal waters, leading to competition with neighboring countries.
    • Underexploited resources: Rich resources in India’s Exclusive Economic Zone remain underexploited, with much of the catch from India’s fishing grounds taken away by better-equipped fishing fleets of other Indo-Pacific countries indulging in illegal, unregulated, and unreported fishing.
    • Growing tensions: Neglect of the fishing industry has resulted in dwindling fish stocks, rising fuel costs, and growing tensions between India and Sri Lanka.

    Development of the fishing industry

    • China: China has mobilized its fishing industry to meet rising demand for protein in the Chinese diet and is now a fishery superpower.
    • India: India needs to invest in a deepwater fleet to exploit rich fishing grounds in its Exclusive Economic Zone and compete with other countries in the Indo-Pacific region.
    • India must focus on modernisation: India should focus on mechanization and modernization of fishing vessels, developing deep-water fishing fleets, building a DWF fleet around the mother ship concept, and developing modern fishing harbours.

    PM Matsya Sampada Yojana

    • PM Matsya Sampada Yojana is a scheme launched by the Government of India in 2020, with the aim of boosting the fisheries sector in the country. The scheme has a total outlay of Rs. 20,050 crores and is implemented over a period of five years from 2020-21 to 2024-25. The scheme is focused on four key areas of intervention, which include:
    1. Development of infrastructure and modernization of the fisheries sector: This involves the creation of new fishing harbours, fish landing centres, cold chain facilities, and other related infrastructure.
    2. Fisheries management and regulatory framework: This involves strengthening the regulatory framework for fisheries and aquaculture, promoting sustainable fishing practices, and conserving marine biodiversity.
    3. Fisheries post-harvest operations and value chain: This involves promoting the processing and value addition of fish and fishery products, and improving market access for fishermen and fish farmers.
    4. Aquaculture development: This involves promoting the development of inland fisheries and aquaculture, including the creation of new fish farms, and supporting the adoption of modern technologies for fish farming.

    Conclusion

    • Neglect of the fishing industry by India and Sri Lanka has resulted in an ongoing dispute over fishing rights in the Palk Strait. Developing the fishing industry could help resolve the conflict and boost the economies of both countries. The government’s Pradhan Mantri Matsya Sampada Yojana could be used to form an Indo-Sri Lankan Fishing Corporation to provide a huge boost to the fishing industries of both nations and remove an unwanted irritant in bilateral relations.

    Mains Question

    Q. It is said that fishing industry has been overly neglected by India and Sri Lanka. Development of the fishing industry is crucial to boost the economy for both the countries. Discuss.

  • Artificial Intelligence (AI) for Legislative Procedures

    AI

    Central Idea

    • Artificial Intelligence (AI) has gained worldwide attention, and many mature democracies are using it for better legislative procedures. In India, AI can be used to assist parliamentarians in preparing responses for legislators, enhancing research quality, and obtaining information about any Bill, legislative drafting, amendments, interventions, and more. However, before AI can work in India, there is a need to codify the country’s laws, which are opaque, complex, and face a huge translation gap between law-making, law-implementing, and law-interpreting organizations.

    What is Artificial Intelligence?

    • AI is a constellation of technologies that enable machines to act with higher levels of intelligence and emulate the human capabilities of sense, comprehend and act.
    • The natural language processing and inference engines can enable AI systems to analyze and understand the information collected.
    • An AI system can also take action through technologies such as expert systems and inference engines or undertake actions in the physical world.
    • These human-like capabilities are augmented by the ability to learn from experience and keep adapting over time.
    • AI systems are finding ever-wider application to supplement these capabilities across various sectors

    Need to Codify Laws

    • Current laws are complex and opaque: Current laws in India pose many challenges, such as their complexity, opaqueness, and lack of a single source of truth.
    • The India Code portal does not provide complete information: The India Code portal is not enough to provide complete information about parent Acts, subordinate legislation, and amendment notifications.
    • AI can be used to provide comprehensive information: There is a need to make laws machine-consumable with a central law engine, which can be a single source of truth for all acts, subordinate pieces of legislation, gazettes, compliances, and regulations. AI can use this engine to provide information on applicable acts and compliances for entrepreneurs or recommend eligible welfare schemes for citizens.

    Assisting Legislators

    • Potential of AI for legislators: AI can help Indian parliamentarians manage constituencies with a huge population by analysing citizens’ grievances and social media responses, flagging issues that need immediate attention and assisting in seeking citizen inputs for public consultation of laws and preparing a manifesto.
    • AI-powered assistance: Many Parliaments worldwide are now experimenting with AI-powered assistants.
    • For instance:
    • Netherlands’s Speech2Write system: The Speech2Write system in the Netherlands House of Representatives, which converts voice to text and translates voice into written reports.
    • AI tools Japan: Japan’s AI tool assists in preparing responses for its legislature and helps in selecting relevant highlights in parliamentary debates.
    • Brazil: Brazil has developed an AI system called Ulysses, which supports transparency and citizen participation.
    • NeVA portal India: India is also innovating and working towards making parliamentary activities digital through the ‘One Nation, One Application’ and the National e-Vidhan (NeVA) portal.

    Simulating Potential Effects of Laws

    • Dataset modelling: AI can simulate the potential effects of laws by modelling various datasets such as the Census, data on household consumption, taxpayers, beneficiaries from various schemes, and public infrastructure.
    • Flag outdated laws: In that case, AI can uncover potential outcomes of a policy and flag outdated laws that require amendment.
    • For example: During the COVID-19 pandemic, ‘The Epidemic Diseases Act, 1897’ failed to address the situation when the virus overwhelmed the country. Several provisions in the Indian Penal Code (IPC) are controversial and redundant, such as Article 309 (attempted suicide) of the IPC continues to be a criminal offense. Many criminal legislation pieces enacted more than 100 years ago are of hardly any use today.

    Conclusion

    • The COVID-19 pandemic has given a strong thrust to the Digital India initiative, and a digitization of services needs to be kept up in the field of law, policy-making, and parliamentary activities, harnessing the power of AI. However, the use of AI must be encouraged in an open, transparent, and citizen-friendly manner, as AI is a means to an end, not an end in itself. Therefore, it is necessary to address the current challenges faced by India’s laws before AI can be effectively used to assist parliamentarians in their legislative duties.

    Mains Question

    Q. Artificial Intelligence (AI) has gained worldwide attention, and many mature democracies are using it for better legislative procedures. In this light evaluate the potential of AI in assisting Indian parliamentarians.

  • India’s Space Industry: Enormous Potential

    Central Idea

    • India needs an enabling policy and regulatory environment to tap into the potential of the Second Space Age and its rapidly growing space economy.

    What is mean by the Second Space Age?

    • Commercialization: The Second Space Age refers to the recent era of increased commercialization and private sector involvement in space exploration, which began in the early 2000s.
    • Emergence of private space companies: This period has been marked by the emergence of private space companies like SpaceX, Blue Origin, and Virgin Galactic, who are investing heavily in space technology and infrastructure.
    • Today’s space domain has many more actors once dominated by US and USSR: Compared to the First Space Age dominated by the US and the USSR, today’s space domain has many more actors, with a majority being private companies. Private companies account for 90% of global space launches since 2020, and India is no exception
    • Increasing involvement of non-spacefaring nations: The Second Space Age is also characterized by the increasing involvement of non-spacefaring nations in space exploration and the development of technologies that enable greater access to space for both commercial and scientific purposes.
    • Exploration: The hope is that this new era will lead to breakthroughs in areas like space tourism, asteroid mining, and Mars colonization, among others.

    India’s Space Journey

    • India’s journey in space began modestly in the 1960s.
    • Societal objectives: Over the decades, the Indian Space Research Organisation (ISRO) prioritized societal objectives and benefits, such as developing satellite technology for mass communication, remote sensing for weather forecasting, resource mapping of forests, agricultural yields, groundwater and watersheds, fisheries and urban management, and satellite-aided navigation.
    • Enhanced launch capabilities: ISRO also developed satellite launch capabilities, beginning with the SLV-1 in the 1980s, followed by the PSLV series, which has become its workhorse with over 50 successful launches.

    Facts for prelims

    India’s Space Potential

    • Economy and employment: India’s space economy, estimated at $9.6 billion in 2020, is expected to be $13 billion by 2025. However, with an enabling policy and regulatory environment, the Indian space industry could exceed $60 billion by 2030, directly creating more than two lakh jobs.
    • Downstream activities: Downstream activities such as satellite services and associated ground segment are dominant, accounting for over 70% of India’s space economy.
    • Media and entertainment segment: Media and entertainment account for 26% of India’s space economy, with consumer and retail services accounting for another 21%.

    The Growing Role of the Private Sector

    • Increasing space start ups: The Indian private sector is responding to the demands of the Second Space Age, with over 100 space start-ups today. From less than $3 million in 2018, investment in the sector has doubled in 2019 and crossed $65 million in 2021.
    • Potential of multiplier effect on economy: The sector is poised for take-off, as a transformative growth multiplier like the IT industry did for the national economy in the 1990s.

    Way ahead: Creating an Enabling Environment

    • ISRO needs to focus on research and collaborate with the Indian private sector, which has different needs and demands.
    • To create an enabling environment for the private sector, India needs a space activity act that provides legal grounding, sets up a regulatory authority, and enables venture capital funding into the Indian space start-up industry.
    • Although a series of policy papers have been circulated in recent years, legislation is needed to provide legal backing and create an enabling environment for private sector growth.

    Conclusion

    • India’s space industry has enormous potential, but realizing it requires an enabling policy and regulatory environment that encourages private sector growth. With a space activity act that provides legal backing, sets up a regulatory authority, and enables venture capital funding, India can take advantage of the Second Space Age and become a major player in the global space economy.

  • CSIR scientists identify Rare-Earth deposits in AP

    rare

    Scientists at the National Geophysical Research Institute (NGRI) in Hyderabad have discovered the presence of rare-earth elements (REEs) in Anantapur district, Andhra Pradesh.

    What are Rare-Earth Elements?

    • Rare-earth elements (REEs) are a group of 17 elements, including lanthanum, cerium, praseodymium, neodymium, yttrium, hafnium, tantalum, niobium, zirconium, and scandium.
    • These elements are widely used in modern electronics, such as smartphones, computers, jet aircraft, and other products, due to their unique magnetic, optical, and catalytic properties.
    • These elements are crucial components in various electronic devices and have industrial applications in sectors like imaging, aerospace, and defense.

    SHORE Project and discovery of REEs

    • The discovery was part of a study funded by the Council of Scientific and Industrial Research (CSIR) under a project called ‘Shallow subsurface imaging Of India for Resource Exploration’ (SHORE).
    • NGRI scientists found enriched quantities of REEs in “whole rock analyses”.
    • Drilling for at least a kilometer deep will help ascertain the consistency of the elements’ presence underground.

    Significance of the discovery

    • The discovery of REEs in Anantapur district is significant as these elements are in high demand worldwide, and their supply is limited.
    • REEs have become a subject of geopolitical concern due to their increasing demand and limited supply.
    • China is currently the world’s largest producer and exporter of rare-earth elements (REEs), accounting for more than 80% of global production.
    • The country has significant reserves of REEs and has invested heavily in mining and processing infrastructure.

  • LIGO-India: India’s Node in Global Universe Probe

    ligo

    India has given the final approval to build its biggest scientific facility, Laser Interferometer Gravitational-Wave Observatory (LIGO), in the Hingoli district of Maharashtra. The facility will join the global project to detect and study gravitational waves.

    Gravitation and General Theory of Relativity

    • Newton’s law of gravitation, proposed by Sir Isaac Newton in the 17th century, explains that the force that makes an object fall to the ground is also responsible for making heavenly bodies go around in their orbits.
    • However, the theory did not explain the existence of an attractive force between any two bodies or the instantaneous propagation of the gravitational force over large distances.
    • In 1915, Albert Einstein proposed the General Theory of Relativity, which altered our understanding of gravitation. Einstein proposed that space-time interacted with matter, was influenced by it, and in turn, and influenced events.
    • The curvature in space-time produced by matter was the reason other smaller bodies in the vicinity felt the gravitational pull.
    • General Relativity also predicted that moving objects would generate gravitational waves in space-time.

    What is LIGO?

    What is it?

    		 Laser Interferometer Gravitational-Wave Observatory (LIGO)
    Purpose Detect and study gravitational waves
    Cause Ripples in spacetime caused by violent and energetic events in the universe
    Location Livingston, Louisiana and Hanford, Washington
    Detector Michelson interferometer

    About LIGO-India

    • LIGO-India will be the fifth node of this international network of gravitational wave observatories, and possibly the last.
    • The instrument is so sensitive that it can easily get influenced by events like earthquakes, landslides, or even the movement of trucks, and produce a false reading.
    • That is why multiple observatories are needed to revalidate the signals.
    • India’s involvement in LIGO is crucial to demonstrating its intent and capability to pull-off complex science projects independently.

    Significance

    • The detection and study of gravitational waves could help in understanding the universe’s structure, the origin of the universe, and the functioning of black holes.
    • The LIGO project also has huge spin-off benefits for India’s science and technology sector.

     

  • Physicists discover new Uranium Isotope

    uranium

    Physicists in Japan have discovered a new isotope of uranium, with atomic number 92 and mass number 241.

    Uranium

    • Uranium is a naturally occurring chemical element with the symbol U and atomic number 92.
    • It is a heavy metal that is radioactive and found in small quantities in rocks and soils worldwide.
    • Uranium has several isotopes, which are atoms that have the same number of protons but different numbers of neutrons.

    Isotopes of Uranium

    The most common isotopes of uranium are uranium-238 and uranium-235.

    1. Uranium-238: It is the most abundant isotope of uranium, accounting for over 99% of natural uranium. It has 92 protons and 146 neutrons in its nucleus. It is not fissile, which means it cannot sustain a nuclear chain reaction. However, it is fertile, which means it can absorb neutrons and undergo radioactive decay to produce other isotopes such as plutonium-239, which is fissile.
    2. Uranium-235: It is the second most abundant isotope of uranium, accounting for less than 1% of natural uranium. It has 92 protons and 143 neutrons in its nucleus. Unlike uranium-238, it is fissile, which means it can sustain a nuclear chain reaction. It is used as fuel in nuclear reactors and as the primary material for nuclear weapons.

    How are isotopes created?

    • Isotopes can be created through natural processes or artificial processes in a laboratory.
    • Isotopes are created through natural processes such as radioactive decay, cosmic ray interactions, and nuclear fusion reactions in stars.
    • For example, carbon-14 is created in the Earth’s upper atmosphere when cosmic rays interact with nitrogen atoms.
    • Isotopes can also be created artificially through nuclear reactions.
    • This involves bombarding atoms with particles such as protons, neutrons, or alpha particles, which can change the number of protons and/or neutrons in the nucleus.

    How uranium-241 was found?

    • To find uranium-241, the researchers accelerated uranium-238 nuclei into plutonium-198 nuclei using the KEK Isotope Separation System (KISS).
    • In a process called multinucleon transfer, the two isotopes exchanged protons and neutrons, resulting in nuclear fragments with different isotopes.
    • The researchers identified uranium-241 and measured the mass of its nucleus using time-of-flight mass spectrometry.
    • Theoretical calculations suggest that uranium-241 could have a half-life of 40 minutes.

    Significance of the discovery

    • The discovery is significant because it refines our understanding of nuclear physics, particularly the shapes of large nuclei of heavy elements and how often they occur.
    • This information helps physicists to design models for nuclear power plants and exploding stars.

    Also, what are Magic numbers?

    • There is a particular interest in ‘magic number’ nuclei, which contain a certain number of protons or neutrons that result in a highly stable nucleus.
    • Lead (82 protons) is the heaviest known ‘magic’ nucleus, and physicists have been trying to find the next element with magic numbers.
    • The researchers hope to extend their systematic mass measurements towards many neutron-rich isotopes, at least to neutron number 152, where a new ‘magic number’ is expected.

    Conclusion

    • The discovery of the new neutron-rich uranium isotope is a major breakthrough in nuclear physics, as it provides essential information for understanding the behavior of heavy elements.
    • The researchers’ aim to extend their measurements to other neutron-rich isotopes reflects their commitment to exploring the frontiers of nuclear science and to improve our understanding of the universe.
    • Discovering new magic number nuclei through these measurements could have practical applications in designing safer and more efficient nuclear power plants and understanding the properties of exploding stars.

     

  • The Statistical Genius: C. R. Rao

    rao

    Central idea: Indian-American statistician Calyampudi Radhakrishna Rao has been awarded the 2023 International Prize in Statistics, which is considered the Nobel Prize for statistics.  He is 102 YO.

    Who is C. R. Rao?

    • R. Rao, is an Indian-American mathematician and statistician.
    • He is currently professor emeritus at Pennsylvania State University and Research Professor at the University at Buffalo.
    • Rao has been honoured by numerous colloquia, honorary degrees, and festschrifts and was awarded the US National Medal of Science in 2002.
    • The American Statistical Association has described him as “a living legend whose work has influenced not just statistics, but has had far reaching implications for fields as varied as economics, genetics, anthropology, geology, national planning, demography, biometry, and medicine.”
    • The Times of India listed Rao as one of the top 10 Indian scientists of all time.

    Rao’s Groundbreaking Paper

    • The research paper, “Information and accuracy attainable in the estimation of statistical parameters,” was published in 1945 in the Bulletin of the Calcutta Mathematical Society.
    • The paper provided a lower limit on the variance of an unbiased estimate for a finite sample, which has since become a cornerstone of mathematical statistics.

    Key outcomes of his research

    Rao’s 1945 paper has three outcomes-

    1. Cramer-Rao inequality: It provides a lower limit on the variance of an unbiased estimate for a finite sample.
    2. Rao-Blackwell Theorem: It provides a method to improve an estimate to an optimal estimate.
    3. Information geometry: It is a new interdisciplinary area called “information geometry,” which integrated principles from differential geometry into statistics, including the concepts of metric, distance, and measure.

    SpaceX Falcon 9 rocket successfully launched carrying a new NASA device named Tropospheric Emissions Monitoring of Pollution (TEMPO) designed to monitor air pollutants and their emission sources across North America from space more comprehensively than ever before.

    What is TEMPO?

    • TEMPO is an instrument developed by NASA, which will enable scientists to monitor air pollutants and their emission sources from space, down to the neighbourhood level.
    • This instrument will measure pollution and air quality across greater North America on an hourly basis during the daytime.

    TEMPO’s special features

    • TEMPO is unique because it will be hosted on an Intelsat communications satellite in geostationary orbit, about 22,236 miles (35,786 km) above the equator.
    • This will allow the instrument to match the rotation of the Earth, meaning it will stay over the same location (North America) at all times.
    • It will be able to measure atmospheric pollution down to a spatial resolution of 4 square miles (10 square km), or neighbourhood level.

    Applications of TEMPO

    • TEMPO will have multiple applications from measuring levels of various pollutants to providing air quality forecasts and helping the development of emission-control strategies.
    • The data will be used by the US Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), and other agencies responsible for tackling atmospheric pollution.

    Importance of the mission

    • According to the American Lung Association, more than 40% of the US population, 137 million people, live in places with unhealthy levels of particle pollution or ozone, and air pollution is blamed for some 60,000 premature deaths a year.
    • TEMPO will track pollutants like nitrogen dioxide, produced from the combustion of fossil fuels, formaldehyde, and ozone.
