These traces provided an unexpected window into what low-emissions world could look like, thus providing a means for identifying effective environmental policies. While many countries in the last few decades have implemented environmental policies to reduce human health risk from air pollution by controlling emissions, the impacts of those policies have not always been clear. The global lockdowns in response to COVID-19 represent a well-observed “scenario-of-opportunity” that allows us to assess how atmospheric emission and composition responds to reduced human activity. COVID-19 lockdowns effectively showed how reducing NOx emissions affects the global atmosphere. Its identifying signature shows up as in the atmosphere’s altered ability to produce harmful ozone pollution and ozone’s reduced influence on Earth’s heat balance that affects climate. These effects are not uniform across the world and depend on the location and season of the emission reductions.The results of this research indicate that in order to design effective environmental policies which benefit both air quality and climate, decision-makers need to carefully consider the complex relationships between emissions and atmospheric composition. || ", "hits": 40 }, { "id": 13712, "url": "https://svs.gsfc.nasa.gov/13712/", "result_type": "Produced Video", "release_date": "2020-11-30T11:00:00-05:00", "title": "Landsat 9: Continuing the Legacy series", "description": "Five decades ago, NASA and the US Geological Society launched a satellite to monitor Earth’s land from space.

The first Landsat — originally known as the Earth Resources Technology Satellite, or ERTS — rocketed into space in 1972. Since then, there have been eight Landsats and we’re preparing to launch number nine.The Landsat legacy stretches far and wide. Using visible and infrared light, Landsat helps track the health of crops, shows ocean pollution, and tracks coral reefs, icebergs and more. Thanks to sensor that can record wavelengths beyond what we can see with our eyes, Landsat can record vital information about Earth's surface.Narrated by the actor Marc Evan Jackson, who played a Landsat scientist in the movie Kong: Skull Island (2017), this series of videos tells the story of Landsat 9.

One notable exception is in Lima, Peru, showing a 69% decrease. The large decrease may partly be associated with natural variations in weather that can, for instance, disperse air pollution more quickly.

A total column amount of 1 means that the total amount of carbon monoxide in a vertical column from the top of the atmosphere to the surface is 10^18 molecules per square centimeter.In these maps, yellow areas have little or no carbon monoxide, while progressively higher concentrations are shown in orange, red, and dark red. || ", "hits": 37 }, { "id": 13193, "url": "https://svs.gsfc.nasa.gov/13193/", "result_type": "Produced Video", "release_date": "2019-04-23T16:00:00-04:00", "title": "Space Down to Earth", "description": "Space Down to Earth (1970) || Space_Down_to_Earth.png (953x682) [318.9 KB] || Space_Down_to_Earth_print.jpg (1024x732) [49.2 KB] || Space_Down_to_Earth_searchweb.png (320x180) [55.7 KB] || Space_Down_to_Earth_thm.png (80x40) [5.1 KB] || Space_Down_to_Earth_1970_1.mov (1280x720) [9.5 GB] || Space_Down_to_Earth_1970_1.mp4 (1920x1080) [449.6 MB] || Space_Down_to_Earth_1970_1.webm (1280x720) [211.9 MB] || GSFC_20190423_m13193_Space_Down_to_Earth_1970.en_US.srt [12.0 KB] || GSFC_20190423_m13193_Space_Down_to_Earth_1970.en_US.vtt [12.0 KB] || ", "hits": 46 }, { "id": 4676, "url": "https://svs.gsfc.nasa.gov/4676/", "result_type": "Visualization", "release_date": "2019-02-12T00:00:00-05:00", "title": "Sulfur Dioxide 2018 Update", "description": "China || so2_china_4K.0000_print.jpg (1024x576) [176.6 KB] || so2_china_4K.0000_thm.png (80x40) [6.0 KB] || so2_china_4K.0000_searchweb.png (320x180) [81.6 KB] || so2_china_4K.0000_web.png (320x180) [81.6 KB] || china (3840x2160) [64.0 KB] || so2_china_4K_2160p30.webm (3840x2160) [4.1 MB] || so2_china_4K_2160p30.mp4 (3840x2160) [113.0 MB] || ", "hits": 158 }, { "id": 40348, "url": "https://svs.gsfc.nasa.gov/gallery/esddatafor-societal-benefits/", "result_type": "Gallery", "release_date": "2018-04-24T00:00:00-04:00", "title": "ESD data for Societal Benefit", "description": "No description available.", "hits": 228 }, { "id": 4582, "url": "https://svs.gsfc.nasa.gov/4582/", "result_type": "Visualization", "release_date": "2017-07-27T18:00:00-04:00", "title": "Aerosol Optical Thickness Updating Forecast", "description": "The atmosphere is made up of gases like oxygen, nitrogen, and water vapor, but it also contains tiny particles called aerosols. Aerosols come from both natural and human sources and include things like sea salt, dust, soot, and sulfates. Aerosols often contribute to air pollution and poor visibility. Once they are in the atmosphere, they can travel long distances, affecting air quality far from their source. Aerosols also absorb or reflect energy (light), influencing temperatures in the atmosphere and on the ground. Satellites measure aerosols by how much light can pass through them. A thick layer of aerosols will block the ground from view, while a thin layer allows enough light through to see the ground. The measurement is called aerosol optical thickness.The GEOS model is built on satellite data and provides a forecast of aerosol optical thickness (among other things). This animation shows a daily updated 10-day forecast of aerosol optical thickness from GEOS. The date and timestamp are in the lower left corner. In general, brighter colors are thick aerosols, while dull darker colors are thin aerosols. Blue represents sea salt (sea salt extinction aerosol optical thickness, 550 nm). Winds blowing across the ocean kicks up ocean spray, which includes sea salt. In the animation, pale blue to white colors reflect stormy conditions. Individual large storms like tropical cyclones (hurricanes, typhoons) are visible as swirling circles of thick sea salt. Red represents dust (dust extinction aerosol optical thickness, 550 nm). The Saharan Desert of northern Africa is the largest source of dust, but dust can be seen across the globe. Saharan dust often interacts with tropical cyclones.Green represents the sum of aerosol optical thickness for organic carbon, black carbon, and sulfate. Organic and black carbon come from burning biomass or fossil fuels. Sources include fires, power plants, vehicles, and other combustion engines that run on fossil fuel. Sulfate particles come mostly from burning fossil fuels, but also from volcanoes. || gmao_aerosols_print.jpg (1024x576) [201.6 KB] || gmao_aerosols_searchweb.png (320x180) [108.3 KB] || gmao_aerosols.00001_thm.png (80x40) [7.0 KB] || gmao_aerosols.mp4 (1920x962) [16.2 MB] || gmao_aerosols.webm (1920x962) [1.5 MB] || latest-wdates (2239x1123) [0 Item(s)] || latest-nodates (2239x1123) [0 Item(s)] || gmao_aerosols.mp4.hwshow [191 bytes] || ", "hits": 56 }, { "id": 40323, "url": "https://svs.gsfc.nasa.gov/gallery/applied-science/", "result_type": "Gallery", "release_date": "2017-03-30T00:00:00-04:00", "title": "Applied Science", "description": "Discovering innovative and practical uses of Earth observations\n\nappliedsciences.nasa.gov", "hits": 73 }, { "id": 12508, "url": "https://svs.gsfc.nasa.gov/12508/", "result_type": "Produced Video", "release_date": "2017-02-09T14:00:00-05:00", "title": "ATom Postcard - Alaska and the Arctic", "description": "On its second worldwide tour, the Atmospheric Tomography (ATom) team starts by surveying the north’s polar regions during winter, which is marked by a build-up of pollution from the United States, Canada, northern China, and Russia.

While ozone gas located high in the stratosphere protects us from the sun’s harmful UV rays, pollution from cars and other human emissions near ground level can cause chemical reactions that lead to ozone formation near the surface. Breathing in high levels of ozone is also bad for human health, causing lung diseases and health impacts on sensitive populations such as children, the elderly and people with asthma. These visuals are showing the ozone that formed near the surface, or 'surface ozone', over the Korean peninsula in June 2013 according to the GEOS-5 Nature Run chemistry model data. Peak ozone in Korea occurs between April and June.Since Seoul is located on a peninsula, the metropolitan area and the pollution produced here are separated from other sources of emissions. In addition, Seoul’s human-produced emissions are concentrated in its urban areas but are surrounded by more rural agricultural areas. The contrast between urban and rural zones on the peninsula allow scientists to study and differentiate human and naturally-produced emissions and better understand how they interact chemically. Understanding the chemical reactions between urban and agricultural emissions is extremely important for improving models that forecast air quality. || ", "hits": 24 }, { "id": 4412, "url": "https://svs.gsfc.nasa.gov/4412/", "result_type": "Visualization", "release_date": "2015-12-17T00:00:00-05:00", "title": "NASA Images Show Human Fingerprint on Global Air Quality – Release Materials", "description": "This video provides an overview of the study findings.

Scientists examined observations made from 2005 to 2014 by the Ozone Monitoring Instrument aboard NASA's Aura satellite. One of the atmospheric gases the instrument detects is nitrogen dioxide, a yellow-brown gas that is a common emission from cars, power plants and industrial activity. Nitrogen dioxide can quickly transform into ground-level ozone, a major respiratory pollutant in urban smog. Nitrogen dioxide hotspots, used as an indicator of general air quality, occur over most major cities in developed and developing nations.The following visualizations include two types of data. The absolute concentrations show the concentration of tropospheric nitrogen dioxide, with blue and green colors denoting lower concentrations and orange and red areas indicating higher concentrations. The second type of data is the trend data from 2005 to 2014, which shows the observed change in concentration over the ten-year period.

A continuous belt of higher carbon dioxide concentrations circled an area in the Southern Hemisphere that covered the tip of South America, Africa and southern Australia. Computer models that predict how chemicals move throughout the atmosphere did not predict this band. Scientists now think that strong thunderstorms and winds that flow around South America's high Andes Mountains lift carbon dioxide into what's called the \"free troposphere.\" There it becomes trapped in the jet stream of the mid-latitudes, which propel it around the world. The sources of this belt are many: industry and power plants in coal-rich South Africa, electricity generation in eastern Australia and in Buenos Aires, Argentina, as well as plant respiration and fires.

Nearly a billion people crowd that plain, an area about the size of Texas. The region's explosive population growth and strong economy in recent decades have produced an unwelcome byproduct—air pollution. Burning fossil fuels, wood, vegetation and dung sends a steady stream of soot (or, black carbon, as scientists call the light-absorbing particles) aloft. Studies show India's black carbon emissions have jumped about 60 percent per decade in the last two decades. The short-lived particles typically remain in the atmosphere for less than a week, but they pool over the Indo-Gangetic plain as monsoon-fueled winds trap them along the Himalayas. The particles, the most health-sapping part of air pollution, also have a potent climate impact. Unlike most other types of particulate, black carbon absorbs radiation, warming the atmosphere and contributing to the retreat of glaciers in the area.

Discover - AQ is a four-year campaign to improve the use of satellites to monitor air quality for public health and environmental benefit. The fundamental challenge for satellites measuring air quality is to distinguish between pollution near the surface and pollution higher in the atmosphere. Scientific questions remain about the vertical distribution of pollutants. How far up in the atmosphere are morning and evening spikes in pollution associated with rush hour noticeable? How does ozone, which peaks near the surface in afternoon, behave at other altitudes throughout the day? When is the best time of the day for satellites to measure various pollutants?Measurements from aircraft, in combination with ground-based measurements, offer a key perspective that makes such distinctions easier to make. The problem is particularly pronounced for pollutants that are abundant at the surface and higher in the atmosphere. For example, a \"Code Red\" air-quality day during the summer might produce very high concentrations of ozone in the bottom few kilometers of the atmosphere, yet generate a change of a mere 1 or 2 percent to a total column of ozone. Studies suggest that discrepancies of as much as 30 to 50 percent exist between estimates of ground nitrogen dioxide inferred from the Ozone Monitoring Instrument(OMI), an instrument on NASA's Aura satellite launched in 2004, and measurements from ground-based instruments. DISCOVER-AQ will address such problems by helping researchers develop a three-dimensional view of how air pollutants are distributed and move between different levels of the atmosphere throughout the day.A phalanx of ground-based instruments will offer a critical view of the same patches of air the aircraft are monitoring from above. While NASA sponsors certain ground instruments, other institutions including the Environmental Protection Agency, the Maryland Department of the Environment, Howard University, and Pennsylvania State University manage the instruments at the ground stations.Scientists will use information collected during the DISCOVER-AQ campaign to improve measurements from existing satellites and to help establish parameters for future NASA satellite missions that will monitor air quality.

Four satellites currently fly in the A-Train - Aqua, CloudSat, CALIPSO, and Aura. Three more satellites -- Glory, GCOM-W1, and OCO-2 -- are scheduled to join the configuration in 2011, 2012, and 2013, respectively. This page features a selection of some of the A-Train's \"greatest hits\" gathered into two sections. The first contains overview materials giving a big-picture look of the A-Train and NASA satellites. The second section contains mostly visualizations featuring a single instrument or instruments on A-Train satellites. (For the purposes of this page, each visual has been labeled with the A-Train data set it was produced from, but keep in mind, visuals are often the product of many data sets from many different satellites.)

This process, called fixing, is one of the main ways in which carbon dioxide is removed from the atmosphere and is a major part of the carbon cycle. Plants release a fraction of this fixed carbon by respiration in order to get energy to live and to move carbon to other organs. The amount of carbon removed minus the amount of carbon respired is called the net primary productivity (NPP) and is the amount of carbon turned into biomass.The change in NPP due to rising global temperatures is a very important factor in the response of the Earth to climate change. Measurements of radiation and leaf area from the MODIS instrument on NASA's Terra satellite have recently been used to calculate the change in NPP for the whole world for the last 10 years. This animation shows a time sequence of annual NPP deviation from normal (or 'anomaly') on land as measured by MODIS during the years 2000 through 2009. Annual NPP, especially its departures from a long-term mean condition, will demonstrate the effects of environmental drivers such as ENSO (El Niño) events, climate change, droughts, pollution episodes, land degradation, and agricultural expansion.Earlier studies of productivity between 1982 and 1999 showed that prouctivity went up as global temperatures rose, because longer, warmer growing seasons were better for plant growth. This new study indicates that this is still true in the northern hemisphere, but that increased temperatures have meant increased drought and dryness in the tropics and the southern hemisphere. As a result, the global net productivity has actually decreased in the period from 2000 through 2009.Regionally, negative annual NPP anomalies were mainly caused by large-scale droughts. In 2000, droughts reduced NPP in North America and China; in 2002, droughts reduced NPP in North America and Australia; in 2003, drought caused by a major heat wave reduced NPP in Europe; in 2005, severe droughts in the Amazon, Africa, and Australia greatly reduced both regional and global NPP; from 2007 through 2009 over large parts of Australia, continuous droughts reduced continental NPP.For an animation of daily productivity, see the page How Much Carbon do Plants Take from the Atmosphere?. || ", "hits": 112 }, { "id": 40075, "url": "https://svs.gsfc.nasa.gov/gallery/energy-essentials/", "result_type": "Gallery", "release_date": "2010-08-17T00:00:00-04:00", "title": "Energy Essentials", "description": "Energy.

Tropospheric ozone is close the ground and a component of pollution. This should be distinguished from high-altitude (stratospheric) ozone which shields the Earth's surface from ultraviolet radiation. Ozone measurements from the OMI and MLS instruments on board the Aura satellite are used for deriving global distributions of tropospheric column ozone (TCO). TCO is determined using the tropospheric ozone residual method which involves subtracting measurements of MLS stratospheric column ozone (SCO) from OMI total column ozone after adjusting for intercalibration differences of the two instruments using the convective-cloud differential method. The derived TCO field, which covers one complete year of mostly continuous daily measurements from January 2005 through December 2006, is used for studying the regional and global pollution on a timescale of a few days to months. MLS and OMI are two out of a total of four instruments on board the Aura spacecraft which is flown in a sunsynchronous polar orbit at 705 km altitude with a 98.2 degree inclination. The spacecraft has an equatorial crossing time of 1:45 pm (ascending node) with around 98.8 min per orbit (14.6 orbits per day on average). OMI is a nadir-scanning instrument that at visible (350-500 nm) and UV wavelength channels (UV-1: 270-314 nm; UV-2: 306-380 nm) detects backscattered solar radiance to measure column ozone. The MLS instrument is a thermal-emission microwave limb sounder that measures vertical profiles of mesospheric, stratospheric, and upper tropospheric temperature, ozone and other constituents from limb scans ahead of the Aura satellite. The MLS profile measurements are taken about 7 min before OMI views the same location during ascending (daytime) orbital tracks. These are referred as \"collocated\" measurements between OMI and MLS. The data shows signals due to convection, biomass burning, stratospheric influence, pollution, and transport. They are capable of capturing the spatiotemporal evolution of tropospheric column ozone.

Pollution in the atmosphere creates smaller, brighter cloud droplets that reflect more sunlight back to space and may have a slight impact on global warming.This narrated visualization illustrates how we can study the effect against a clean backdrop by looking for zones of pollution in otherwise pristine air - in this case the North Pacific Ocean near the Aleutian islands. On an overcast day, the clouds look uniform. However, MODIS' sesor reveals a different picture - long skinny trails of brighter clouds hidden within. As ships travel across the ocean, pollution in the ships' exhaust create more cloud drops that are smaller in size, resulting in even brighter clouds. On clear days, ships can actually create new clouds. Water vapor condenses around the particles of pollution, forming streamers of clouds as the ships travel on. The ship tracks themselves are too small to impact global temperatures, but they help us understand how larger pollution sources such as industrial sites or agricultural burning might be changing clouds on a larger scale. || ", "hits": 66 }, { "id": 10562, "url": "https://svs.gsfc.nasa.gov/10562/", "result_type": "Produced Video", "release_date": "2010-05-27T00:00:00-04:00", "title": "Gulf of Mexico Oil Spill", "description": "You can learn more about NASA's satellite observations of the oil spill by visiting https://www.nasa.gov/topics/earth/features/oilspill/. || ", "hits": 56 }, { "id": 10612, "url": "https://svs.gsfc.nasa.gov/10612/", "result_type": "Produced Video", "release_date": "2010-05-12T00:00:00-04:00", "title": "The Smog Bloggers", "description": "Has pollen got you sneezing?
