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": 38 }, { "id": 4916, "url": "https://svs.gsfc.nasa.gov/4916/", "result_type": "Visualization", "release_date": "2021-08-09T00:00:00-04:00", "title": "Normalized Difference Vegetation Index (NDVI) Anomaly in crop-growing regions for selected years", "description": "This visualization shows the NDVI anomaly in areas where maize, rice, soybeans, spring wheat or winter wheat are grown over the United States, Australia, Russia, Europe and southern Africa during certain years.

EPIC provides high quality, color images of Earth, which are useful for monitoring factors like the planet’s vegetation, cloud height, and ozone. And every once in a while –– most recently, June 10, 2021 –– it has the opportunity to capture a solar eclipse.A solar eclipse occurs when the Moon is positioned between the Sun and Earth, leading the Moon’s shadow to be projected onto Earth. During a total solar eclipse, the Moon completely blocks the Sun. During an annular solar eclipse, like the one on June 10, the Moon is near its farthest point from Earth and appears smaller than the Sun in the sky. As the two align, the Sun appears as a ring of fire surrounding the dark disk of the Moon. On June 10, viewers in parts of Canada, Greenland, and Russia were treated to a full annular eclipse. People in a handful of other locations, including parts of the Caribbean, Asia, Europe, eastern United States, Alaska, and northern Africa, were able to catch a partial solar eclipse, where only part of the Sun is blocked by the Moon, leaving behind a crescent-shaped piece of Sun.

Probably the most famous of those eruptions occurred in 79 A.D., when pyroclastic flows destroyed the cities of Pompeii and Herculaneum, trapping more than 16,000 people. Such historic catastrophes—and the fact that 600,000 people currently live in the immediate vicinity—are why the volcano is one of the most heavily monitored in the world, with several dozen sensors located at many points on and around the cone.The different colors of lights in the scene reflect some of the history of development in the area. The green lights are mercury vapor bulbs, an older variety that has been replaced in newer developments by yellow-orange sodium bulbs. To the northeast, the lightless gaps between the homes and businesses are agricultural fields. The bright yellow-orange complex amidst the fields is the Consorzio Intercomunale dei Servizi, the largest commercial facility in Europe. || Unpop_Slopes_Active_Volcan_Naples_It_print.jpg (1024x540) [202.8 KB] || Unpop_Slopes_Active_Volcan_Naples_It.png (4096x2160) [15.3 MB] || Unpop_Slopes_Active_Volcan_Naples_It_searchweb.png (320x180) [109.9 KB] || Unpop_Slopes_Active_Volcan_Naples_It_thm.png (80x40) [6.6 KB] || unpopulated-slopes-of-an-active-volcanonaples-italy.hwshow [347 bytes] || ", "hits": 50 }, { "id": 14190, "url": "https://svs.gsfc.nasa.gov/14190/", "result_type": "Produced Video", "release_date": "2019-11-07T00:00:00-05:00", "title": "NASA Explorers | Season Three: Fires", "description": "Complete transcript available. || S3_Trailer_Thumbnail.png (2136x1102) [999.3 KB] || S3_Trailer_V2.mov (3840x2160) [2.8 GB] || S3_Trailer_V2.mp4 (3840x2160) [44.3 MB] || S3_Trailer_V2.webm (3840x2160) [9.7 MB] || S3_Trailer_Captions.en_US.srt [846 bytes] || S3_Trailer_Captions.en_US.vtt [858 bytes] || ", "hits": 27 }, { "id": 13300, "url": "https://svs.gsfc.nasa.gov/13300/", "result_type": "Produced Video", "release_date": "2019-08-29T06:10:00-04:00", "title": "New NASA Images Show Summer Melting In The Arctic Live Shots", "description": "Click HERE for quick link to audio soundbites.Click for quick link to B-ROLL for these live shotsClick for quick link to canned interview with NASA Scientist Tom NeumannClick for quick link to canned interview with NASA scientist Nathan KurtzClick for quick lin to canned interview in Spanish with NASA Scientist Edil Sepulveda || Screen_Shot_2019-08-28_at_3.03.24_PM.png (2956x450) [1.9 MB] || Screen_Shot_2019-08-28_at_3.03.24_PM_print.jpg (1024x155) [36.0 KB] || Screen_Shot_2019-08-28_at_3.03.24_PM_searchweb.png (320x180) [75.9 KB] || Screen_Shot_2019-08-28_at_3.03.24_PM_thm.png (80x40) [4.9 KB] || ", "hits": 179 }, { "id": 4746, "url": "https://svs.gsfc.nasa.gov/4746/", "result_type": "Visualization", "release_date": "2019-08-08T08:00:00-04:00", "title": "June 2019 Monthly Global Temperature Anomalies", "description": "While many people in the continuous United States saw average temperatures in the month of June 2019, the average global temperature in June was 1.71 degrees F above the 20th-century average of 59.9 degrees.

They also portray the structure of the glacier ice that flows into and fills the crater.The Hiawatha impact crater was first suspected to exist in the summer of 2015, from examination of a compilation of Greenland's sub-ice topography radar measurements made by NASA over two decades. The visualizations of the subsurface shown below are derived from a spring 2016 airborne survey by Germany's Alfred Wegener Institute, using a new ultrawideband radar sounder developed by the Center for Remote Sensing of Ice Sheets at The University of Kansas. Subsequent helicopter visits to the deglaciated terrain in front of Hiawatha Glacier by scientists from the Natural History Museum in Denmark recovered sediment samples from the main river that discharges water from beneath Hiawatha Glacier, through the northwestern rim breach. Laboratory examination revealed that these sediment samples contained shocked quartz and elevated platinum-group-element concentrations, both signs that the sediment records evidence of the impact of an iron asteroid more than one kilometer wide. The Hiawatha impact crater is potentially one of the youngest large impact craters on Earth.In the visualizations below, the elevation of the topography of the bed, the ice surface and the radar curtains have been exaggerated ten times in order to better illustrate their structure. || ", "hits": 189 }, { "id": 40365, "url": "https://svs.gsfc.nasa.gov/gallery/earth-science-oct2018-briefing/", "result_type": "Gallery", "release_date": "2018-10-18T00:00:00-04:00", "title": "Earth Science Overview Oct 2018 Briefing", "description": "No description available.", "hits": 89 }, { "id": 12983, "url": "https://svs.gsfc.nasa.gov/12983/", "result_type": "Produced Video", "release_date": "2018-08-27T12:00:00-04:00", "title": "Dust in the Wind", "description": "Dust, salt and smoke swirling in the air tell a story of summer 2017. || CoverStill.png (1920x1080) [2.3 MB] || CoverStill_1024x576.jpg (1024x576) [130.9 KB] || CoverStill_print.jpg (1024x576) [140.9 KB] || CoverStill_searchweb.png (320x180) [110.4 KB] || CoverStill_thm.png (80x40) [7.7 KB] || ", "hits": 46 }, { "id": 12963, "url": "https://svs.gsfc.nasa.gov/12963/", "result_type": "Produced Video", "release_date": "2018-06-02T15:00:00-04:00", "title": "Airglow Imagery", "description": "Airglow occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light in order to shed their excess energy.

Airglow carries information on the upper atmosphere’s temperature, density, and composition, but it also helps us trace how particles move through the region itself.

The heat, accompanied by moist air, is entering the Arctic not only through the sector of the North Atlantic Ocean that lies between Greenland and Europe, as it has done in previous years, but is also coming from the North Pacific through the Bering Strait. “We have seen winter warming events before, but they’re becoming more frequent and more intense,” said Alek Petty, a sea ice researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Scientists are waiting to see how much this heat wave will impact the wintertime sea ice maximum extent, which has been shrinking in the past decades and has hit record lows each of the past three years. The sea ice levels are already at record lows or near-record lows in several areas of the Arctic. Another exceptional event this winter is the opening up of the sea ice cover north of Greenland, releasing heat from the ocean to the atmosphere and making the sea ice more vulnerable to further melting. “This is a region where we have the thickest multi-year sea ice and expect it to not be mobile, to be resilient,” Petty said. “But now this ice is moving pretty quickly, pushed by strong southerly winds and probably affected by the warm temperatures, too.” || ", "hits": 28 }, { "id": 12774, "url": "https://svs.gsfc.nasa.gov/12774/", "result_type": "Produced Video", "release_date": "2017-11-13T16:00:00-05:00", "title": "Stunning New Global Portrait Celebrates 20 Years of Studying Life on Earth from Space Live Shots", "description": "B-roll package for November 17 liveshots.

According to recent NASA research findings, the United States, Europe and Japan have improved air quality thanks to emission control regulations, while China, India and the Middle East, with their fast-growing economies and expanding industry, have seen more air pollution. 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. Blue indicated an observed decrease in nitrogen dioxide, and orange indicates an observed increase. Please note that the range on the color bars (text is in white) changes from location to location in order to highlight features seen in the different geographic regions. || ", "hits": 140 }, { "id": 12096, "url": "https://svs.gsfc.nasa.gov/12096/", "result_type": "Produced Video", "release_date": "2015-12-14T13:00:00-05:00", "title": "Human Fingerprint on Global Air Quality", "description": "For complete transcript, click here. || NO2_poster_frame_print.jpg (1024x576) [145.6 KB] || NO2_poster_frame_searchweb.png (320x180) [83.9 KB] || NO2_poster_frame_web.png (320x180) [83.9 KB] || NO2_poster_frame_thm.png (80x40) [14.0 KB] || 12096-MASTER_appletv.m4v (1280x720) [60.8 MB] || 12096-MASTER_prores.webm (1280x720) [12.6 MB] || NO2_poster_frame.tif (1920x1080) [6.0 MB] || 12096-MASTER_appletv_subtitles.m4v (1280x720) [60.8 MB] || 12096-MASTER_ipod_sm.mp4 (320x240) [22.1 MB] || NO2_12.en_US.srt [2.4 KB] || NO2_12.en_US.vtt [2.4 KB] || 12096-MASTER.mov (1920x1080) [3.4 GB] || 12096-MASTER_prores.mov (1280x720) [1.7 GB] || 12096-MASTER.mpeg (1280x720) [421.6 MB] || ", "hits": 89 }, { "id": 30693, "url": "https://svs.gsfc.nasa.gov/30693/", "result_type": "Hyperwall Visual", "release_date": "2015-10-20T00:00:00-04:00", "title": "Southwestern Europe and Australia at Night 2014-2015", "description": "One way to study the spatial distribution, or arrangement, of human settlements is to view the planet from space during nighttime hours. Scientists have observed the Earth’s lights at night for more than four decades using military satellites and astronaut photography; however, the view became significantly clearer after using satellite data from a low-light sensor onboard the Suomi National Polar-orbiting Partnership (NPP) satellite, launched in October 2011. The satellite’s Visible Infrared Imaging Radiometer Suite (VIIRS) “day-night band” can observe dim signals such as city lights (down to the scale of an isolated highway lamp), wildfires, gas flares, auroras, and reflected moonlight during nighttime hours. Swaths of VIIRS data are processed to find moonless, non-cloudy pixels. These “good” pixels are averaged at each location to produce a global image that depicts the Earth’s lights at night. Each pixel shows roughly 0.46 miles (742 meters) across.The top image, centered on France, is a composite of VIIRS data acquired between October 1, 2014 and April 30, 2015. Paris is visible just above the center of the image. North of Paris and across the English Channel (black), London is visible. The relatively dim Alps, characterized by their crescent-shaped geography, are speckled with lights from car headlights and lit roadways. South of the Alps several major cities in Italy are visible with the brightest spot being Milan. Rome is visible in the bottom right of the image. Strings and clusters of light out at sea are produced by ship lights. The second image, centered on France, is a composite of data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) acquired during 2013. Each pixel shows roughly 1.86 miles (3 kilometers) across. The DMSP OLS night-lights data are available starting in 1992, and provide the ability to measure changes in light extent and locations over the past two decades.The image of Australia at night is a composite of VIIRS data acquired between January 1, 2015 and July 31, 2015. Major cities such as Brisbane, Sydney, Melbourne, and Perth are well lit along the coast. Alice Springs—situated in the geographic center of Australia—is some 1,500 kilometers from the nearest major city. Transient lights—those visible in only one monthly image—are colored red. These lights are mainly from brushfires burning during the dry season (May-July) in Australia’s Northern Territory and northern parts of Western Australia. Aside from fires, some of the transient lights could be attributed to natural gas flares, lightning, oil drilling, or mining operations. || ", "hits": 112 }, { "id": 4341, "url": "https://svs.gsfc.nasa.gov/4341/", "result_type": "Visualization", "release_date": "2015-09-01T00:00:00-04:00", "title": "September 27, 2015 Total Lunar Eclipse: View from the Moon", "description": "With the lunar horizon in the foreground, the Earth passes in front of the Sun, revealing the red ring of sunrises and sunsets along the limb of the Earth.

Black carbon and organic carbon are produced from the burning of fossil fuels, like coal and oil, as well as biofuels and biomass, such as forests.With their snow darkening effect added to NASA’s GEOS-5 climate model, scientists analyzed results from 2002 to 2011, and compared them to model runs done without the aerosols on snow.

Over broad places in the Northern Hemisphere, the darkened snow caused some surface temperatures to be up to 10 degrees Fahrenheit warmer than it would be if the snow were pristine. As a result, warmer, snow-darkened areas had less snow in spring than they would have had under pristine snow conditions.According to the study, dust’s snow darkening effect significantly contributed to surface warming in Central Asia and the western Himalayas.

On July 6, 2015, a NASA camera onboard the Deep Space Climate Observatory (DSCOVR) satellite returned its first view of the entire sunlit side of Earth from its orbit at the first Lagrange point (L1), about one million miles from Earth. This initial image, taken by DSCOVR’s Earth Polychromatic Imaging Camera (EPIC), shows the effects of sunlight scattered by air molecules, giving the image a characteristic bluish tint. Once the instrument begins regular data acquisition, images will be available every day, 12 to 36 hours after they are acquired by EPIC.

Snow also absorbs energy from the atmosphere during spring melt, keeping temperatures moderate. Satellite measurements of snow extent began in the 1960s, and this lengthy record shows a 10 percent decline in annual snow cover since 1966, mainly due to earlier spring melting. Darker, snow-free ground absorbs more solar radiation and emits more warmth to the atmosphere. The snow cover loss is also a concern for those who depend on snowmelt for drinking water.
