Increases in greenhouse gases, like carbon dioxide and methane, trap emitted thermal radiation from the surface and reduce how much is lost to space, resulting in a net surplus of energy into the Earth system. Most of the extra energy ends up being stored as heat in the ocean and the remainder warms the atmosphere and land, and melts snow and ice. As a consequence, global mean surface temperature increases and sea levels rise. Much like a pulse or heartbeat, CERES monitors reflected solar and emitted thermal infrared radiation, which together with solar irradiance measurements is one of Earth’s ‘vital signs.’ Better understanding Earth’s energy balance enables us to be informed and adapt to a changing world. || ", "hits": 220 }, { "id": 31112, "url": "https://svs.gsfc.nasa.gov/31112/", "result_type": "Hyperwall Visual", "release_date": "2020-02-12T00:00:00-05:00", "title": "Electric Eye of Cyclone Bansi in the Indian Ocean", "description": "2 ISS views of Cyclone Bansi || electric-eye-cyclone_print.jpg (1024x576) [80.7 KB] || electric-eye-cyclone.png (3840x2160) [11.8 MB] || electric-eye-cyclone_searchweb.png (320x180) [61.7 KB] || electric-eye-cyclone_thm.png (80x40) [4.6 KB] || electric-eye-of-cyclone-bansi-in-the-indian-ocean.hwshow [313 bytes] || ", "hits": 34 }, { "id": 31115, "url": "https://svs.gsfc.nasa.gov/31115/", "result_type": "Hyperwall Visual", "release_date": "2020-02-12T00:00:00-05:00", "title": "Airglow over Australia", "description": "airglow over australia seen from the ISS || airglow-australia_print.jpg (1024x576) [150.3 KB] || airglow-australia.png (3840x2160) [15.1 MB] || airglow-australia_searchweb.png (320x180) [80.8 KB] || airglow-australia_thm.png (80x40) [4.7 KB] || airglow-over-australia.hwshow [280 bytes] || ", "hits": 66 }, { "id": 31097, "url": "https://svs.gsfc.nasa.gov/31097/", "result_type": "Hyperwall Visual", "release_date": "2020-01-31T00:00:00-05:00", "title": "Nighttime Panorama—Pakistan’s Indus River Valley", "description": "Nighttime Panorama—Pakistan’s Indus River Valley || Page21_IndiaPakistan_Hyperwall_5760x3240_19.2x10.8_print.jpg (1024x576) [91.3 KB] || Page21_IndiaPakistan_Hyperwall_5760x3240_19.2x10.8.png (5760x3240) [11.4 MB] || Page21_IndiaPakistan_Hyperwall_5760x3240_19.2x10.8_searchweb.png (320x180) [76.4 KB] || Page21_IndiaPakistan_Hyperwall_5760x3240_19.2x10.8_thm.png (80x40) [5.4 KB] || nighttime-panoramapakistans-indus-river-valley.hwshow [370 bytes] || ", "hits": 93 }, { "id": 31098, "url": "https://svs.gsfc.nasa.gov/31098/", "result_type": "Hyperwall Visual", "release_date": "2020-01-31T00:00:00-05:00", "title": "Beyond City Lights—Java Sea", "description": "Beyond City Lights—Java Sea || Page23JAVASEA_Hyperwall_5760x3240_19.2x10.8_print.jpg (1024x576) [114.4 KB] || Page23JAVASEA_Hyperwall_5760x3240_19.2x10.8.png (5760x3240) [13.6 MB] || Page23JAVASEA_Hyperwall_5760x3240_19.2x10.8_searchweb.png (320x180) [78.2 KB] || Page23JAVASEA_Hyperwall_5760x3240_19.2x10.8_thm.png (80x40) [4.7 KB] || beyond-city-lightsjava-sea.hwshow [336 bytes] || ", "hits": 91 }, { "id": 31059, "url": "https://svs.gsfc.nasa.gov/31059/", "result_type": "Hyperwall Visual", "release_date": "2019-11-13T00:00:00-05:00", "title": "CERES top of Atmosphere Fluxes", "description": "These maps show monthly top of atmosphere radiative fluxes from March 2000 to the present from the Energy Balanced and Filled (EBAF) data product.

If you peer down on Earth from just 300 miles above the surface, near the orbit of the International Space Station, you can see vibrant swaths of red and green or purple and yellow light emanating from the upper atmosphere. This is airglow. Airglow occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light in order to shed their excess energy. Or, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron. In both cases, they eject a particle of light — called a photon — in order to relax again.

Together, GOLD and another NASA mission, Ionospheric Connection Explorer spacecraft, or ICON, will provide the most comprehensive of Earth’s upper atmosphere we’ve ever had.Above the ozone layer, the ionosphere is a part of Earth’s atmosphere where particles have been cooked into a sea of electrically-charged electrons and ions by the Sun’s radiation. The ionosphere is co-mingled with the very highest — and quite thin — layers of Earth’s neutral upper atmosphere, making this region an area that is constantly in flux undergoing the push-and-pull between Earth’s conditions and those in space. Increasingly, these layers of near-Earth space are part of the human domain, as it’s home not only to astronauts, but to radio signals used to guide airplanes and ships, and satellites that provide our communications and GPS systems. Understanding the fundamental processes that govern our upper atmosphere and ionosphere is crucial to improve situational awareness that helps protect astronauts, spacecraft and humans on the ground.GOLD, in geostationary orbit over the Western Hemisphere, will build up a full-disk view of the ionosphere and upper atmosphere every half hour, providing detailed large-scale measurements of related processes — a cadence which makes it the first mission to be able to monitor the true weather of the upper atmosphere. GOLD is also able to focus in on a tighter region and scan more quickly, to complement additional research plans as needed. || ", "hits": 63 }, { "id": 30920, "url": "https://svs.gsfc.nasa.gov/30920/", "result_type": "Hyperwall Visual", "release_date": "2017-12-11T00:00:00-05:00", "title": "Total Ozone and UV, 2017", "description": "Southern hemisphere ozone 2017 || ozone_sh_20171130_print.jpg (1024x574) [48.8 KB] || ozone_sh_20171130.png (4104x2304) [1.3 MB] || ozone_sh_20171130_searchweb.png (320x180) [32.4 KB] || ozone_sh_20171130_thm.png (80x40) [3.5 KB] || test.hwshow [319 bytes] || ", "hits": 54 }, { "id": 12532, "url": "https://svs.gsfc.nasa.gov/12532/", "result_type": "Produced Video", "release_date": "2017-11-07T14:00:00-05:00", "title": "Welcome to the Ionosphere", "description": "Music credit: Foxy Trot by Luis Enriquez Bacalov Complete transcript available.Watch this video on the NASA Goddard YouTube channel. || ionosphere_thumb.jpg (1920x1080) [69.9 KB] || ionosphere_thumb_searchweb.png (320x180) [57.3 KB] || ionosphere_thumb_thm.png (80x40) [6.3 KB] || APPLE_TV-12532_Welcome_to_the_ionosphere_bsideV4_appletv.webm (1280x720) [24.0 MB] || APPLE_TV-12532_Welcome_to_the_ionosphere_bsideV4_appletv.m4v (1280x720) [116.4 MB] || APPLE_TV-12532_Welcome_to_the_ionosphere_bsideV4_appletv_subtitles.m4v (1280x720) [116.5 MB] || YOUTUBE_1080-12532_Welcome_to_the_ionosphere_bsideV4_youtube_1080.mp4 (1920x1080) [346.2 MB] || NASA_TV-12532_Welcome_to_the_ionosphere_bsideV4.mpeg (1280x720) [691.7 MB] || 12532_Welcome_to_the_ionosphere_bsideV2_lowres.en_US.srt [3.8 KB] || 12532_Welcome_to_the_ionosphere_bsideV2_lowres.en_US.vtt [3.8 KB] || 12532_Welcome_to_the_ionosphere_bsideV4_lowres.mp4 (480x272) [29.2 MB] || LARGE_MP4-12532_Welcome_to_the_ionosphere_bsideV4_large.mp4 (3840x2160) [220.8 MB] || NASA_PODCAST-12532_Welcome_to_the_ionosphere_bsideV4_ipod_sm.mp4 (320x240) [37.3 MB] || 12532_Welcome_to_the_ionosphere_bsideV4.mov (3840x2160) [10.1 GB] || ", "hits": 110 }, { "id": 12699, "url": "https://svs.gsfc.nasa.gov/12699/", "result_type": "Produced Video", "release_date": "2017-10-18T14:00:00-04:00", "title": "Meet ICON: NASA’s Airglow Explorer", "description": "Music credit: Design Principle by Wayne RobertsComplete transcript available. || iss_composite_test_182.jpg (4256x2832) [12.8 MB] || iss_composite_test_182_searchweb.png (320x180) [99.0 KB] || iss_composite_test_182_thm.png (80x40) [6.2 KB] || LARGE_MP4-12699_ICON_Overview_V2__large.mp4 (1920x1080) [148.3 MB] || NASA_TV-12699_ICON_Overview_V2_.mpeg (1280x720) [494.2 MB] || APPLE_TV-12699_ICON_Overview_V2__appletv.m4v (1280x720) [75.3 MB] || YOUTUBE_1080-12699_ICON_Overview_V2__youtube_1080.mp4 (1920x1080) [234.8 MB] || PRORES_B-ROLL-12699_ICON_Overview_V2__prores.mov (1280x720) [1.9 GB] || YOUTUBE_HQ-12699_ICON_Overview_V2__youtube_hq.mov (1920x1080) [539.3 MB] || 12699_ICON_Overview_V2_.mov (1920x1080) [3.7 GB] || LARGE_MP4-12699_ICON_Overview_V2__large.webm (1920x1080) [16.3 MB] || APPLE_TV-12699_ICON_Overview_V2__appletv_subtitles.m4v (1280x720) [75.3 MB] || 12699_ICON_Overview_V2.en_US.srt [2.4 KB] || 12699_ICON_Overview_V2.en_US.vtt [2.5 KB] || NASA_PODCAST-12699_ICON_Overview_V2__ipod_sm.mp4 (320x240) [25.4 MB] || 12699_ICON_Overview_V2__lowres.mp4 (480x272) [20.3 MB] || ", "hits": 54 }, { "id": 20265, "url": "https://svs.gsfc.nasa.gov/20265/", "result_type": "Animation", "release_date": "2017-04-03T13:00:00-04:00", "title": "ICON Beauty Pass", "description": "Beauty pass showing ICON observing the ionosphere.

The doors are open on NASA's Suomi NPP satellite and the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system.CERES products include both solar-reflected and Earth-emitted radiation from the top of the atmosphere to the Earth's surface. Cloud properties are determined using simultaneous measurements by other EOS and NPP instruments such as the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible and Infrared Sounder (VIRS). Analyses using CERES data, build upon the foundation laid by previous missions such as NASA Earth Radiation Budget Experiment (ERBE), leading to a better understanding of the role of clouds and the energy cycle in global climate change. The sun's radiant energy is the fuel that drives Earth's climate engine. The Earth-atmosphere system constantly tries to maintain a balance between the energy that reaches the Earth from the sun and the energy that flows from Earth back out to space. Energy received from the sun is mostly in the visible (or shortwave) part of the electromagnetic spectrum. About 30% of the solar energy that comes to Earth is reflected back to space. The ratio of reflected-to-incoming energy is called \"albedo\" from the Latin word meaning whiteness. The solar radiation absorbed by the Earth causes the planet to heat up until it is radiating (or emitting) as much energy back into space as it absorbs from the sun. The Earth's thermal emitted radiation is mostly in the infrared (or longwave part of the spectrum. The balance between incoming and outgoing energy is called the Earth's radiation budget.

Similarly, a cold surface causes water to condense from the air onto the land or ocean. Latent heat flux is the amount of energy moving from the surface to the air due to evaporation (positive values) or from the air to the land due to condensation (negative values).

The animation clearly shows the evaporation over land only during the heat of the day, while the evaporation over the ocean is continuous throughout the day. The highest positive latent heat flux occurs during hurricanes and typhoons, as these events are powered by the movement of heat energy from the warm ocean to the atmosphere, seen here in Hurricane Frances and Typhoon Songda.

This animation shows the monthly average net radiant flux from July, 2002 through June, 2004 as measured by the CERES instrument. This is the incoming radiation minus the outgoing reflected or thermal energy given off by areas of the Earth. Regions in red and yellow have a net incoming flux and are being heated. Regions in blue have a net outgoing flux and are being cooled. Regions in black are in rough equilibrium. Cloud-free summertime oceans are heated the most, while high latitude winter regions are cooled the most, probably because of the longer winter nights. Note that regions that reflect a lot of sunlight, such as the polar ice sheets and the Sahara desert are almost always in equilibrium or are cooling regions. || ", "hits": 39 }, { "id": 3095, "url": "https://svs.gsfc.nasa.gov/3095/", "result_type": "Visualization", "release_date": "2005-02-01T12:00:00-05:00", "title": "Average Total-sky Incoming Solar Flux (WMS)", "description": "The Earth's climate is determined by energy transfer from the sun to the Earth's land, oceans, and atmosphere.

It is clear from the animation that the most intensive heating occurs in ocean regions with few clouds, while the second most intense are cloud-free regions over vegetated land areas.

As the Earth moves around the sun, the fact that the Earth's axis is tilted means that the sun's overhead position moves from the Northern Hemisphere to the Southern Hemisphere and back from one summer to the next. This effect causes winters to be cold and summers warm in the Northern Hemisphere and the opposite in the Southern Hemisphere. This animation shows the incoming solar irradiance on the Earth at noon on the Greenwich meridian during an entire year, illustrating this movement. The magnitude of this irradiance comes from measurements by the TIM instrument on SORCE. Since the Earth's orbit is elliptical, the magnitude of the solar irradiance at the Earth is least when the Earth is farthest from the sun and greatest when the earth is closest. This 6 or 7 percent change can be seen in the animation by watching the dark bands move. When the bands expand from the bright spot, the Earth is getting closer to the sun, from July through December, and when they contract the Earth is moving away, from January through June. The sun's irradiance is also variable from day to day, but that effect is about ten times smaller than the effect of the earth's orbit. || ", "hits": 60 }, { "id": 20076, "url": "https://svs.gsfc.nasa.gov/20076/", "result_type": "Animation", "release_date": "2003-03-26T12:00:00-05:00", "title": "SORCE Beauty Pass", "description": "A close-up view of the SORCE satellite in orbit. || A close-up view of the SORCE satellite in orbit. || sorce_pre.00002_print.jpg (1024x698) [36.1 KB] || sorce_thm.png (80x40) [3.3 KB] || sorce_pre.jpg (320x218) [4.6 KB] || sorce_pre_searchweb.jpg (320x180) [32.6 KB] || sorce.webmhd.webm (960x540) [3.3 MB] || sorce.mpg (352x240) [5.5 MB] || ", "hits": 13 } ] }
