This key indicator of the climate system describes the delicate and complex balance between how much of the sun’s energy reaching Earth is absorbed and how much thermal infrared radiation is emitted back to space. “Absorbed solar radiation fuels the climate system and life on our planet,” said Norman Loeb, CERES Principal Investigator. “The Earth sheds heat by emitting outgoing radiation.” || ", "hits": 253 }, { "id": 4794, "url": "https://svs.gsfc.nasa.gov/4794/", "result_type": "Visualization", "release_date": "2020-02-21T08:00:00-05:00", "title": "CERES Radiation Balance", "description": "The Clouds and the Earth’s Energy Radiant System (CERES) instrument is a key component of NASA’s Earth Observing System, with six active CERES instruments on satellites orbiting Earth and taking data.  For Earth’s temperature to be stable over long periods of time, absorbed solar and emitted thermal radiation must be equal. 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": 151 }, { "id": 30370, "url": "https://svs.gsfc.nasa.gov/30370/", "result_type": "Hyperwall Visual", "release_date": "2013-10-24T12:00:00-04:00", "title": "Monthly Reflected Shortwave Radiation", "description": "If you look at Mars in the night sky, the planet is little more than a glowing dot. From Mars, Earth would have the same star-like appearance. What gives the planets this light? Do they shine like a star? No. The light is mostly reflected sunlight. These images show how much sunlight Earth reflects. Bright parts of Earth like snow, ice, and clouds, reflect the most light; dark surfaces, like the oceans, reflect less light. Earth's average temperature is determined by the balance between how much sunlight Earth reflects, how much it absorbs, and how much heat it gives off. These maps show monthly reflected-shortwave radiation from July 2006 to the present, from the Fast Longwave And Shortwave Radiative Fluxes, or FLASHFlux, Time Interpolation and Spatial Averaging (TISA) data product. The product contains daily observations collected by the Clouds and the Earth's Radiant Energy System (CERES) sensors on NASA's Aqua and Terra satellites. The colors in the map show the amount of shortwave energy (in Watts per square meter) that was reflected by the Earth system. The brighter, whiter regions show where more sunlight is reflected, while green regions show intermediate values, and blue regions are lower values. || ", "hits": 71 }, { "id": 40060, "url": "https://svs.gsfc.nasa.gov/gallery/solar-influence/", "result_type": "Gallery", "release_date": "2010-03-04T00:00:00-05:00", "title": "Solar Influence", "description": "No description available.", "hits": 17 }, { "id": 10389, "url": "https://svs.gsfc.nasa.gov/10389/", "result_type": "Produced Video", "release_date": "2009-02-19T00:00:00-05:00", "title": "Aerosols Absorb; Aerosols Reflect", "description": "Some aerosol particles primarily reflect solar radiation and cool the atmosphere, and others can also absorb radiation and warm the surrounding air.

In these regions, surface temperatures remain below freezing for a portion of each year. Since ice and snow exist relatively close to their melting point, they frequently change from solid to liquid and back again due to fluctuations in surface temperature. Although direct measurements of the cryosphere can be difficult to obtain due to the remote locations of many of these areas, using satellite observations scientists monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.This animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The animation begins in Antarctica, showing ice thickness ranging from 2.7 to 4.8 kilometers thick along with swaths of polar stratospheric clouds. In a tour of this frozen continent, the animation shows some unique features of the Antarctic landscape found nowhere else on earth. Ice shelves, ice streams, glaciers, and the formation of massive icebergs can be seen. A time series shows the movement of iceberg B15A, an iceberg 295 kilometers in length which broke off of the Ross Ice Shelf in 2000. Moving farther along the coastline, a time series of the Larsen ice shelf shows the collapse of over 3,200 square kilometers ice since January 2002. As we depart from the Antarctic, we see the seasonal change of sea ice and how it nearly doubles the size of the continent during the winter.From Antarctica, the animation travels over South America showing areas of permafrost over this mostly tropical continent. We then move further north to observe daily changes in snow cover over the North American continent. The clouds show winter storms moving across the United States and Canada, leaving trails of snow cover behind. In a close-up view of the western US, we compare the difference in land cover between two years: 2003 when the region received a normal amount of snow and 2002 when little snow was accumulated. The difference in the surrounding vegetation due to the lack of spring melt water from the mountain snow pack is evident.As the animation moves from the western US to the Arctic region, the areas effected by permafrost are visible. In December, we see how the incoming solar radiation primarily heats the Southern Hemisphere. As time marches forward from December to June, the daily snow and sea ice recede as the incoming solar radiation moves northward to warm the Northern Hemisphere.Using satellite swaths that wrap the globe, the animation shows three types of instantaneous measurements of solar radiation observed on June 20, 2003: shortwave (reflected) radiation, longwave (thermal) radiation and net flux (showing areas of heating and cooling). Correlation between reflected radiation and clouds are evident. When the animation fades to show the monthly global average net flux, we see that the polar regions serve to cool the global climate by radiating solar energy back into space throughout the year.The animation shows a one-year cycle of the monthly average Arctic sea ice concentration followed by the mean September minimum sea ice for each year from 1979 through 2004. A red outline indicates the mean sea ice extent for September over 22 years, from 1979 to 2002. The minimum Arctic sea ice animation clearly shows how over the last 5 years the quantity of polar ice has decreased by 10 - 14% from the 22 year average.While moving from the Arctic to Greenland, the animation shows the constant motion of the Arctic polar ice using daily measures of sea ice activity. Sea ice flows from the Arctic into Baffin Bay as the seasonal ice expands southward. As we draw close to the Greenland coast, the animation shows the recent changes in the Jakobshavn glacier. Although Jakobshavn receded only slightly from 1042 to 2001, the animation shows significant recession over the past three years, from 2002 through 2004.This animation shows a wealth of data collected from satellite observations of the cryosphere and the impact that recent cryospheric changes are making on our planet.For more information on the data sets used in this visualization, visit NASA's EOS DAAC website. || ", "hits": 104 }, { "id": 3175, "url": "https://svs.gsfc.nasa.gov/3175/", "result_type": "Visualization", "release_date": "2005-06-21T00:00:00-04:00", "title": "Outgoing Shortwave Flux Compared to Clouds (WMS)", "description": "The Earth's climate is determined by energy transfer from the sun to the Earth's land, oceans, and atmosphere.

The impact of these particles on atmospheric molecules causes the molecules to emit light, which forms the visible aurora. This visualization shows the development of the aurora over the North Pole for about three hours on April 17, 1999, as seen by the ultraviolet VIS Earth Camera on the POLAR spacecraft. The two main features of these ultraviolet images are the very bright ultraviolet emission from the reflected solar radiation on the dayside of the Earth and the bright ring of the auroral oval circling the North Pole. The aurora seen in this visualization is the diffuse aurora, a very large bright band that is actually too dim to be seen well from the ground by the human eye. What we normally think of as the aurora are the even brighter curtains of light within the diffuse auroral caused by very energetic electrons. These curtains are too small to be seen in this image. The diffuse aurora appears as a ring around the pole rather than as a bright spot over the entire pole because the solar particles actually spend extended time wandering about within the Earth's magnetic field before traveling down a very select set of magnetic field lines to the Earth. Near the end of this three hour period, the spacecraft was getting so close to the Earth that the edges of the globe were outside the camera's image, which accounts for the growing circular data gaps over Asia and the Pacific Ocean. || ", "hits": 28 }, { "id": 2328, "url": "https://svs.gsfc.nasa.gov/2328/", "result_type": "Visualization", "release_date": "2001-12-12T12:00:00-05:00", "title": "Terra/CERES View of the Earth", "description": "Data sets from the Terra/CERES instrument || Outgoing Longwave Radiation (Average May 11-25, 2000) || ceres_olr_20010511_25_avg.jpg (1800x1098) [414.4 KB] || ceres_olr_20010511_25_avg_web.jpg (320x195) [12.7 KB] || ceres_olr_20010511_25_avg_thm.png (80x40) [5.5 KB] || ceres_olr_20010511_25_avg_web_searchweb.jpg (320x180) [89.5 KB] || ceres_olr_20010511_25_avg.tif (1800x1098) [941.4 KB] || ", "hits": 14 }, { "id": 2156, "url": "https://svs.gsfc.nasa.gov/2156/", "result_type": "Visualization", "release_date": "2001-06-20T12:00:00-04:00", "title": "One Year of Terra/CERES Data (Reflected Solar Radiation) Daily Data", "description": "This animation displays a little over one year of Terra/CERES data (March 1, 2000 to May 25, 2001) at one day resolution.
