When the solar wind encounters Earth, it is deflected by our planet's magnetic shield, causing most of the solar wind's energetic particles to flow around and beyond us.

Above the troposphere is the stratosphere, which reaches up to around 31 miles. It contains the ozone layer, which absorbs harmful ultraviolet (UV) radiation from the Sun. Next is the mesosphere, which extends from about 31 to 53 miles above Earth. It is the coldest layer of the atmosphere, and it is where most meteors burn up upon entering. Above the mesosphere is the thermosphere, ranging from about 53 to 375 miles above Earth. Known as the upper atmosphere, this region contains the ionosphere, a region filled with charged particles that enable radio communications and where auroras often occur. The outermost layer is the exosphere, which gradually transitions into outer space. It is extremely thin and composed mainly of hydrogen and helium.

Sunlight reflects off Earth’s surface, and scientists identify the land cover based on which wavelengths are reflected strongly or weakly.But sunlight is also reflected by particles in the atmosphere, which distorts the data and can lead to what looks like a haze in the imagery. Using basic principles of physics, and knowing the meteorological conditions, scientists can determine the effects of the scattering and absorption as light passes through the atmosphere. This atmospheric correction is essential to determining exactly how much of each wavelength reflected of the features of the surface, and having quantifiable data.The videos below show different examples of atmospheric scattering which need to be accounted for when doing atmospheric correction of satellite data. In these cases, it is for observations over water. The resulting atmospheric corrections are part of the process for the new Landsat Aquatic Reflectance data product.

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": 163 }, { "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": 258 }, { "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": 44 }, { "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": 65 }, { "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": 114 }, { "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": 73 }, { "id": 4762, "url": "https://svs.gsfc.nasa.gov/4762/", "result_type": "Visualization", "release_date": "2019-12-10T17:30:00-05:00", "title": "GOLD Instrument observes the July 2019 Total Solar Eclipse", "description": "Comparative visualizations of Earth in visible light and the ultraviolet emission of oxygen recombining from ions.

Most are familiar with the beloved images of the blue marble or pale blue dot — Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the nearest region of space, you might encounter an unfamiliar sight. 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. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by day-to-day solar radiation. || ", "hits": 372 }, { "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.

By combining NASA’s observations and chemistry simulations we have a clearer view of the evolution of Earth’s ozone layer over the recent past. || oman_toz_2002_pngs_1080.00001_print.jpg (1024x576) [117.1 KB] || oman_toz_2002_pngs_1080.00001_searchweb.png (320x180) [61.2 KB] || oman_toz_2002_pngs_1080.00001_web.png (320x180) [61.2 KB] || oman_toz_2002_pngs_1080.00001_thm.png (80x40) [6.0 KB] || oman_toz_2002_pngs_1080.webm (1920x1080) [10.5 MB] || oman_toz_2002_pngs_1080.mp4 (1920x1080) [187.7 MB] || ", "hits": 143 }, { "id": 4583, "url": "https://svs.gsfc.nasa.gov/4583/", "result_type": "Visualization", "release_date": "2017-11-20T10:00:00-05:00", "title": "NASA's Near-Earth Science Mission Fleet: March 2017", "description": "NASA Near-Earth Science Fleet (August 2017) || near_earth_sciences02.6100_print.jpg (1024x576) [69.3 KB] || near_earth_sciences02.6100_searchweb.png (320x180) [44.2 KB] || near_earth_sciences02.6100_thm.png (80x40) [4.0 KB] || near_earth_sciences02_1080p60.mp4 (1920x1080) [51.2 MB] || 1920x1080_16x9_60p (1920x1080) [0 Item(s)] || near_earth_sciences02_1080p60.webm (1920x1080) [12.6 MB] || near_earth_sciences02_360p30.mp4 (640x360) [6.6 MB] || 9600x3240_16x9_30p (9600x3240) [0 Item(s)] || ", "hits": 29 }, { "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": 79 }, { "id": 11937, "url": "https://svs.gsfc.nasa.gov/11937/", "result_type": "Produced Video", "release_date": "2017-07-20T08:00:00-04:00", "title": "Earth's Energy Budget", "description": "Earth's energy budget is a metaphor for the delicate equilibrium between energy received from the Sun versus energy radiated back out in to space.

To determine a star’s habitable zone, scientists have traditionally considered how much heat the star emits. Stars more massive than our sun produce more heat and light, so the habitable zone must be farther out.

What is Rad-X, why is it important, and what is the EPO and project scientist's role?NASA's Radiation Dosimetry Experiment, or RaD-X, is a low-cost, high-altitude balloon project. Its mission is to help us understand and quantify cosmic ray exposure at the top of atmosphere. That's the zone where commercial airlines fly. This is important because these cosmic rays are a primary source of ionizing radiation in the atmosphere and increase the risk of cancer and other health impacts. A pilot absorbs as much radiation as a worker in a nuclear power plant, yet the dose of radiation they receive during a cosmic storm or during the span of their career is not quantified or documented.The RaD-X payload consists of four radiation sensors that are used to measure incoming radiation. The RaD-X payload was launched on September 25, 2015 via a high-altitude research balloon. This supplements NASA's Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS) model, which helps us make informed decisions about radiation exposure safety for flight crews, the general public, and commercial space operations. RaD-X also supported Cubes in Space on their inaugural balloon flight, which carried various science projects from schools across the U.S. Cubes in Space is a global design contest in which teams of secondary school students from around the world develop unique science experiments for launch into the upper atmosphere. During the 24-hour mission, the RaD-X payload and Cubes in Space experienced altitudes above 100,000 ft. during the day and above 60,000 ft. during the night. On RaD-X, I had dual roles. First as the Project Scientist it was my job to serve as an interface between the scientists and engineers. Essentially, to help them speak the same language and communicate effectively. I was also the EPO lead. This included coordinating school visits, developing fact sheets, and interfacing with NASA Langley Research Center’s public affairs and communications.How do you use Earth visualizations? Does it have applications to the Rad-X project?Using data from the NAIRAS model, we create visualizations of predicted radiation exposure at multiple altitudes. These show exposure rates at aircraft levels and a vertical profile on global exposure rates. Now that we have successfully launched the Rad-X mission, we have started to analyze real data. During the launch we monitored (in real-time) how the measurements compared with the model predicted values from NAIRAS. Creating visualizations in real-time made the comparisons easier to interpret. || ", "hits": 18 }, { "id": 4377, "url": "https://svs.gsfc.nasa.gov/4377/", "result_type": "Visualization", "release_date": "2015-10-02T16:00:00-04:00", "title": "A 3-D Look at Weather, Clouds, and Aerosols", "description": "This gallery was created for Earth Science Week 2015 and beyond.

Think about it: even though we don't see it, above us is a great aerial ocean! Over time my fascination has grown from weather maps and pondering the origins of storms, to learning all about the physics that surround our everyday lives. From as early as grade school I was also very interested in computers: diagnosing errors, developing programming skills and learning all about hardware and operating systems. So you might say my interests naturally led me to a career as a NASA scientist, where I create visualizations to study the underlying factors that drive weather patterns. Visualizations help us to see the world differently and actively.Many of you have no doubt seen your homes from space using a program called Google Earth™. But did you know you could do a lot more with the right data? In fact I often use it to map atmospheric data in three-dimensions (3-D) around the globe. But one of the challenges I often face is that data comes from many different sources, such as NASA and NOAA satellites or ground-observation stations. This means the data is stored on computer disks all over the country and are named and organized according to different standards, requiring us to customize techniques for producing accurate visualizations in one, 3-D display of the Earth. We do this in order to analyze atmospheric relationships more easily because many weather phenomena arise from physical interactions, both horizontally and vertically, in the global circulation.A big part of atmospheric research relies on using computer models to simulate what our atmosphere will do under different conditions. A great example of this is the data used to prepare the daily weather forecast. This data originates from weather forecasting models that calculate atmospheric motions using the world’s fastest supercomputers. But how do we know these forecasts are accurate? Researchers can verify a model's performance by visualizing one of the variables such as temperature, humidity, wind speed, wind direction, or air pressure and then using color shading, contour curves, and wind \"barbs\" to graph that data. Then they overlay the observations from NASA satellites such as cloud-top imagery, cloud-top temperature, and vertical distributions of clouds and aerosols, with the graph (it can be challenging to synchronize the data display as these times usually don't match). After this process, the display confirms the model's accuracy. This method is used to study many atmospheric events, such as timing of a storm system, precipitation, or the direction of dust or smoke transport. || ", "hits": 89 }, { "id": 4365, "url": "https://svs.gsfc.nasa.gov/4365/", "result_type": "Visualization", "release_date": "2015-09-30T12:00:00-04:00", "title": "Airborne in the Arctic", "description": "This gallery was created for Earth Science Week 2015 and beyond.

After extensive pre-flight configurations, our science payload is primed for our eight-hour mission. Without delay, the engines’ roar becomes a howl as we hurtle down the nearly three-mile stretch of runway until that near-weightless moment we become airborne. Our mission into the clouds of the arctic is underway.Clouds are important drivers of Earth’s climate by regulating the amount of sunlight that is absorbed at the ground versus what is reflected back into space. You’ve probably experienced this firsthand when sitting outside on a hot and sunny summer day when a fluffy cumulus cloud crosses the sky between you and the sun. The respite that you feel from the heat of the sun’s rays means that that energy is no longer reaching you at the surface. At the lower latitudes where most of us live, these thick, stratiform and cumuliform clouds have a cooling effect because the white cloud reflects the sun’s energy back to space instead of being absorbed by the dark brown soil, green trees and plants, or the blue ocean waters. The story is much more complicated at the high latitudes where the frozen ice surface is also very bright white and reflective. Under these conditions, clouds can actually have a net warming effect because they reflect a similar or smaller amount of the incoming sunlight, but also trap more of the outgoing heat radiation and keep it close to the surface (like a blanket.)The exact balance between heating and cooling depends on the cloud properties - droplet number and size - and where the clouds are located in the atmosphere (high or low altitude as well as overlying dark water or bright ice.) Unraveling these effects is important for understanding how the Earth’s radiation balance and climate exist now and how they are likely to change in the future.Differentiating the impacts of low-level clouds versus Arctic sea ice on sunlight from space is hard, because to a passive satellite sensor orbiting many hundreds of kilometers above the Earth’s surface, both the ice and cloud look very similar. To best visualize this system, we must go to the Arctic with scientific research aircraft to measure the cloud properties just below, above, and within the clouds themselves. This was precisely the motivation behind the NASA Arctic Radiation – IceBridge Sea and Ice Experiment (ARISE), which was conducted in the Alaskan Arctic from September-October, 2014.ARISE carried out 14 science flights aboard the NASA Wallops Flight Facility C-130 Hercules aircraft, which was outfitted with a comprehensive suite of scientific instrumentation including a laser altimeter for measuring the sea ice surface properties, in situ cloud probes, and a sun photometer and two radiometers (SSFR, BBR) for measuring the surface, aerosol, and cloud radiative properties. An example 8-hour flight track is shown for the September 7th science flight in the Google Map below. The aircraft was based at Eielson Air Force Base near Fairbanks, AK, and began each flight by transiting approximately 2 hours north to the vicinity of the ice edge in the Beaufort Sea. On the 7th, the aircraft flew a series of parallel, horizontal legs to cover a single satellite grid box of the overflying NASA Clouds and the Earth's Radiant Energy System (CERES) satellite. These measurements help CERES scientists to understand how small-scale variability in ice and cloud extent and properties affect their satellite-based retrievals.

Before wrapping up the research flight on the 7th and beginning our 2-hour transit back to Fairbanks, we descended into the low-level clouds to measure their microphysical properties with the in situ cloud probes. The video below shows what it’s like to measure an Arctic cloud from inside it!

But until recently, scientists rarely considered the effect of all three major types of light-absorbing aerosols together in climate models.In a new study, NASA scientists used a climate model to examine the impact of this snow-darkening phenomenon on Northern Hemisphere snowpacks, including how it affects snow amount and heating on the ground in spring.The study looked at three types of light-absorbing aerosols – dust, black carbon and organic carbon. 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. They found that the aerosols indeed played a role in absorbing more of the sun’s energy. 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. Black carbon’s snow darkening effect had a larger impact primarily in Europe, the eastern Himalayas and East Asia. It had a smaller impact in North America. Organic carbon’s snow darkening effect was relatively lower but present in regions such as southeastern Siberia, northeastern East Asia and western Canada.“As we add more of these aerosols to the mix, we are potentially increasing our overall impact on Earth’s climate,” said research scientist Teppei Yasunari at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.Research: Impact of snow darkening via dust, black carbon, and organic carbon on boreal spring climate in the Earth systemJournal: Geophysical Research: Atmospheres, June 15, 2015.Link to paper: http://onlinelibrary.wiley.com/doi/10.1002/2014JD022977/fullHere is the YouTube video. || ", "hits": 117 }, { "id": 30604, "url": "https://svs.gsfc.nasa.gov/30604/", "result_type": "Hyperwall Visual", "release_date": "2015-06-28T00:00:00-04:00", "title": "CERES Radiation Fluxes", "description": "These maps show monthly reflected-shortwave radiation from March 2000 to the present from the Energy Balanced and Filled (EBAF) data product.

Placed in an orbit that allows their perspective to changed over the eight years since their launch in 2008 (ck), the satellites are about to enter a new phase of their journey: a time when the bright light and heat of the sun will stand in the way of sending data back to Earth.This phase is a direct result of the orbits for STEREO, which is short for the Solar Terrestrial Relations Observatory. The spacecraft travel at different speeds. This means that over time, the satellites become increasingly out of sync, appearing from Earth's perspective to drift farther apart, able to observe first the sides and eventually the far side of the sun. For the first time ever, thanks to STEREO and near-Earth solar telescopes such as NASA’s Solar Dynamics Observatory the human race has had its first 360-degree view of the sun.The orbits have continued to cause the STEREO spacecraft's position to change, however, and now they are nearing each other once again, this time on the other side of the sun. During this period when the sun blocks Earth's view — a geometrical position known in astronomy as a superior conjunction — radio receivers on Earth will not be able to distinguish STEREO's signal from the sun's radiation. Communication with the spacecraft will cease and the satellites will both go into safe mode without collecting data for a time. This will happen for STEREO-Ahead from March 24 to July 7, 2015. STEREO-Behind will be in superior conjunction from Jan. 22 to March 23, 2015. At least one spacecraft, therefore, will always be collecting data. Before this occurs, the heating from the sun will also begin to affect – though not shut down — data collection. From wherever they are in space, the STEREO spacecraft aim their antenna toward Earth to send down data. This position puts the antenna fairly close to pointing at the sun, exposing the instruments to more heat than it can safely bear. The antenna can be adjusted to point in different directions, but the signal coming to Earth will be much fainter and won't allow for as much data to be downloaded. This antenna adjustment will begin on Aug. 20, 2014, for the STEREO-Ahead spacecraft and on Dec. 1, 2014, for STEREO-Behind. During this phase, STEREO instruments will continue to run 24 hours a day, but they will gather lower-resolution data than usual. Some of this data will be downloaded whenever STEREO can link up with an Earth receiver. The rest of the data will be stored on board to be downloaded when the spacecraft reach a more auspicious geometrical position in early 2016. To test for this off-pointing from the sun, STEREO-Ahead will undergo tests and not be collecting data from July 6-12, 2014. The same tests will be performed on STEREO-Behind from Sept. 29 – Oct. 6, 2014. Throughout this entire phase until 2016, at least one STEREO spacecraft will be capturing data at any one time, so scientists will have an uninterrupted record of events on the sun to coordinate with the observations of solar telescopes on the Earth side. Real time monitoring of the sun, its flares and coronal mass ejections – information used by the US National Oceanic and Atmospheric Administration to help forecast space weather — will also continue via a fleet of NASA spacecraft closer to Earth. || ", "hits": 32 }, { "id": 10936, "url": "https://svs.gsfc.nasa.gov/10936/", "result_type": "Produced Video", "release_date": "2014-05-29T09:55:00-04:00", "title": "GOES-R Series Resource Reel", "description": "The new generation GOES-R satellites will carry significant improvements and technology innovation on board.

Other kinds of energy are invisible, like the energy that makes our hands feel warm when we hold them over a fire, or the energy that cooks our food in the microwave. When Earth absorbs sunlight, it heats up. The heat, or \"outgoing longwave radiation,\" radiates back into space. Satellites measure this radiation as it leaves the top of Earth's atmosphere. The hotter a place is, the more energy it radiates. These maps show monthly outgoing longwave 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 show the amount of outgoing longwave radiation leaving Earth's atmosphere (in Watts per square meter). Bright yellow and orange indicate greater heat emission, purple and blue indicate intermediate emissions, and white shows little or no heat emission. || ", "hits": 209 } ] }
