As El Niño changed global weather patterns Southern Africa went into severe drought. On top of already dry conditions, the region experienced its lowest rainfall in 35 years.With the Soil Moisture Active Passive (SMAP) mission, launched in 2015, NASA has dedicated soil moisture measurements for the first time – and could see this severe drought emerging. SMAP's highly sensitive microwave radiometer detects the energy emitted by soil depending on how wet or how dry it is. The old gardener's trick is to squeeze a handful of dirt in your hand and see whether it clumps or falls apart. Think of SMAP doing the same thing – with a lot more precision, all around the world, every 3 days.SMAP allowed us to see a connection between Pacific Ocean water temperatures and the moisture of the soil in Southern Africa. These measurements are now being put to operational use more than ever. SMAP's data was fed into the USDA's global crop yield forecasts – the Foreign Agriculture Service reports that help drive multi-billion dollar commodity markets around the world. In fact, the Foreign Ag Service scientist for this region said that with SMAP they now have the first reliable soil moisture data in 30 years.As crops failed and soils were left bare, we used the Terra and Aqua satellites to assess these effects on the vegetation from a local to regional scale. The Normalized Differential Vegetation Index (NDVI) reflects the health of vegetation on the land surface.As this drought spread across Southern Africa, nearly 30 million people were at risk of drastic food shortages. Four out of 10 people did not have access to clean drinking water.The analyses and data provided by NASA scientists are also critical to a USAID program called the Famine Early Warning Systems Network. As food crises arise, the global view provided by NASA scientists informs decisions about where governments and relief agencies should send help.In Southern Africa in 2015 and 2016, nearly 350 million dollars of emergency water and food aid were delivered, in part based on NASA data, to aid millions of people.As the peak of the drought hits in January 2016, the animations show the low soil moisture conditions in Zambia, Zimbabwe, and Botswana. Correspondingly the low vegetation appears in that region as well. || ", "hits": 53 }, { "id": 12254, "url": "https://svs.gsfc.nasa.gov/12254/", "result_type": "Produced Video", "release_date": "2016-06-23T11:00:00-04:00", "title": "Life of the Monsoon", "description": "Additional footage: pond5.comMusic: Ruminations by Miriam Cutler, 24 Dimensions by Christian Telford, David Travis Edwards, Matthew St. Laurent, and Robert Anthony NavarroComplete transcript available.Watch this video on the NASA Goddard YouTube channel. || life_monsoon_still_print.jpg (1024x578) [133.9 KB] || life_monsoon_still_searchweb.png (320x180) [94.5 KB] || life_monsoon_still_thm.png (80x40) [9.4 KB] || 12254_Life_of_the_Monsoon_prores.mov (1920x1080) [7.6 GB] || 12254_Life_of_the_Monsoon.mpeg (1280x720) [933.1 MB] || 12254_Life_of_the_Monsoon_appletv.m4v (1280x720) [141.4 MB] || 12254_Life_of_the_Monsoon_youtube_hq.mov (1920x1080) [2.3 GB] || 12254_Life_of_the_Monsoon.webm (960x540) [112.9 MB] || 12254_Life_of_the_Monsoon_large.mp4 (1920x1080) [282.0 MB] || 12254_Life_of_the_Monsoon_appletv_subtitles.m4v (1280x720) [141.5 MB] || LifeMonsoon.en_US.srt [5.1 KB] || LifeMonsoon.en_US.vtt [5.1 KB] || 12254_Life_of_the_Monsoon_ipod_sm.mp4 (320x240) [49.6 MB] || ", "hits": 59 }, { "id": 12225, "url": "https://svs.gsfc.nasa.gov/12225/", "result_type": "Produced Video", "release_date": "2016-06-02T09:50:00-04:00", "title": "Details of Arctic Greening in North America", "description": "NASA scientists used almost 30 years of data from the NASA/USGS Landsat satellites to track changes in vegetation in Alaska and Canada.

The name equinox comes from the Latin words for \"equal\" (aequus) and \"night\" (nox). The length of day and night is the same on this date: 12 hours each.1. Looking at the Northern Hemisphere, night is on the left and day is on the right.2. Advancing towards December, the Northern Hemisphere night becomes longer and days become shorter. Shorter days mean less solar energy and consequently colder days.3. It is the relative tilt of Earth as it goes around the sun that causes the seasons.TAG: By Dec. 21, 2015, Earth’s North Pole will be tilted 23.5 degrees away from the sun.NOTE: Time-lapse video assembled from images taken by EUMESAT's Meteosat-9 satellite in 2010 and 2011.

For most of the world's oceans, the most important things that influence its color are phytoplankton. Phytoplankton are very small, single-celled plants, generally smaller than the size of a pinhead that contain a green pigment called chlorophyll. All plants (on land and in the ocean) use chlorophyll to capture energy from the sun and through the process known as photosynthesis convert water and carbon dioxide into new plant material and oxygen. Although microscopic, phytoplankton can bloom in such large numbers that they can change the color of the ocean to such a degree that we can measure that change from space. The basic principle behind the remote sensing of ocean color from space is this: the more phytoplankton in the water, the greener it is...the less phytoplankton, the bluer it is.

Though nothing conclusive can yet be determined, it is possible that the detected methane was either produced by geologic processes such as the oxidation of iron (serpentinization) or by microscopic Martian life below the planet's surface. The methane released today could be produced currently, or it could be ancient methane trapped in ice 'cages' called clathrates or as gas below a sub-surface ice layer. || ", "hits": 93 }, { "id": 3571, "url": "https://svs.gsfc.nasa.gov/3571/", "result_type": "Visualization", "release_date": "2008-12-18T00:00:00-05:00", "title": "AMSR-E Arctic Sea Ice: 2005 to 2008", "description": "Sea ice is frozen seawater floating on the surface of the ocean.
