It will stay in this tandem orbit for about six months while scientists and engineers take a careful look at any differences between Jason-2 and Jason-3. The map shown here was generated using sea surface height measurements from the first 10 days (February 12-20, 2016) of data collected once Jason-3 reached its operational orbit of 830 miles (1336 kilometers). The map corresponds well to data from its predecessor, Jason-2. Higher-than-normal sea levels are red; lower-than-normal sea levels are blue. El Niño is visible as the red blob in the eastern equatorial Pacific. After that, Jason-2 will move to an interleaved orbit (ground tracks halfway between those of Jason-3) where the two missions collectively will provide double the observational coverage of the global ocean. Extending the timeline of ocean surface topography measurements begun by the Topex/Poseidon and Jason-1 and Jason-2 satellites; Jason-3 will make highly detailed measurements of sea-level on Earth to monitor climate change and track phenomena like El Niño. It will also enable more accurate weather, ocean, and climate forecasts, including helping global weather and environmental agencies more accurately forecast the strength of tropical cyclones. || ", "hits": 15 }, { "id": 30756, "url": "https://svs.gsfc.nasa.gov/30756/", "result_type": "Hyperwall Visual", "release_date": "2016-03-08T00:00:00-05:00", "title": "Sea Surface Height Anomaly", "description": "Sea Surface Height Anomaly during the 2015-2016 El Niño || aviso_ssha_20160101_print.jpg (1024x574) [113.0 KB] || aviso_ssha_20160101_searchweb.png (320x180) [54.8 KB] || aviso_ssha_20160101_thm.png (80x40) [4.8 KB] || aviso_ssha_2015-2016_1080p.mp4 (1920x1080) [20.8 MB] || aviso_ssha_2015-2016_720p.mp4 (1280x720) [13.5 MB] || aviso_ssha_2015-2016_720p.webm (1280x720) [6.0 MB] || aviso_ssha_20160101.tif (4104x2304) [4.9 MB] || aviso_ssha_2015-2016_2304p.mp4 (4096x2304) [18.2 MB] || ", "hits": 143 }, { "id": 30629, "url": "https://svs.gsfc.nasa.gov/30629/", "result_type": "Hyperwall Visual", "release_date": "2015-12-27T16:00:00-05:00", "title": "El Niño Watch 2015", "description": "Animation of Sea Surface Height Anomaly for 2015 compared to 1997 || ssha_1997vs2015_print.jpg (1024x574) [142.6 KB] || ssha_1997vs2015_searchweb.png (180x320) [71.4 KB] || ssha_1997vs2015_thm.png (80x40) [7.0 KB] || ssha_1997vs2015_720p.webm (1280x720) [2.4 MB] || ssha_1997vs2015_720p.mp4 (1280x720) [4.0 MB] || ssha_1997vs2015_1080p.mp4 (1920x1080) [5.1 MB] || ssha_1997vs2015_2304p.mp4 (4096x2304) [15.3 MB] || ssha_1997vs2015_360p.mp4 (640x360) [1.7 MB] || ssha_1997vs2015.tif (4104x2304) [4.3 MB] || ssha_1997vs2015_30629.key [7.5 MB] || ssha_1997vs2015_30629.pptx [4.9 MB] || el_nino_1997vs2015_recent_still.hwshow [230 bytes] || ", "hits": 56 }, { "id": 30501, "url": "https://svs.gsfc.nasa.gov/30501/", "result_type": "Hyperwall Visual", "release_date": "2014-05-13T00:00:00-04:00", "title": "Sea Surface Height Anomalies, 1950-2009", "description": "Ocean tide gauges have been used for more than a century to measure sea surface height at specific locations around the globe. Today, scientists combine data from ocean tide gauges with global observations of sea surface height from satellite radar altimeters to detect patterns and monitor changes in ocean height. Currently, NASA’s OSTM/Jason-2 mission—a continuation of the TOPEX/Poseidon and Jason missions—measures the height of the sea surface with an accuracy of about 3 centimeters (just over 1 inch) relative to the center of the Earth. These highly accurate measurements of the height of the sea surface (commonly called “sea level”) are needed to provide long-term information about the world's ocean and its currents. In this visualization, sea surface height anomalies derived from ocean tide gauge data (before 1992) and satellite altimeter data (after 1992) show differences above and below normally observed sea surface heights from 1950 to 2009. These data help show how much heat is stored in the ocean. For example, El Niño events (characterized by warm water and high sea surface height anomalies in the Eastern Pacific) are visible in 1957, 1965, 1972, 1982, 1987, and 1997 along the Equator. Sea surface height data also have many other applications, such as in fisheries management, navigation, and offshore operations. || ", "hits": 36 }, { "id": 30502, "url": "https://svs.gsfc.nasa.gov/30502/", "result_type": "Hyperwall Visual", "release_date": "2014-05-13T00:00:00-04:00", "title": "Sea Surface Height Anomalies, 1992-2011", "description": "Using data from several satellite radar altimeters, a finer picture of the ever-changing height of the ocean is revealed. In this visualization, sea surface height anomalies derived from satellite altimeter data show differences above and below normally observed sea surface heights from 1992 to 2011. Blue shades indicate areas where sea surface height is lower than normal, while red shades indicate areas where sea surface height is higher than normal. Swirling currents called eddies pepper the scene and can be found in every major ocean basin. Near the Equator, ocean eddies give way to fast moving features called Kelvin waves. When they build up in the Pacific, these waves can usher in a phenomenon known as El Niño, which happens when warm water and high sea levels move into the Eastern Pacific along the Equator. Occurring roughly every 3-4 years, El Niño events can have a big impact on weather across the globe, bringing extra rainfall to the American Southwest and even affecting hurricanes in the Atlantic Oceans.
