The SSHA displayed in the animation is derived from along-track high-pass-filtered SWOT SSH data, which effectively removes long-wavelength errors and large-scale ocean signals. SWOT provides detailed measurements of water elevations across various global water bodies, including open and coastal oceans, rivers, and lakes, making it a true global all-water mission. The data gathered will enhance our understanding of small-scale ocean circulations, the ocean's role in Earth's climate, global hydrological circle, and freshwater management worldwide. || swot_oceans-rivers_00000_print.jpg (1024x576) [147.5 KB] || swot_oceans-rivers_00000.png (3840x2160) [3.8 MB] || swot_oceans-rivers_00000_searchweb.png (320x180) [53.8 KB] || swot_oceans-rivers_00000_thm.png (80x40) [4.3 KB] || swot_2024-06-06-A-HD.mp4 (1920x1080) [65.7 MB] || swot_2024-06-06-A-HD.webm (1920x1080) [14.3 MB] || swot_2024-06-06-A-4K.mp4 (3840x2160) [65.8 MB] || ", "hits": 144 }, { "id": 31232, "url": "https://svs.gsfc.nasa.gov/31232/", "result_type": "Hyperwall Visual", "release_date": "2024-02-26T00:00:00-05:00", "title": "Sea Surface Height Anomaly, 2022-2024", "description": "Animation of Sea Surface Height Anomaly in the Pacific starting January 1, 2022. || nrt_global_allsat_phy_l4_20240207_print.jpg (1024x576) [184.6 KB] || nrt_global_allsat_phy_l4_20240207_searchweb.png (320x180) [63.1 KB] || nrt_global_allsat_phy_l4_20240207_thm.png (80x40) [13.1 KB] || nrt_global_allsat_phy_l4_20220101-20240207_1080p30.mp4 (1920x1080) [35.8 MB] || nrt_global_allsat_phy_l4_20220101-20240207_1080p30.webm (1920x1080) [3.1 MB] || nrt_global_allsat_phy_l4 (3840x2160) [0 Item(s)] || nrt_global_allsat_phy_l4_20220101-20240207_2160p30.mp4 (3840x2160) [91.4 MB] || nrt_global_allsat_phy_l4_20240207.tif (3840x2160) [4.2 MB] || nrt_global_allsat_phy_l4_2022-2024.hwshow [133 bytes] || ", "hits": 348 }, { "id": 31265, "url": "https://svs.gsfc.nasa.gov/31265/", "result_type": "Hyperwall Visual", "release_date": "2023-11-24T00:00:00-05:00", "title": "Global sea surface height by the Surface Water and Ocean Topography (SWOT) mission – the first 21-day cycle", "description": "Rotating globe showing sea surface height anomaly || swot_2023-10-30-A.0001_print.jpg (1024x576) [150.8 KB] || swot_2023-10-30-A.0001_searchweb.png (320x180) [45.9 KB] || swot_2023-10-30-A.0001_thm.png (80x40) [4.2 KB] || swot_2023-10-30-A_1080p60.mp4 (1920x1080) [44.5 MB] || swot_2023-10-30-A_1080p60.webm (1920x1080) [8.1 MB] || swot_2023-10-30-A.0001.tif (5760x3240) [13.9 MB] || swot_2023-10-30-A_2160p60.mp4 (3840x2160) [113.5 MB] || swot_2023-10-30-A_1080p60.hwshow [91 bytes] || ", "hits": 88 }, { "id": 31247, "url": "https://svs.gsfc.nasa.gov/31247/", "result_type": "Hyperwall Visual", "release_date": "2023-09-27T00:00:00-04:00", "title": "SWOT Monitors Warming Waters Off California Coast \nFull Resolution", "description": "This data visualization image above shows sea surface heights off the northern California coast in August 2023 as measured by the Surface Water and Ocean Topography (SWOT) satellite. || SWOT_2023-08_ca_coast_PIA26091_print.jpg (1024x576) [81.4 KB] || SWOT_2023-08_ca_coast_PIA26091.png (3840x2160) [2.2 MB] || SWOT_2023-08_ca_coast_PIA26091_searchweb.png (320x180) [29.9 KB] || SWOT_2023-08_ca_coast_PIA26091_thm.png (80x40) [3.4 KB] || SWOT_2023-08_ca_coast_PIA26091.hwshow || ", "hits": 25 }, { "id": 31174, "url": "https://svs.gsfc.nasa.gov/31174/", "result_type": "Hyperwall Visual", "release_date": "2022-01-28T15:00:00-05:00", "title": "Sea Surface Height Anomaly from Sentinel-6 MF", "description": "Along Track Sea Surface Height Anomaly data from Sentinel-6 MF are shown with rolling 10-day coverage in daily increments from December 7, 2020 to September 24, 2021.

After launch, Jason-3 was maneuvered into orbit about 80 seconds behind Jason-2, where it collected data at essentially the same time and place. 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": 21 }, { "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": 69 }, { "id": 11003, "url": "https://svs.gsfc.nasa.gov/11003/", "result_type": "Produced Video", "release_date": "2012-06-19T00:00:00-04:00", "title": "Excerpt from \"Dynamic Earth\"", "description": "A giant explosion of magnetic energy from the sun, called a coronal mass ejection, slams into and is deflected completely by the Earth's powerful magnetic field. The sun also continually sends out streams of light and radiation energy. Earth's atmosphere acts like a radiation shield, blocking quite a bit of this energy.Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine — the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles — all in an attempt to equalize temperatures around the world.A jury appointed by the National Science Foundation (NSF) and Science magazine has selected \"Excerpt from Dynamic Earth\" as the winner of the 2013 NSF International Science and Engineering Visualization Challenge for the Video category.
