  • This collection contains Sentinel-3 Level-2 Land products derived from the SAR Radar Altimeter (SRAL) and Microwave Radiometer (MWR) instruments. The altimetry products consist of surface topography measurements of the land surface. The Sentinel-3 mission, jointly operated by ESA and EUMETSAT, is designed as a constellation of two identical polar orbiting satellites, separated by 180°, for the provision of long-term operational marine and land monitoring services. Sensor: SRAL (SAR Radar Altimeter), MWR (Microwave Radiometer) Revisit time: <2 days at the equator Launch dates: 16 February 2016 (Sentinel-3A), 25 April 2018 (Sentinel-3B) Archiving start date: 29 February 2016 Mission Status: ongoing Terms and conditions for the use of Sentinel data https://scihub.copernicus.eu/twiki/pub/SciHubWebPortal/TermsConditions/TC_Sentinel_Data_31072014.pdf Sentinel-3 Mission Overview https://sentinel.esa.int/web/sentinel/missions/sentinel-3 Sentinel-3 SRAL/MWR - Level 2 Products Overview and Processing Levels https://earth.esa.int/web/sentinel/technical-guides/sentinel-3-altimetry/level-2-algorithms-products https://earth.esa.int/web/sentinel/user-guides/sentinel-3-altimetry/processing-levels/level-2 Resolutions of Sentinel-3 Altimetry data: https://earth.esa.int/web/sentinel/user-guides/sentinel-3-altimetry/resolutions File format of measurement data: netCDF Suggested software: Broadview Radar Altimetry Toolbox (BRAT) Sentinel-3 Altimetry coverage: https://earth.esa.int/web/sentinel/user-guides/sentinel-3-altimetry/coverage
