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.
