Sentinel-3 SLSTR - Level 1B Top-of-Atmosphere Radiance and Brightness Temperature

This collection contains Sentinel-3 Level-1 products derived from the Sea and Land Surface Temperature Radiometer (SLSTR). The data consist of radiances and brightness temperatures for each pixel in a regular image grid, each view and each SLSTR channel, plus annotations data associated with SLSTR pixels. 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.
