The main objective of the SENTINEL-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring. This collection represents the Level-1 and Level-2 Full OLCI products. These products include Top-Of-Atmosphere (TOA) radiometric measurements, radiometrically corrected, calibrated and spectrally characterised. It is quality controlled, ortho-geolocated (latitude and longitude coordinates, altitude) and annotated with satellite position and pointing, landmarks and preliminary pixel classification (e.g. land/water/cloud masks). Products are generated in FR (300 m) for the whole globe with the same coverage. This collection also provides SAR Radar Altimeter (SRAL) level-1 products and land products level-2 (SR_2_LAN) products and SLSTR products.
