Sentinel-3 OLCI Technical Guide - Validation

Validation of Level-1 products includes both radiometric and geometric validation activities. These activities are performed routinely by the Optical Mission Performance Cluster, and more particularly after a new radiometric and/or geometric calibration of the OLCI instrument, after any change of the processing baseline.

Validation of Level-2 products consists in comparing the OLCI products with in-situ measurements (ideally with Fiducial Reference Measurements) or, or, where these do not exist, by comparing the products with other satellite missions (for example, MODIS).

The mission performance assessment, the monitoring of the instrument and the validation results are reported in the OLCI Data Quality Report published monthly and in the Annual Performance Report, whose latest edition is available here.
