Minimize SLSTR Validation

The Land Validation Report for the release of Sentinel-3 Sea and Land Surface Temperature Radiometer (SLSTR) Level-2 Land Surface Temperature products (SL_2_LST) is available. The report describes the validation of SL_2_LST against in situ observations (Category-A validation), and intercomparison (Category-C validation) of the SL_2_LST product with respect to three independent reference products from the ESA DUE GlobTemperature Project (MODIS, GOES, and SEVIRI).

The results of the validation (Category-A) against in situ observations from "Gold Standard" stations show the SL_2_LST product to have an accuracy for all matchups of 0.94 K, thus meeting the overall mission requirement (S3-MR-420) of < 1 K. Intercomparison (Category-C) with respect to other reference products show differences are around 1 K overall.
