FIDUCEO project: Product User Guide – Ensemble Sea and Lake Surface Temperature

This document describes the Ensemble Sea and Lake Surface Temperature(ST) climate data record (CDR) created by the FIDUCEO project in August 2019 with version designation v0.20. The released data record is based on the MetOp-A Advanced Very High Resolution Radiometer (AVHRR)"easy" FCDR (fundamentalCDR) version 1.0, with additional ST optimisation of the brightness temperature calibration coefficients. The ST CDR is a gridded dataset (level 3 uncollated) at 0.05°latitude-longitude resolution. This product user guide gives: 1. An overview of the specifications of the ST CDR; 2. A high-level description of the implementation of the retrieval processing chain; 3. Information on limitations of this current version of the data record; 4. Technical details on the format and on how to access the data
