The FIDUCEO AVHRR FCDR for MetOp-A has updated calibration parameters which have been harmonised using SNO (Simultaneous Nadir Overpass) matches using the AATSR as a reference as well as corrections for some of the dominant error sources. The Ensemble version has had corrections to two of the calibration parameters (this bias term and the emissivity correction term) to improve SSTs retrieved using the FIDUCEO brightness temperatures when compared to the drifting buoy network. It therefor has mixed references, one a satellite reference and another a virtual reference consisting of radiative transfer modelled brightness temperatures derived using the SST in-situ reference data.
