Abstract

The ERS/ENVISAT (Advanced) Along Track Scanning Radiometer (A)ATSR provides an extremely well characterised and calibrated data set of global coverage high resolution Sea Surface Temperature (SST) observations from 1992 to present. Within the activities of the GODAE/Global High Resolution SST Pilot Project (GHRSST-PP), the (A)ATSR SST time series has been chosen by several international teams as a reference sensor to which other sensor SST data are adjusted for bias. In order to do this with confidence, a new scheme for the characterisation of (A)ATSR bias has been developed and applied to the (A)ATSR data set.

This presentation reviews the requirements for a stable high-resolution SST data set, activities that have been undertaken to use the (A)ATSR record as a reference data set within the GHRSST-PP and the verification and validation work that has been conducted to demonstrate the impact of (A)ATSR for operational global high resolution SST analysis used by ocean, weather and climate forecasting teams.
