BESST project

Inter-sensor Bias Estimation in Sea Surface Temperature

BELSPO project SR/12/158

Context and Objectives

Climate studies need long-term data sets of homogeneous quality, in order to discern trends from other physical signals present in the data and to minimise the contamination of these trends by errors in the source data. Satellite data have proved as very valuable, and we count now on more than 25 years of data for variables like sea surface temperature (SST).

In order to obtain data sets valid for climate research, it is necessary to develop or improve techniques to homogenise data coming from different satellites, as biases exist between them due to their technical characteristics and the changing physical properties of the measured environments.

The specific objectives of this project are:
