Abstract / Description of output

The aim of the (A)ATSR re-analysis for climate project is to derive a homogeneous record of SST covering 1991 to 2007 from the observations of the series of three ATSR radiometers. One feature of the existing (A)ATSR record that could be improved is the high cloud-clearing false alarm rate produced by the large-scale spatial coherence and histogram tests. To address this issue, a new scheme using Bayesian inversion to detect cloud will be applied. A summary of the validation of the Bayesian inversion code is presented, and the application of the method to (A)ATSR imagery is discussed. A comparison is made between the cloud mask generated using the Bayesian scheme and the operational open-ocean cloud-mask.
