This report describes results from the Eumetsat study "Optimal Estimation Method retrievals with IASI, AMSU and MHS measurements". The objectives of the study are to specify a configuration to make joint use of IASI, AMSU and MHS measurements in retrievals based on the optimal estimation method (OEM). The study characterises the added value of using MW and IR radiances in synergy for the retrievals of water vapour and temperature in cloud-free scens with the OEM in comparison to using IASI radiances only, and will also explore the potential of the method for cloudy scenes. Furthermore, the study shall characterise the impact of the loss of one or more AMSU channels.
