Radar and lidar (Janiskova/DiMichele/Martins) Preparing for EarthCARE using CloudSat and Calipso Testing forward operator and adjoint assimilation code Validating model clouds and physical parameterisations Choices of observation error, QC and bias correction

34 ECMWF NAEDEX 2012 – ECMWF Status Report – Stephen Engilsh Summary Data volumes / instruments continue to increase Automated alert system now fully operational Early CrIS and ATMS results are encouraging Loss of ENVISAT was a major event, especially for ocean and ozone analysis Principal component assimilation has been demonstrated for cloud-free scenes FY3 characterisation led to very valuable re- analysis of errors in MSU and AMSU-A data record EDA techniques used to try to estimate sensitivity of system to number of GPSRO observations
