Atmospheric reanalysis at ECMWF

Reanalysis can be used to remove biases from observations Variational bias correction of satellite radiances in ERA-Interim Dee and Uppala 2009 (QJRMS, in press) Global mean bias corrections for MSU channel 2 (lower troposphere) Equator crossing times for NOAA Polar Orbiting satellites Drift in polar orbit causes changes to the total heat budget of the satellite This affects instrument self-calibration

MSU instrument bias due to warm-target fluctuations Variational bias estimates for NOAA-14 Actual warm-target temperatures on board NOAA-14 (Grody et al. 2004) MSU instrument errors are identified based on all information available to the reanalysis
