Abstract
The unified retrieval approach is applied to Defense Meteorological Satellite Program (DMSP) 5D-2 microwave sensor data (i.e. SSM/I, SSM/T, SSM/T-2) combined with that from visible and infrared cloud imager data in a physically based approach to optimally infer the state of the atmosphere/ocean background. Surface emissivity and cloud liquid water are treated explicitly and are retrievables. The system is compatible with numerical weather prediction data assimilation and can utilize forecast first guesses in the fully interactive mode. We present validated retrievals of atmospheric temperature profiles, water vapor profiles, cloud liquid water, surface temperature and surface emissivity obtained from DMSP sensor data from the F-11 spacecraft for which limited radiosonde collocations are available. We note the utility of the retrieval system, specifically the residuals, to diagnose: phenomenon omitted from the forward problem such as cirrus cloud, spatial inhomogeneities of retrieved quantities such as water vapor and cloud, and data inconsistencies such as biases between channels and instruments. The retrieval system developed is equally applicable to other meteorological sensor payload combinations such as the OLS-SSM/IS, AMSU/MHS, and AVHRR/HIRS.
