Abstract
A new, fast radiative transfer model including scattering has been developed for the purpose of microwave radiance assimilation in cloudy and precipitating areas. The model uses a technique called successive order of interaction (SOI) which is based on a blending of the doubling and the successive order of scattering techniques. An adjoint and tangent linear version of the model are also available. Within this paper we present first applications of the SOI model. We compare brightness temperatures simulated from NCEP's Global Forecasting System (GFS) using a non-scattering version of the SOI model with global satellite data obtained by the Advanced Scanning Microwave Radiometer (AMSR-E) onboard NASA's Aqua spacecraft. Additionally, we show first sensitivity studies using the adjoint model for cases that include scattering by liquid and frozen precipitation.
