Abstract

Contracted by the European Space Agency (ESA), the European Centre for Medium-Range Weather Forecasts (ECMWF) is involved in global monitoring and data assimilation of the Soil Moisture and Ocean Salinity (SMOS) mission data. To this end the Community Microwave Emission Model (CMEM) has been developed by ECMWF as the forward operator for low frequency passive microwave brightness temperatures (from 1GHz to 20 GHz) of the surface. CMEM is a new highly modular software package providing input/output interfaces for the Numerical Weather Prediction Community. CMEM's physics is based on the parameterizations used in the L-Band Microwave Emission of the Biosphere and Land Surface Microwave Emission Model. CMEM modularity allows considering different parameterizations of the soil dielectric constant as well as different soil approaches (either coherent of incoherent) and different effective temperature, roughness, vegetation and atmospheric contribution opacity models. This report is Part 1 of the first Milestone Technical Note / Progress Report of the ESA Request for Quotation RfQ 3-11640/06/I-LG. It provides a scientific and technical documentation of CMEM.
