L-band SMOS brightness temperature measurements have been monitored for a long time at ECMWF using the Community Microwave Emission Modelling Platform (CMEM) forward model. CMEM is a well-established model to simulate L-band measurement over land. Over inland water bodies, coastal areas and open ocean, instead, a simplified emissivity model is used that does not account for the wind and foam dependent emissivity changes. L-band measurements over the ocean are known to be sensitive to high winds and could provide Numerical Weather Prediction (NWP) systems with wind information not given by other higher frequency passive measurements or active instruments.
