Abstract Contracted by the European Space Agency (ESA), the European Centre for Medium-RangeWeather Forecasts (ECMWF) is involved in global monitoring and data assimilation of the Soil Moisture and Ocean Salinity (SMOS) mission data. For the first time, a new innovative remote sensing technique based on radiometric aperture synthesis is used in SMOS to observe soil moisture over continental surfaces and ocean salinity over oceans. Monitoring SMOS data (i.e. the comparison between the observed value and the model equivalent of that observation) is therefore of special interest and a requirement prior to assimilation experiments. This report is the first part of a series of Monitoring Reports of the ESA Request for Quotation RfQ 3-11640/06/I-LG. The objective is to report on the monitoring activities of SMOS data over land and sea on a long term basis, exploiting also the multi-angular and multi-polarised aspect of the SMOS observations. Some of the first results obtained are shown in this report. Some case studies have also demonstrated the ability of SMOS data to observe soil moisture in all weather conditions.
