The European Centre for Medium-Range Weather Forecasts (ECMWF) currently prepares the assimilation of soil moisture data derived from advanced scatterometer (ASCAT) measurements.
ASCAT is part of the METOP satellite payload launched in November 2006 and will assure the operational provision of soil moisture information until at least 2020. In several studies it has been shown that soil moisture derived from scatterometers contain skilful information. The objective of this paper is to evaluate the potential of ASCAT soil moisture data for numerical weather prediction. For this purpose scatterometer derived soil moisture will be compared to ERA-40 reanalysed soil moisture and a simple nudging experiment using ECMWF´s Integrated Forecast System (IFS) will be carried out. The results of the assimilation experiment are compared to field observations from the Oklahoma Mesonet.
