Assessing the impact of spatial filters applied during resampling on the Metop ASCAT SZF product

The backscatter data collected with the Advanced SCATterometer (ASCAT) carried on board of the Meteorological Operational (MetOp) series of satellites represents a fundamental parameter for many important applications such as: ocean winds assimilation, weather forecasting, sea ice monitoring, snow accumulation and soil moisture retrieval. The first level of geolocated measurements is represented by the full-resolution backscatter product (SZF) provided by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) which is further resampled to obtain spatially averaged products. The resampling process is a crucial step, since the type and size of the spatial filter strongly influence the resulting product, imposing restrictions on its further use. The aim of this thesis is to describe and assess the effects of different spatial filters applied during resampling of backscatter over land. The ASCAT SZF product will be spatially averaged using a Boxcar window and a Hamming window with various sizes. Several experiments will be performed in order to compare the effects of the different filters and to estimate the impact on later products.
