Abstract
The combination of passive and active microwave satellite data products should give new and improved insight into the structure and development of sub-synoptic scale circulation systems in the Earth's atmosphere, as e.g. polar lows, comma clouds and tropical cyclones. The present study focuses on wind speeds in severe storm systems derived from microwave radiometers and altimeters in comparison with related products from the Envisat mission. Especially, the influence of precipitation on the accuracy of wind speed estimates is analysed through this combination technique. Preliminary results suggest only minor errors through undetected signal contamination by precipitation.
