Abstract

Backscatter data from the SeaWinds scatterometer on the QuikSCAT satellite are used to delineate floods over the Asian, continent. SeaWinds acquires Ku-band (13.4 GHz) data at the vertical polarization over a very large swath of 1800 km, and at the horizontal polarization over a 1400-km swath. The authors present the flood areas together with topography on land and wind field on ocean. Results show extensive floods in China, India, Bangladesh, and other Asian countries. Timely flood mapping can provide crucial information for flood relief efforts
