Application of merged satellite and radar data for flood risk reduction in urban area

Abstract:

The natural disaster from heavy rainfall and Typhoon are increased damage of property and human life in urban area with the impact of climate change. Therefore the accurate observation and short-term forecast of heavy rainfall by multi-sensor is very important for reduce damage from severe storms and Typhoon. This study develops flash warning systems based on Communication, Ocean and Meteorological Satellite(COMS) geostationary satellite data and ground radar. The proposed system has been developed blending rainfall forecasting highly time and space resolution successive the brightness temperatures(TBs) from IR image of COMS with rain/no-rain classification of ground s-band radar. This system was evaluated to case study of the sudden rainstorms by the Automated Weather System(AWS) around Korea peninsular on summer season.
