Abstract

This study develops a method for precipitation retrieval algorithm and a rain/no rain cloud classification system using Korea geostationary satellite images as well as GPM (Global Precipitation Misssion), DPR (Dual Precitation Radar), and GMI (GPM Microwave Imager) sensors. This method can be applied to rainfall observations in the Korea region. Co-locaed GPM CMB Level 2 precipitation with rain flags, precipitation type flags, land/ocean flags, convective/stratiform flags, cloud top height flags, and COMS geostationary satellite 5 channels are employed to develop real-time flood forecasting and monitoring systems for self-governing bodies. Shortwave infrared, water vapor, and infrared 1 channels are used to classify rainfall clouds from clear sky conditions. The new algorithm was used to perform validation when compared with old algorithm based on Tropical Rainfall Measuring Mission (TRMM) satellite for Busan city flood case at August 25,2014.
