The purpose of this software is to implement real-time radar monitoring technique in meteorological service through industry-academia cooperation. The design transforms professional weather webpage into APP software, which is available for mobile devices, it also provides notification service by using GPS positioning system. This is an experimental product which integrates radar observational data in Taiwan with the latest observation data from FORMOSAT-7. By using data assimilation method and radar reflectivity extrapolation method, it develops real-time early warning technique and provides probability of precipitation information in future 1 hour.
