Being able to provide reliable precipitation information is crucial for many hydrologic applications, such as flood and drought monitoring and water resources management. Recent advancement of satellite-based retrieval techniques has made it possible for monitoring precipitation at over the regions where in-situ observations are limited. In this presentation, the development of operational satellite-based global precipitation monitoring system at UC Irvine will be introduced. The developed system integrates both sensors and sampling capability from Low Earth Orbit (LEO) and geosynchronous (GEO) satellites for making effective precipitation estimation. Evaluation of the satellite-based estimation will be demonstrated and application of satellite-based precipitation measurement in hydrologic modeling of soil moisture and steamflow will be discussed.
