Improving GSMaP Precipitation Estimates Using a Modified Kalman Filter With Lightning Flash Rate (opens in new tab)

Precipitation drives various Earth’s processes and is linked to hazards such as flash floods and drought, making timely and accurate monitoring of precipitation crucial for disaster mitigation. The Global Satellite Mapping of Precipitation (GSMaP) provides high-resolution rainfall data by combining microwave radiometer (MWR) and infrared (IR) retrievals. Since MWR retrievals are limited and only available every 3 h, GSMaP’s near-real-time (NRT) product propagates MWR measurements forward in t...
