The National Aeronautics and Space Administration (NASA), Science Mission Directorate, Earth Science Division has selected new projects from the 2018 Precipitation Measurement Missions (PMM) Science Team focus area solicitation. PMM projects focus on investigations related to satellite observations of precipitation using measurements from, but not limited to, the Global Precipitation Measurement (GPM) Core Observatory, GPM mission constellation partner spacecraft, and the Tropical Rainfall Measuring Mission (TRMM). Specifically the PMM program supports three types of investigations: (1) The

This animation shows NASA IMERG rain rates (blue shading) and accumulations (green shading) near Kyushu island, in the southwest of Japan from June 29 - July 5, 2020. Devastating floods and landslides swept through parts of Kyushu on July 4, 2020, resulting in over 40 deaths and orders for hundreds of thousands of people to evacuate their homes according to media reports. Download video (right-click -> Save As) The rains that triggered the flooding occurred in the context of the Meiyu-Baiu rainy season, which arrives in east Asia every year from June to mid-July. “Meiyu” and “Baiu” are the

To reduce risks from natural disasters and build climate resilience, decision makers are using NASA Earth observations to develop index-based insurance products and protect low-income customers in Central America, especially in the region known as the Dry Corridor.
