Tropical Rainfall Measuring Mission To Be Decommissioned

NASA plans to decommission the Tropical Rainfall Measuring Mission (TRMM) later this year. TRMM was originally launched as a three-year demonstration mission in 1997 and will be replaced later this decade by the Global Precipitation Measurement mission (GPM) through a partnership with the Japanese Aerospace Exploration Agency (JAXA). TRMM measures precipitation distribution over land or sea and aids in predicting dangerous weather, as well as in understanding Earth's hydrological cycle and climate.
