Abstract
The Tropical Rainfall Measuring Mission (TRMM) will have completed nine years in orbit in November 2006. This successful research mission, a joint U.S./Japan effort, has become a key element in the routine monitoring of global precipitation. The package of rain measuring instrumentation, including the first meteorological radar in space, continues to function perfectly, and with the increase in orbital altitude (from 350 km to 400 km) in August 2001 and the mission extension approval in 2005, the satellite has sufficient station-keeping fuel to potentially last until 2012, or perhaps longer. The status of TRMM algorithms and products will be summarized, including the impact of the altitude boost in 2001, and the plans for the upcoming Version 7 of the products will be outlined. The role of TRMM as part of the constellation of rain-measuring satellites preceding GPM will be discussed, as well as its role in climate analysis using its unique radar/radiometer combination.
