GMI Instrument Is The Calibration Standard For The Entire GPM Constellation To Improve Understanding Of Precipitation Patterns Around The World
The Global Precipitation Measurement (GPM) Microwave Imager (GMI), designed and built by Ball Aerospace for NASA's Goddard Space Flight Center, is entering its fourth year of service. Designed as a 3-year mission, GMI has performed successful operations on orbit while exceeding its performance requirements. The GPM spacecraft that hosts the GMI instrument is a joint effort between NASA and the Japan Aerospace Exploration Agency (JAXA) to provide frequent, near-global precipitation information critical for improving weather forecasting and protecting lives and property.
