GMI Spins Up, goes to Science Mode
The Global Precipitation Measurement mission Core Observatory is performing normally. Today, the GPM Microwave Imager (GMI) instrument started to spin at its normal rate and collect science data on rain and snowfall.
The GMI instrument is a multi-channel microwave radiometer that uses 13 channels to measure the intensity of the microwave energy emitted from Earth's surface and atmosphere. GMI will detect total precipitation within all layers of clouds, including snow and ice, and rain from drizzles to downpours.
