When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global... (View More) Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities. (View Less)
