Basic information about the Tropical Rainfall Measuring Mission (TRMM) satellite, including overview of satellite and sensors, is available from here.@@
On MOVIE, the electric wave shown in yellow is emitted from TRMM Microwave Imager (TMI). The electric wave shown in pink is emitted from Visible Infrared Scanner (VIRS). The green and shown electric wave is emitted from Precipitation Radar (PR). In TRMM, data with more high accuracy can be obtained by performing observation by these equipments simultaneously.
