What is the global projection used for TRMM and GPM Level-3 data?
The projection used is, geographically, the Equirectangular projection, and the datum is WGS84.
When import the data into GIS software (e.g., ArcGIS, Erdas/Imagine, ENVI), select the global WGS84 "Geograhic" coordinate system as spatial reference/projection info.
