Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07.The same algorithm has been applied to TRMM observations (December 1997 - April 2015) and these data can be found under product name GPM_2BCMB_TRMM.This is a precipitation product created from the combination of the Global Precipitation Measurement (GPM) Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments.The 2BCMB product uses data from the Dual-Frequency Precipitation Radar and GMI, determining the precipitation structure that best fits the combined data from these instruments. It is the Level 2 DPR and GMI Combined precipitation product that contains the data acquired by the GPM instruments in one orbit, or granule. It is written as a two-swath structure. The first swath, NS (normal scan), contains 49 rays per scan that match the KuPR rays. It is calculated from the KuPR and GMI data. The second swath, MS (matched scan), contains 25 rays per scan that match the 25 KaPR rays. It is calculated from the KuPR, KaPR, and GMI data.
