TRMM Combined Precipitation Radar and Microwave Imager Rainfall Profile L2 1.5 hours V7 (TRMM_2B31)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/rjq34l8s02r1
This is the last version of the TRMM-formatted, in HDF4 format, Combined (Radar-Radiometer) product, which is in a state of permanent preservation.
Description
New version that is consistently processed with Global precipitation Measurement (GPM) algorithms, and in a consistent with GPM HDF5 format, is available under short name 'GPM_2BCMB_TRMM'. The dataset TRMM_2B31 combines data from the TMI and PR to produce the best rain estimate for TRMM.
This combined rainfall product is derived from vertical hydrometeor profiles using data from the PR radar and TMI. It also includes computed correlation-corrected, mass-weighted, mean drop diameter and its standard deviation, and latent heating data. Pre-Boost (before 7 August 2001): Temporal Resolution: 91.5 min/orbit ~ 16 orbits/day; Swath Width: 215 km; Horizontal Resolution: 4.3 km Post-Boost (after 24 August 2001): Temporal Resolution: 92.5 min/orbit ~ 16 orbits/day; Swath Width: 247 km; Horizontal Resolution: 5.0 km
