GPM PR and TMI on TRMM (Combined Precipitation) L3 1 month 0.25x0.25 degree V06 (GPM_3CMB_TRMM) at GES DISC
This is the new (GPM-formated) TRMM product. It replaces the old TRMM_3B31 This is the GPM-like formatted TRMM Combined Precipitation (TRMM Ku radar and microwave radiometer/imager), first released with the "V8" TRMM reprocessing. Gombined Radar-Radiometer Algorithm performs two basic functions: First, it provides, in principle, the most accurate, high resolution estimates of surface rainfall rate and precipitation vertical distributions that can be achieved from a spaceborne platform, and it is therefore valuable for applications where information regarding instantaneous storm structure are vital. Second, a global, representative collection of combined algorithm estimates will yield a single common reference dataset that can be used to “cross-calibrate” rain rate estimates from all of the passive microwave radiometers in the TRMM and GPM constellations. The cross-calibration of radiometer estimates is crucial for developing a consistent, high time-resolution precipitation record for climate science and prediction model validation applications.

Collection Information
Data Identification
-
Processing Level
3
- Quality The results presented in the Level 3 product are simple conditioned statistics of the Level 2 retrievals. Any errors/limitations are inherent to the Level 2 retrieval issues already presented. Issues with sampling must be considered when using these data. For the daily products, the number of measurements in each 0.25-degree box is very limited. While this is a convenient resolution that can be used to create larger grids, the values at the 0.25-degree resolution should be used with caution. The standard deviation is not computed at the daily level for this very reason.
