TRMM_3B31_7

TRMM TMI/PR Combined Precipitation L3 1 month 0.5 degree x 0.5 degree V7 (TRMM_3B31) at GES DISC

Version 7 eng
  • Abstract
    This is a combined rainfall product. 3B31 uses the high quality retrievals done for the narrow swath in 2B31 to calibrate the wide swath retrievals generated in 2A12. For each 0.5 degree box and each vertical layer, an adjustment ratio is calculated for the swath overlap region for one month. Only TMI pixels with 2A12 pixelStatus equal to zero are included in monthly averages, which effectively removes sea ice.

    Quality
    The current version of 3B31 only checks various quality flags in the 2A12, but not the 2B31. The recent version of 2B31 has provided an uncertainty index. The quality check of 2B31 will be added in the next version to remove any input data with poor quality. Pixels for which the 2A12 is either zero, or unreliable, currently do not allow the user to reconstruct the 2B31 original solution.
