The TRMM Microwave Imager (TMI) Gridded Orbital rainfall data, a special product derived from the TRMM standard product, TMI rain profile (2A-12), and mapped to a 0.5 degree x 0.5 degree latitude/longitude grid. The spatial coverage is defined by a 760 km swath bounded by the latitudes 38 degree N and 38 degree S for a single satellite orbit. The parameters included in this data set are the mean, standard deviation, and number of samples for the conditional surface rain rate; and the cloud water at 14 vertical levels in the rain column. The document also provides the information necessary to readily access and interpret the parameters stored in the files.
Information and data access for all of the Goddard DAAC's hydrology data holdings, including TRMM data from the TMI, Precipitation Radar (PR) and Visible and Infrared Scanner (VIRS) instruments, the Ground Validation (GV) radar data, and ancillary and correlative data products.
Horizontal Resolution Range:
50 km - < 100 km or approximately .5 degree - < 1 degree
Vertical Resolution Range:

16 orbits per day
Quality flags have been included with the data to give users a sense of the confidence placed on the individual retrievals. Data will be reprocessed as characteristics of the sensor become better understood and enhancements are made to the science algorithms.
