TRMM (Tropical Rainfall Measuring Mission) - TRMM's mission is to measure the rainfall all around the tropics where most of the world's rain falls. These measurements will include the large ocean areas where very little is known about the rain. By studying these measurements, scientists will be able to know what the normal rainfall is and maybe what the normal changes are from one year to the next.

TRMM Science Data and Information System (TSDIS) - The real-time processing and post-processing of the TRMM science data is performed by the TRMM Science Data and Information System (TSDIS). Working with
the TRMM principal investigators and science algorithm developers, TSDIS maintains the operational science data processing system and ensures the timely
processing of all TRMM science instrument data. During routine operations, raw instrument data is received in near real-time by TSDIS and then processed by the
first tier of science algorithms to produce calibrated, swath-level instrument data. Using this calibrated, swath-level instrument data, the second tier of algorithms are
used to compute geophysical parameters, such as precipitation rate, also at the swath-level resolution. At the final stage of TSDIS processings, the third tier
algorithms produce gridded geophysical parameters from the first- and second-tier instrument data. All TRMM products are archived and distributed by the Goddard
Distributed Active Archive Center (DAAC). For further information concerning TSDIS operations go to ths TSDIS homepage.
