Precipitation Processing System (PPS) PPS provides 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, PPS 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 PPS and then processed by the first tier of science algorithms to produce calibrated, swath-level instrument data.

Precipitation data sets, referred to as "products", are available at a variety of levels which denote the amount of processing that data has been through. These range from the raw instrument data to precipitation model outputs which are mathematically derived using the raw data as an input. Below are the definitions for each level: Level 0 Raw instrument data Level 1A Reconstructed, unprocessed instrument data at full resolution, time referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and georeferencing parameters (i.e., platform...

Coming Soon! This page will allow you to log into the PMM Science Team Portal to collaborate with your fellow scientists. Some of the features we are planning include: The ability to create personal profiles and view the profiles of your teammates. A wiki / forum for communication and sharing of ideas. A tool to schedule meetings with your fellow scientists. A tool for sharing documents and files. Check back here for updates on the status of this tool.
