NOAA Network Restored

The NOAA network is gradually being restored. MHS data appears to have started flowing around 02:00 UTC on 23 October 2014, but as of 08:00 UTC on 23 October 2014 the Meteosat geo-IR data was still missing. As a result, users should see reduced areas of "missing" and higher-quality estimates in general starting with the 03:00 UTC 23 October 2014 3B42RT.

3B4xRT Reduced Volume of Data

Starting about 22:00 UTC on 20 October 2014 PPS started having issues with missing input data files originating at NOAA. Informally we have been told that there is a major network issue, but have no insight on its nature or likely duration. Until this is resolved, the input data for the 3B4xRT suite of products will suffer greatly reduced volume. Currently, we are not receiving sounder data, and the IR fields only have GOES-E and -W.

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.

Explanation of Data Products

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...
