PPS will start the TRMM version 8 level 1 processing on Monday October 2, 2017. All products will be produced as GPM version V05. All the TRMM products are in HDF5 format with internal compression (same as the current GPM products), and will be produced using the PPS Toolkit (TKIO) version 3.80.29. The TRMM product names will be changing using the GPM naming conventions. The GPM naming convention document can be found at: https://pps.gsfc.nasa.gov/Documents/FileNamingConventionForPrecipitatio…. TRMM version 8 level 1 products have new identifiers, 1ATMI, 1BTMI, 1AVIRS...

On September 26 at about 14:45 UTC the GPM radar was commanded to undertake an experimental Ka scanning approach. As the radar is not in normal observational mode no normal observational data is being generated from either the Ku or the Ka radar. This situation will continue until approximately 14:40 UTC on 29 September 2017 when the radar will be commanded back to its observational scanning approach.

For V05 we produced a daily gridded text product for precipitation data from the core satellite and from the partner constellation imagers. We also produced a monthly rollup of these gridded text products. They were all designated with the product version V05A. If you downloaded these products, we regret to inform you that we found an error in the calculation of convection rate and frozen rate. While the mean precipitation rate values were correct in V05A, convective and frozen rates were erroneous. We have made the necessary changes to the code that produces these products. After extensive...
