Data News

Starting with the first orbit of 9 October 2017, the MHS data from NOAA-19 began displaying substantial artifacts. After the orbit crossing 00 UTC 10 October, the NOAA-19 data have been embargoed from Early and Late IMERG, although it took until 03 UTC for all artifacts to age off the morphing. At this point, Early and Late IMERG appear nominal, except they lack the sampling that NOAA-19 provides.

With the completion of the TRMM version 8 level 1 processing, PPS will start to process the TRMM era GPM constellation level 1 data on Friday October 6, 2017. Similar to the TRMM version 8 level 1 product, all level 1 constellation products will be produced as GPM version V05, all products are in HDF5 format, all product names will use the GPM naming convention and the produced data will appear both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ PPS will reprocess the entire TRMM era constellation data. All users are encouraged to

Starting with data date October 01, 2017, the Level 2-Level 3 GPROF data for METOPA, METOPB, NOAA18, NOAA19 (MHS) and NPP ATMS partner products will be running new code and produced as product version V05C. These code changes are relatively minor and primarily affect the outer edges of the swath. Processing of the V05C data will start tomorrow on Wednesday October 04, 2017. Notable changes include : ------------------------------------------- The V05C GPROF of the Cross-track sensors allows for more usable pixels on the outside of the MHS and ATMS scans as compared to the previous version. For

PPS received new GPM Ka L1B products (2017-09-29) for orbit 20378 from JAXA and reprocessed the affected data.

PPS is releasing version 3.80.29 build of the PPS TKIO toolkit for GPM Version 5 products and TRMM Version 8 data products This can be found at: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.80.29/ The direct link to the tar file can be accessed here: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.80.29/tkio-… The most recent changes are in metadata: 3GSLHT cu3cw 3HSLHT cu3cw Other changes are noted in the release notes documents in the FTP directory. Please contact us for any questions.

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
