Following a reset of the DPR to Standby Mode that occurred on April 22, 2020, the DPR Ka radar data acquisition has been restored. PPS is releasing the DPR and downstream data for distribution from April 22, 2020 - April 30, 2020. There are continuing short data outages for the radar that are being investigated and corrective measures are scheduled to be applied on May 14, 2020. PPS will be releasing May 2020 data in stages with an expected return to normal data availability soon after the corrective measures are applied. For Level-1 and Level-2 products, users should check the dataQuality

The IMERG Algorithm Development Team is currently developing the next version of IMERG, V07. To help us prioritize our efforts, we have created a survey for users to identify aspects of IMERG that they consider important. Your responses will help us decide how we should focus our development effort for V07 and beyond. We deeply appreciate your responses. The survey is located at https://forms.gle/hgSMBXx7a2ScWpRSA This survey should take no more than 5 to 10 minutes. It is open through Monday, June 15.

At 11:00 UTC on 18 June 2020, FTP access to jsimpson will no longer be possible. The stoppage was originally scheduled for 1 June 2020 but due to the impacts of the CoVid19 pandemic, the end of FTP was delayed. Effective 11:00 UTC 18 June 2020, both jsimpson.pps.eosdis.nasa.gov and jsimpsonftps.eosdis.nasa.gov will provide FTPS access to GPM NRT data. FTPS will be the main, 24hr/7day retrieval protocol for getting GPM NRT data from PPS. Remember PPS implements explicit FTPS, FTPS retrieval will require your system administrators to open ports 64000-65000. You can find examples of using curl and wget for FTPS access to data on jsimpson in /NRTPUB/documentation/FTP-FTPS-Transition.pdf

As previously announced, with the recent release of the long-record V06B IMERG Early, Late, and Final products in late summer of 2019, processing of the TMPA-RT and TMPA products is ending, with December 2019 being the final month of data. This means that TMPA-RT products have already ceased production and the TMPA products will end with December 2019 (expected by March 2020). Thanks go to the PPS team, who managed to keep some really old computer hardware alive long enough to meet this goal! These legacy products will continue to be hosted at PPS and GES DISC to allow users sufficient time to

PPS is announcing the availability of the new NOAA20_ATMS products which will be available starting today, Tuesday September 04, 2018 The NOAA20_ATMS data range starts with November 29, 2017 and will be processed to the current date. November/December 2017 products will be available this afternoon. The corresponding PPS TKIO to be used with this data is tkio 3.80.26: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.80.26/ PPS is currently processing the following NOAA20_ATMS products (below). The entire data set will be available over the next couple of weeks. This consists of

PPS is releasing version 3.90.0 build of the PPS TKIO toolkit to the public. This version is currently being used for PPS GPM data production. The tar file directory along with the release notes can be found at: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.90.0/ We have also attached these corresponding release notes for your convenience. If you have any questions, comments or concerns, please contact the PPS Helpdesk at: helpdesk@mail.pps.eosdis.nasa.gov

The Precipitation Processing System (PPS) will begin processing and reprocessing GPM Level 2 - Level 3 DPR and Combined data as version V06A. The switch to V06A for these products will begin with October 01, 2018 GPM data. This data will be available to the public after October 04, 2018 at the earliest once they have been reviewed and approved by the Science Team. The following data products will be processed/reprocessed as V06A: 2AKa 2AKu 2ADPR 3DPRD 3DPR_ASC 3DPR_DES 3DPR 2BCMB 3CMB_DAY 3CMB 2HSLH 3GSLH 3HSLH_DAY 3HSLH These GPM data products will be made available through the PPS "arthurhou

The Precipitation Processing System (PPS) is scheduled to begin TRMM L2-L3 Combined GPM V06A data reprocessing on Wednesday October 31, 2018. These TRMM/GPM data products will be made available through the PPS "arthurhou" ftp archive: ftp://arthurhou.pps.eosdis.nasa.gov/ and STORM (PPS's Online Data Ordering Interface): https://storm.pps.eosdis.nasa.gov after these products are produced and archived. NASA requires that all science data users register in order to access these products. If you haven't registered, please visit the PPS registration portal at: https://registration.pps.eosdis.nasa

Effective on the date and time above, all the NRY GPROF data product verson numbers were changed by increasing the letter of the data product version. This letter change means that data products were changed but no backward processing is undertaken. Only the products forward of the date/time have been altered. So, for GMI GPROF the vesion changed from V05A to V05B. Other instrument GPROF retrievals had a similar change but appropriate to their starting data product version. The algorithm itself did not change but some of the database profiles did. The algorithm team provided the following

Beginning on Monday February 04, 2019, the Level 2 and Level 3 GPM GPROF products will be produced with an updated monthly emissivity class file (see developers comments below). PPS will increment the product version for all Level 2 and Level 3 GPROF products starting with the first full orbit on data date February 1, 2019. The current version of these products will cease with data date Jan 31, 2019 and will remain unchanged. The new production version numbers/ designations will be incremented as shown in the table below. Data Source Product Version F16_SSMIS V05B F17_SSMIS V05B F18_SSMIS V05B
