TDRS 171 in safehold: Increased latency on GPM near-realtime products

One of the TDRS satellites which GPM uses for downloading data is currently in safehold. This means that all downloads scheduled for that satellite wiil obviously not be able to be met. This will increase the latency of all GPM NRT products. One missed pass has already occurred and led to increased latency. Several others will occur during the night and into tomorrow.

V04A IMERG Early GIS friendly products now available

PPS has completed the production of the GIS-friendly TIF/TFW products created from the IMERG Early dataset. These products include running accumulations at 3hr and 1day. The Early TIF/TFW GIS-friendly products have been created back to the beginning of the mission: March 2014. They can be found on jsimpson server in the directories: /NRTPUB/imerg/gis/early/YYYY/MM Documentation for the TIF/TFW products is contained in the document README.GIS.pdf in /NRTPUB/imerg/gis.

June 15 GPM NRT outage: 14:15 UTC to 15:15 UTC

Date of Event: 15 June 2017 Start Time of Event: 13:15 UTC Schedule stop time: 14:15 UTC GSFC networking personnel will be replacing network equipment that will directly impact GPM MOC, both its connection to PPS AND, more significantly, its connection to White Sands (WSC) which is the download location for GPM data. Since this replacement will provided needed increase in network throughput capacity, the update is required. During the outage, PPS SDPS (tnitta) will receive NO GPM DATA. While only an hour is currently planned for the outage as with any network modifications, changes might take

Status of IMERG v04 Products

In an effort to keep users informed, below is the current status of the IMERG V04 products. Summary 1. As of 02:20 UTC on 9 May 2017, IMERG Early and Late are running in V04 with backward compatibility adjustments to V05 inputs. 2. From that point to about 11:30 UTC on 12 May 2017, there are long, thin streaks of artifacts in IMERG Early and Late due to GPROF-ATMS. 3. From that point to about 15:00 UTC on 30 May 2017, there are unrealistically large areas of light rain in moist tropical ocean areas in IMERG Early and Late due to GPROF-ATMS and GPROF-MHS. Thereafter, the content of microwave

PPS Releases GPM V05 DPR L1-L3 and Combined L2- L3 Data

PPS is releasing GPM V05 DPR L1-L3 and Combined L2 and L3 V05 data products today, Wednesday May 17, 2017. This V05 data will be available beginning with May 01, 2017 data and forward. The DPR Level 3 monthly products will be released when validated. Reprocessed V05 DPR and Combined data for March 2014 through April 2017 will take several weeks to complete. This data will appear in PPS's arthurhou archive as we reprocess (6 to 8 weeks - estimated completion time). Registered users can obtain data from: ftp://arthurhou.pps.eosdis.nasa.gov/ and can order this through STORM: https://storm.pps

V04 Reprocessed Early and Late IMERG products

The GPM project has reprocessed all the original NRT IMERG data both EARLY and LATE to product version V04A. In addition, this reprocessing brought the IMERG dataset back to the beginning of the GPM mission in March 2014. The original NRT IMERG started its processing in March of 2015. Currently only the HDF5 products have been reprocessed to V04A. The TIFF/TFW versions will also be reprocessed but this will take a while longer. The V04 products are located in the directories early/YYYYMM and late/YYYYMM respectively. A subdirectory V03 has been created within those directories and the V03 data

Start of V05A NRT Swath Products

Effective approximately 04:00 UTC, 9 May 2017 the near-realtime swath products (GMI, partner constellation, radar and combined) will be upgraded from V04 to V05. During the conversion the latency of near-realtime will be affected as all the new code and support files need to be modified to carry out this upgrade. We hope this will take no more than 2 hours but can not guarantee it might not be longer. We will start with the upgrade of radar products, followed as quickly as possible by GMI and then the partner constellation products. We are starting with the radar as this requires close

GPM V05 Data Announcement and IMERG

The Precipitation Processing System has begun the transition to GPM Version 5 products. The satellite observations made in April 2017 will be the last observations to be included in Version 4 of the GPM data products, with one exception. Starting with observations made in May 2017, PPS will generate Version 5 GPM data products, again with one exception. The exception in both cases is that the PPS Realtime system will continue to generate the Version 4 Early and Late IMERG data products. Version 4 data products have been removed from the STORM data ordering system ( https://storm.pps.eosdis

Change in IMERG early 2/5/2017-3/12/2017

During the initial setup up for V04 IMERG, an error was made in the configuration for running the EARLY version of IMERG. This affected the V04A early data from Feb 5 - March 12, 2017. This error caused the early and the late products to be identical. Given that the LATE product is the more accurate product this might not be an issue for many users. However, users who need a consistent approach in the early data will need to download IMERG early Feb 5-March 12, 2017 again. On April 12, 2017 at about 16:55 UTC Feb 5-Feb 28, 2017 files have been rerun and are available from their usual location

PPS Releases GPM IMERG V04 Final Data Products

PPS is announcing the release of GPM IMERG V04 Final products today, Wednesday March 22, 2017. Version 04 IMERG data is available on PPS's arthurhou ftp archive for the dates of March 2014 - July 2015. Processing will continue over the next several weeks until the data has been made available up to the present. This data can be found at: ftp://arthurhou.pps.eosdis.nasa.gov/gpmallversions/V04 Individual data orders, subsets or subscription orders can also be set up through PPS's STORM: https://storm.pps.eosdis.nasa.gov/storm/ Release notes and ATBD documentation for IMERG V04 can be found at
