Data

The new V07B IMERG Late and Early Run products commenced processing around 1300 UTC on 6 June 2024, starting with data for 0000 UTC on 1 June 2024. It will take a number of hours for the days before 6 June to be processed, after which users should see the normal latencies of 4 and 12 hours for Early and Late, respectively. Note that the polar regions are initially largely set to "missing" in the Early Run because input data for times before 1 June that would normally be used for forward morphing are not provided as part of the startup.

Due to unforeseen issues with the recent GPM near real-time system updates, IMERG V07B Early and Late Run production has been delayed. Currently the PPS plans for IMERG V07B Early and Late Run data to begin production on June 6, 2024. GPM L1 and L2 data has already resumed production, and can be accessed on the the jsimpson and jsimpsonhttps servers.

Recent hardware and operating system changes in the PPS near real-time system have presented challenges that are preventing the production of the new V07B Early and Late Runs at present. One feed for a major input data source is in the process of being enabled, after which the Early and Late should be ready to begin production. The most likely scenario is that this start will happen tomorrow, June 5, at which point the record will be started from June 1.

As announced earlier in the month, the PPS are updating the GPM near-realtime (NRT) servers on Monday, June 3. The IMERG product will also be updated to V07B at this time. Details: The update will start at approximately 10:00 UTC 3 June 2024 No NRT products will be produced for about 4 hours during the system update. This also means no L1 GMI, radar, combined, partner products, or L2 products will be produced during this time. Following successful system updates, PPS will the start L1 and L2 data production. The PPS will install the IMERG V07B algorithms. The IMERG NRT V07B products, when

The PPS has moved the date of the GPM Near-realtime (NRT) computing system updates to take place on Monday, June 3, 2024. At this time, IMERG will also be updated to V07. June 1 and 2 IMERG data will be included in the “initial processing”, so that the entire month will be available at V07 without having to wait for the Final to be processed at the usual 3.5-month latency. PPS has already made available on jsimpson.pps.eosdis.nasa.gov and jsimpsonhttps.pps.eosdis.nasa.gov IMERG V07B Early Run retro-processed data. The V07B data is in /NRTPUB/imerg/early/ subdirectories: 200006-200012 200101

On June 1, 2024, the Precipitation Processing System (PPS) will be performing updates and maintenance on the GPM near real-time (NRT) servers. As a result, GPM NRT data will not be produced during this time and it's expected that the GPM NRT servers will be inaccessible for several hours. In event of anomalies during the update process, the servers may be down for a few days. In addition, the following updates are planned for IMERG V07: On June 1, 2024, hour 00, IMERG V07 Early and Late will begin production at the PPS (Initial Processing [IP]). Any June 1 data generated before the V07 update

The post-boost GPM radar and radiometer algorithms are now successfully running at the PPS, and data products using the new algorithms are available for download as of March 7, 2024. Please see this post for more information: https://gpm.nasa.gov/data/news/final-post-boost-radar-algorithms-v07-be…

This morning at about 05:46 UTC March 5, the PPS installed the V07C radar and combined algorithms. On March 5, the PPS will take the servers down (with the exception of near real-time) for system updates, with downtime potentially extending into the following day. Users will be unable to retrieve data during this downtime.

Since January 2024 the PPS has been running the GPM near-realtime (NRT) radar Ku, Ka, DPR and the combined products with an interim version of the post-boost radar algorithms. This was designated with the data product version V07X (experimental). JAXA and the radar algorithm team have developed the final post-boost V07 algorithm and will be delivering this on 5 March 2024. We will start using the new algorithms with the arrival of the V07C radar Ku/Ka 1B data from JAXA. The L2 Ku/Ka/DPR and combined products will then also change the data product version to V07C. The algorithm ID for combined

On 16 January 2024, JAXA MOS will begin sending an NRT version of L1B Ku and Ka radar. PPS NRT will begin producing L2 KU, KA, and DPR radar products. It will also begin producing combined GMI/radar products. All these products will have the data version V07X. The X is to designate that this is not the final code for radar products including boost adjustments but an early one to allow resumption of GPM NRT. The final version will arrive in March 2024. The algorithm versions for the radar products will also change. So, if you retrieve radar products based on file names, you should not use the
