Fix to the Metadata of IMERG Climatology GeoTIFF Files

Recently, an error in the metadata of the GeoTIFF files for the IMERG V07B Final Run climatologies has been discovered. This error affected only the geolocation, specifically the orientation, of the fields and not the precipitation data. These files have been replaced with ones containing the correct metadata. Users who have downloaded the old GeoTIFF files should replace them with the new files. These IMERG climatology files are available at https://gpm.nasa.gov/data/imerg/precipitation-climatology

The joint NASA / JAXA Global Precipitation Measurement (GPM) mission has been tracking rain and snow around the globe for over 10 years, providing valuable insights into Earth's weather and climate. Now in its tenth year of operation, we look at ten events brought to light by this groundbreaking mission.
GPM Applications webinar banner
Did you know that GPM data has enabled people to better understand how water moves through our planet and make informed decisions that lead to improved outcomes for society? GPM continues to support a range of applications from water resource management, agriculture, vector- and water-borne disease monitoring, animal migration, tropical cyclone location and intensity estimation, hydropower management, flood and landslide monitoring and forecasting, and land system modeling, among others. Join us during this free webinar to learn about the multiple ways GPM is used throughout the world and gain a perspective from two GPM power users that help support weather forecasters and the ecological community.

On the morning of Sunday, June 30, Hurricane Beryl became a rare early season major hurricane when it reached Category 3 status with sustained winds of 115 mph as it was moving across the Atlantic 420 miles east-southeast of Barbados in the direction of the Leeward Islands. Then, just a few hours later at 11:35 a.m. EDT, Beryl became the earliest Category 4 hurricane on record in the Atlantic with sustained winds reported at 130 mph by the National Hurricane Center (NHC), surpassing Hurricane Dennis from the epic 2005 Atlantic hurricane season. Beryl also became historic as the strongest and

Status of IMERG Version 06 and 07 Data

The following is a clarification on the current status of Version 06 and Version 07 IMERG data. Production of V06 Early and Late datasets ceased on 3 June. After overcoming significant hardware, software, and data feed challenges, PPS instituted “Initial Processing” (that is, processing of new data) for Early and Late starting with 00:00 UTC on 1 June. “Retrospective Processing” (that is, processing of the record of previous data) is complete for Early from June 2000 through December 2023. Retrospective Processing is on-going for Late, with parallel runs starting with June 2000 and June 2014

JAXA Products Resume

At 01:45 UTC 12 June, JAXA resumed their processing of GPM radar products, which allowed PPS to catch up the downstream GPM DPR products that they compute, as well as computing the Combined product. Fortunately, through the processing outage the JAXA-NASA data line continued to operate, providing the ancillary data that GPROF and IMERG needed to continue uninterrupted near real-time processing.

GPROF and IMERG Production Continued, GPM Radar Still Unavailable

The PPS is now receiving AMSR2 data and JMA forecasts from JAXA, which means that GPROF and IMERG Early and Late products will continue being produced. The GPM radar and combined products are still unavailable due to the JAXA system issues. The PPS has also worked with partners at CSU to develop a new method of processing GPROF that will allow continued production even if no JMA forecast files are received, in the event of a future outage.

GPM Product Outages

Due to an unexpected JAXA system failure the PPS is not receiving GPM DPR Ku and Ka L1B data as well as AMSR2 data. As a result, the PPS cannot produce the GPM radar or combined datasets. The PPS is also not receiving JMA 6 hourly forecasts, and as a result after 12:00 UTC on June 11, 2024 the PPS will not be able to produce the GPROF or IMERG products. JAXA estimates that their systems will start running again by 03:00 UTC 12 June, at which point production of the above products at the PPS will resume.
