Early and Late IMERG IR Issues

Difficulties with accessing NOAA CPC 4-km Merged Global IR data resulted in the loss of IR data in IMERG Early Run for 12 November 12:00-21:30 UTC and 14 November 10:00-15 November 10:30 UTC, and in IMERG Late Run for 12 November 12:00-20:30 UTC and 14 November 10:00-15 November 09:30 UTC.  Subsequently, the IR data were retrieved for use in the Final Run.

Replacement GPM Ka/Ku L1B products 2019-11-06 orbit# 32319

PPS will replace GPM Ka/Ku L1B products from JAXA and will reprocess the affected data including Level 2 and 3 data. If you have already obtained products with orbit#32319 from our archive or through a standing order, etc., please discard and use the replacement products when available. 

PPS will replace the following GPM Ka/Ku L1B data: 

PPS Announcing Release of GPM L2-L3 CSH V06 Data Products

The Precipitation Processing System (PPS) has begun the TRMM and GPM Goddard Convective-Stratiform Heating (CSH) V06A level 2 and level 3 data reprocessing on, Monday October 21, 2019.  This reprocessing will cover the whole life for TRMM and the period from the launch to current for GPM.

The release notes (CHS V06) explaining the key changes from V05A and improvements implemented in the current V06A product will be available later this week and will be posted on the following PPS public web pages as soon as it's provided:

IMERG Sees a Dry September

IMERG Sees a Dry September

Rainfall was scarce across much of the country in the month of September, pushing the eastern and southern thirds of the country into drought conditions.  IMERG, the Integrated Multi-satellitE Retrievals for GPM, is a unified satellite precipitation product produced by NASA to estimate surface precipitation over most of the globe.  With IMERG, precipitation estimates from the GPM core satellite are used to calibrate precipitation estimates from microwave and IR sensors on other satellites.

Using the IMERG Long-term Precipitation Data for Applications

Using the IMERG Long-term Precipitation Data for Applications

A long precipitation data set like the new GPM IMERG V06 product is valuable for many applications and for decision-making. Accurate and reliable precipitation records are not only crucial to understanding trends and variability but also for water management resources and food security, ecological management, and weather, climate and hydrological forecasting. Here we present a few highlights showcasing how GPM IMERG is helping a variety of end users make decisions that will benefit society for years to come.

MHS NOAA-19 Data Processing Stop (PPS Will Resume NOAA-19 1C and GPROF Data)

PPS will resume to process NOAA-19 MHS L1C and GPROF products for the granules starting from 09/20/2019 10:22:10 UTC.
There was an issue with the satellite drifting which caused issues with the pre-processing. NOAA/NESDIS updated the processing coefficient and made the NOAA-19 MHS channel 2 L1B data back to normal.
