GPM IMERG V06A is being retracted for correction

An error has been discovered in processing the initial batches of V06 IMERG Final Run months.  A design choice in the code ended up retaining microwave precipitation estimates in the latitude band 60°N-S when there is snow/ice on the surface, rather than masking out the estimates due to low performance in such cases.  [Masking for microwave retrievals over surface snow and ice outside that band is correct.]

PPS Announces GPM IMERG V06 Data Availability Starting after 3/13/2019

Starting  this week (Wednesday March 13, 2019 or soon after) PPS will commence GPM IMERG data reprocessing for IMERG V06.  PPS will start reprocessing with the GPM-era data and will make these products available as they are archived.

Thereafter, we will reprocess the TRMM-era data.  The first available products for the GPM-era will start with June 2014. TRMM-era products will span June 2000 - May 2014.   Earlier TRMM-era processing, 1998-01 to 2000-05, will proceed when all required input data have been provided.

PPS Announces Level 2- Level 3 PRPS MT1 SAPHIR V06 reprocessing

PPS will be doing a full reprocessing of Level 2 - Level 3 PRPS MT1 SAPHIR data as V06A for release starting Wednesday March 06, 2019.  In addition to the regular data products there will be a Climatology product as with the current L2-L3 GPROF data products.  The following data will be reprocessed as V06A:

PPS Announcing Data Product Version Change for GPM Level 2 and Level 3 GPROF Data -Available Starting Mon Feb. 04, 2019

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.

Change in letter on GMI NRT GPROF data products

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.

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas

Heavy precipitation has been falling in areas of California that were recently devastated by deadly wildfires. This flooding rainfall has resulted in evacuations in burn scarred areas such as Butte County where the deadly Camp Fire hit this month. Flash floods, debris flows and mudslides are now predicted in areas where deadly wildfires stripped away vegetation. On a positive note these Pacific storms are expected to dampen wildfires and replenish the Sierra Nevada snowpack. This snowpack is an important source of water for California's streams and rivers.

NASA's IMERG Used To Analyze Tropical Storm Usagi's Rainfall

Usagi strengthened to hurricane intensity as it approached Vietnam from the South China Sea but weakened to tropical storm intensity when coming ashore. Very heavy rainfall and damaging winds accompanied tropical storm Usagi when it hit Vietnam's southern coast. More than 350 mm (14 inches) of rainfall was reported causing widespread flooding around Ho Chi Minh City.
