GPM Level 1 Constellation Processing will Commence Friday Oct. 06, 2017

With the completion of the TRMM version 8 level 1 processing, PPS will start to process the TRMM era GPM constellation level 1 data on Friday October 6, 2017. Similar to the TRMM version 8 level 1 product, all level 1 constellation products will be produced as GPM version V05, all products are in HDF5 format, all product names will use the GPM naming convention and the produced data will appear both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ PPS will reprocess the entire TRMM era constellation data. All users are encouraged to

Level 2- Level 3 GPROF for MHS, NPP Partner Data transitioning to Version 05C (V05C)

Starting with data date October 01, 2017, the Level 2-Level 3 GPROF data for METOPA, METOPB, NOAA18, NOAA19 (MHS) and NPP ATMS partner products will be running new code and produced as product version V05C. These code changes are relatively minor and primarily affect the outer edges of the swath. Processing of the V05C data will start tomorrow on Wednesday October 04, 2017. Notable changes include : ------------------------------------------- The V05C GPROF of the Cross-track sensors allows for more usable pixels on the outside of the MHS and ATMS scans as compared to the previous version.

Replacement GPM Ka L1B products (2017-09-29) for orbit 20378

PPS received new GPM Ka L1B products (2017-09-29) for orbit 20378 from JAXA and reprocessed the affected data. If you have obtained any of these products from our archive or through a Standing Order, etc., please discard these and use the replacement products. The following files and corresponding browse products will be replaced 2AKa 2A.GPM.Ka.V7-20170308.20170929-S121703-E134937.020378.V05A.HDF5 2ADPR 2A.GPM.DPR.V7-20170308.20170929-S121703-E134937.020378.V05A.HDF5 2BCMB 2B.GPM.DPRGMI.CORRA2016.20170929-S121703-E134937.020378.V05A.HDF5 2HCSH 2B.GPM.DPRGMI.2HCSHv3-1.20170929-S121703-E134937

TRMM Version 8 Level 1 Reprocessing Will Start Monday Oct. 02, 2017

PPS will start the TRMM version 8 level 1 processing on Monday October 2, 2017. All products will be produced as GPM version V05. All the TRMM products are in HDF5 format with internal compression (same as the current GPM products), and will be produced using the PPS Toolkit (TKIO) version 3.80.29. The TRMM product names will be changing using the GPM naming conventions. The GPM naming convention document can be found at: https://pps.gsfc.nasa.gov/Documents/FileNamingConventionForPrecipitatio…. TRMM version 8 level 1 products have new identifiers, 1ATMI, 1BTMI, 1AVIRS

Sept 26-Sept 29 GPM NRT Radar outage

On September 26 at about 14:45 UTC the GPM radar was commanded to undertake an experimental Ka scanning approach. As the radar is not in normal observational mode no normal observational data is being generated from either the Ku or the Ka radar. This situation will continue until approximately 14:40 UTC on 29 September 2017 when the radar will be commanded back to its observational scanning approach.

GPM Views Weakening Hurricane Maria

GPM Views Weakening Hurricane Maria
Hurricane Maria has significantly weakened from the powerful category four hurricane that devastated Puerto Rico. The GPM core observatory satellite flew over Maria on September 25, 2017 at 9:28 PM EDT (September 26, 2017 at 0128 UTC). This informative GPM pass showed that the western side of the hurricane was drier and contained much less precipitation than the eastern side. GPM's Dual-Frequency Precipitation Radar (DPR) scanned directly through the center of Maria's eye and showed that there were only light to moderate rain showers around the hurricane's center. DPR found a few convective

GPM Shows Hurricane Maria North Of Turks And Caicos Islands

GPM Shows Hurricane Maria North Of Turks And Caicos Islands
On September 23, 2017 at 8:12 AM AST (1212 UTC) the GPM core observatory satellite had another excellent view of hurricane Maria. The early morning view showed Maria heading north of the Bahamas after battering the Turks and Caicos Islands. Maria had maximum sustained wind speeds of about 121mph (105 kts). Estimates of hourly rainfall at the ocean's surface were derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data. Multiple intense rainfall bands are shown rotating around the western side of the hurricane. Rain was found falling at a rate of over 6.57

Hurricane Maria's Torrential Rainfall Measured By IMERG

Hurricane Maria's Torrential Rainfall Measured By IMERG
Hurricane Maria has caused catastrophic flooding in Puerto Rico. Extreme flooding was reported in the streets of San Juan, the capital of Puerto Rico. The National Weather Service issued flash flood warnings for the entire island. Hurricane Maria has now moved to the northwest of Puerto Rico but is still expected to contribute to rainfall over the island on Friday. Feeder bands are transporting rain over Puerto Rico and the Dominican Republic even as the hurricane moves toward the Turks and Caicos islands. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to estimate

GPM Sees Hurricanes Maria and Jose

GPM Sees Hurricanes Maria and Jose
Wednesday, September 20, 2017
GPM passed over both Hurricane Maria and Hurricane Jose on September 18th, 2017. As the camera moves in on the Maria, DPR's volumetric view of the storm is revealed. A slicing plane moves across the volume to display precipitation rates throughout the storm. Shades of green to red represent liquid precipitation extending down to the ground. The Global Precipitation Measurement (GPM) mission shows the rainfall distribution for two major storms churning in the Atlantic and Caribbean basins. The visualization shows Hurricane Jose as it continues to slowly move northward off the US East Coast east...
