GPM

NASA's GPM core observatory satellite flew above tropical storm FABIO in the eastern Pacific Ocean south of Mexico on June 30, 2018 at 10:46 PM MDT (July 1, 2018 at 0446 UTC). FABIO has continued to intensify since then and the National Hurricane Center (NHC) predicts that the tropical storm will become a hurricane later today. FABIO is then expected to become a major hurricane on July 3, 2018 and reach it's peak intensity with wind speeds of about 105 kts (121 mph). Rainfall measurements by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that FABIO

Tropical depression 09W was located in the northwest Pacific east of the Philippines when it was upgraded today to tropical storm PRAPIROON. The tropical storm is in a favorable environment for intensification. Vertical wind shear is low above the tropical cyclone and sea surface temperatures are warm below. NASA's GPM core observatory satellite had a good view of tropical storm PRAPIROON on June 29, 2018 at 0246 UTC. PRAPIROON was just barely a tropical storm with maximum sustained wind speeds estimated at about 35 kts (40.3 mph). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation

PPS is releasing version 3.80.44 build of the PPS TKIO toolkit using the 14.0.1 Fortran compiler for GPM. As detailed in our earlier announcement that you received on Thursday, June 28th, 2018, titled; "PPS is Reprocessing TRMM PR Data as TRMM GPM, Version 06A HDF5 products in Early July 2018" This is the version of the PPS I/O Toolkit that will be used for these radar products. The release notes are in this directory and are also attached to this Email: ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.80.44/ The tar file can be found at: ftp://gpmweb2.pps.eosdis.nasa.gov/pub

The TRMM Version 7 Precipitation Radar (PR) products will be superseded by new GPM era products with a reprocessing that will generate TRMM retrievals from the beginning of the TRMM mission to the end of data collection using a single frequency retrieval algorithm similar to that used for GPM Ku. This reprocessing will begin in early July, 2018. Retrievals previously available in the TRMM Version 7 products 2A21, 2A23, 2A25, and 3A25 will be available in the new 2APR and 3PR products. Note that these new GPM era products are in HDF5 format and similar in structure to those used for GPM DPR

The GPM Core observatory satellite's passed over Oklahoma on Monday, June 25, 2018 04:08 AM CDT (0508 UTC). The satellite makes measurements of precipitation with it's GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments every 95 minutes as it orbits the earth at 252.3 miles (407 km). The area covered by GPM's radar is shown in lighter shades. GPM passed directly over the center of a Mesoscale Convective System (MCS) that was moving across Oklahoma. GPM found that the MCS contained some intense storms. GPM's DPR can make accurate rainfall measurements along it

Extremely heavy rainfall caused a flash flood emergency over southern Texas this week. More than 15 inches (381 mm) of rain fell in Hidalgo County, Texas since Tuesday June 19, 2018. The Governor of Texas declared a state of emergency for six counties in South Texas Thursday afternoon. Heavy rain had ended Friday morning but occasional showers were still occurring over southern Texas. At 4:28 AM CDT Friday June 22, 2018 the National Weather Service in Brownsville, Texas issued a "Flood Warning for Urban Areas and Small Streams in... Southwestern Hidalgo County in Deep South Texas..."

A mid-level and surface trough over southern Texas is producing heavy rainfall. Heavy rainfall is expected to continue in the area through Wednesday evening. On June 19, 2018 at 3:37 PM CDT ( 2037 UTC) the GPM core observatory satellite passed over the western Gulf Of Mexico. This GPM pass revealed extreme rainfall that was being produced by a tropical disturbance in the northwestern Gulf Of Mexico. GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments probed powerful storms that were dropping rain at a rate of 3.5 inches (88 mm) per hour. The GPM satellite's

Beneficial rainfall from hurricane Bud's remnants has spread into the Desert Southwest. This rainfall may be helpful in an area that has been experiencing exceptional drought accompanied by wildfires. Bud's rainfall may also signal the beginning of the summer monsoon over the Desert Southwest. The image above shows estimates of accumulated rainfall using IMERG (Integrated Multi-satellitE Retrievals for GPM) data generated during the period from June 9-18, 2018. This rainfall occurred during the period when Bud formed southwest of Mexico, intensified into a powerful category four hurricane

On Sunday June 17, 2018 PPS System Programmers and staff will be performing an important scheduled GPM archive server upgrade. Due to this upgrade process, most PPS systems and services will be unavailable for most or all of that day starting at 9:00 AM (EDT) and lasting until late afternoon or longer depending upon the upgrade circumstances. -It is important to note that GPM (NRT) near realtime services (SDPS and ftp://jsimpson.pps.eosdis.nasa.gov/) will remain available and unaffected during this period. -PPS's Aeolus server ( ftp://aeolus.pps.eosdis.nasa.gov/) will only provide near real
