PPS is Reprocessing TRMM PR Data as TRMM GPM, Version 06A HDF5 products in Early July 2018

The TRMM Version 7 Precipitation Radar (PR) products will be superseded by new GPM era products with a reprocessing that will generate TRMM retrievals from the beginning of the TRMM mission to the end of data collection using a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

Oklahoma Mesoscale Convective System (MCS) Examined With GPM

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

Southern Texas' Flooding Rainfall Examined With IMERG

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..."

GPM Satellite Probes Storms In The Western Gulf Of Mexico

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

Hurricane Bud's Rainfall Measured with GPM IMERG

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
