PPS has created a new PPS/GPM Science Algorithm Toolkit (TKIO) package which includes all the latest production formats. Those wishing to access new production data products listed below using C and Fortran interfaces may wish to download this TKIO package. Those using development TKIO versions that include the newer products do not need this public distribution, it is optional. This 3.97 TKIO includes all production formats including the recent additions of the V06X radar products and 3B42/3 in HDF5.

Commencing today, Wednesday January 29, 2020, PPS is producing and releasing new satellite METOPC MHS GPM Level 1C and GPROF METOPC MHS GPM Level 2 and Level 3 data and Climatology Products V05. These new products will have the starting date of December 11, 2019. GPROF METOPC MHS GPM Level 2 and Level 3 Climatology products will be produced once the ERA5 input data is received for December 2019. See the tables below for pertinent details.

On February 20th and 21st, 2020, a winter storm brought the seasons largest snowfall to much of North Carolina and southern Virginia. The highest snow totals of 3-5 inches (7-12 cm) were located in northeast NC and southeast VA. GPM's radar captured captured the reflectivities shown in this cross-section as it flew over the snow storm on February 20th, with snow and frozen precipitation shown in blue and purple and rain shown in green and yellow. The melting layer marks the transition from snow to rain and slopes upward 2-3 km from central NC to the coast. These raw reflectivity measurements

GPM observed the early stages of a strong cyclonic system that developed over northern Africa just off the southern Mediterranean coast on March 11, 2020. The GMI measured heavy rain rates over some parts of Egypt, including the region around Cairo. View fullscreen By March 12, 2020, the cyclonic system that developed over northern Africa had intensified and was nicknamed 'The Dragon' on social media and news outlets, as it caused severe flooding in northern Egypt. Both the GMI and the DPR measured heavy rain rates across two of the storm's bands in this GPM overflight. View fullscreen On

By Friday morning, September 20, the rainfall from the remnant of Tropical Storm Imelda had increased to over 24 inches in some areas near the Gulf of Mexico coast between Beaumont and Houston, Texas. This rainfall was in excess of what had been forecasted a few days earlier and was due to Imelda's forward motion ceasing for approximately 24 hours between Wednesday and Thursday afternoon. The image shows, with large "L" symbols, the location estimated by the National Hurricane Center for Imelda's low-pressure center of rotation at various times over the past three days. This near-realtime rain

In the two weeks that followed December 25, 2019, several heavy storm systems impacted countries along the eastern Mediterranean. The NASA IMERG data product revealed the pattern of heavy rain accumulation over sea and land in near realtime.

Hurricane Dorian (2019) brought heavy rain to the Caribbean, along the US East Coast, and up to Canada. NASA satellite-based precipitation estimates tracked the storm throughout its lifetime, as shown by the sequence of images below. September 3, 2019: Hurricane Dorian over Grand Bahama and Abaco Islands In the early hours of Tuesday, September 3, Hurricane Dorian had been stationary over the island of Grand Bahama for 18 hours, most of the time as a category 5 hurricane. Storm-total rain accumulation over parts of Grand Bahama and Abaco islands have exceeded 24 inches according to NASA

UPDATE 2/12/2020: An extended IMERG analysis of rainfall in Brazil shows even more extreme rainfall occurring in the first weeks of February, with large regions experiencing rainfall totals over 18 inches since the start of 2020. According to local authorities, the region has already received 98% of the rainfall that is typically expected to fall during all of February. UPDATE 1/30/2020: During January 2020, parts of the Brazilian states of Minas Gerais and Espirito Santo experienced above average rainfall, causing deadly floods in the region. Part of the month's heavy rainfall came from a

Periodically, Harold's core region produced precipitation rates in excess of 30 millimeters
