Jan. 2016 GPM IMERG and Jan.-Jun. 2016 TMPA 3B42/3B43 Data Products are Being Recalled and Replaced

UPDATE 9/27/16: January 2016 IMERG has been regenerated and posted. This was necessary due to an error that omitted the gauge analysis in the Final products. Also, 3B42/3B43 have been recomputed and posted. Let me know if you have any further questions. --- PPS has removed the January 2016 GPM IMERG and January through June 2016 3B42/3B43 TMPA products from our ftp archive: ftp://arthurhou.pps.eosdis.nasa.gov/ and STORM: https://storm.pps.eosdis.nasa.gov/storm/ The GPM science team discovered that the IMERG final products for Jan 2016 and the Jan-Jun 2016 TMPA 3B42/3B43 products for which we

GPM Transitioning its Web-based Global Displays

What: Google Earth access for near-realtime IMERG and 3B42 KML files will be replaced by an updated service for viewing precipitation data in near-real time on a 3D virtual globe using Cesium ( https://cesiumjs.org/). When: The current plan is to make the cut-over to the new Cesium-based service on or about October 16, 2016. Why: The evolution of network policies and applications prevents continued GPM use of Google Earth. Note: If you wish to continue using KML files with a non-Google Earth client, please contact the Precipitation Measurement Missions at: https://pmm.nasa.gov/contact

PPS Down for Maintenance Tuesday September 20, 2016

The PPS (Precipitation Processing System) will be down today, September 20,2016 from 8:00am -2:00pm EDT (12:00 - 18:00 UTC). for scheduled maintenance. During this time all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable. You may contact PPS Operations at 301-614-5247 , 301-614-5184 or fax us at 301-614-5269 if there are any urgent matters requiring our immediate attention during this period. You will be informed when PPS systems become available. We apologize for any inconvenience this may

SSMIS Outage Affecting TMPA and IMERG

FNMOC is behind in providing the SSMIS data used in IMERG. Therefore, the Early and possibly Late IMERG products will contain less satellite estimates and be of somewhat lesser quality. FNMOC stopped providing data around 00 UTC today (8 September 2016), meaning there has been no data available from the three operational SSMIS sensors to the TMPA-RT datasets. As a result, more lower-quality IR-based estimates are being used. In addition, if there are dropouts in the IR data, there is a higher probability that gaps will appear in the combined product, 3B42RT. We will update the situation when

Deadly Flooding Gulf Coast Rainfall Measured By NASA's IMERG

Deadly Flooding Gulf Coast Rainfall Measured By NASA's IMERG
An extremely severe rainfall event hit the states of Louisiana and southern Mississippi when a very slow moving low pressure system continuously pulled tropical moisture from the Gulf Of Mexico. Measurements by the GPM core observatory satellite showed that rainfall intensity within the low pressure system actually increased on August 12, 2016 as the low settled over southeastern Louisiana. At least 4 people have died in record flooding after the unusually heavy rainfall starting falling last week. More than 27 inches (686 mm) of rain have been reported in the area. This is the second time

Extreme Rainfall Along the Gulf Coast Measured by IMERG

Extreme Rainfall Along the Gulf Coast Measured by IMERG
For the better part of a week, a persistent, mid-level area of low pressure has been tapping into warm, moist air to produce stormy weather in the northeastern Gulf Of Mexico. The National Hurricane Center (NHC) monitored this stormy area for possible development but unfavorable upper-level winds and the close proximity to land prevented development into a tropical system. However, during the past week from as much as 4 to over 15 inches (254-381 mm) of rain fell along the Gulf Coast from Tampa northward through the Big Bend to as far west as central Louisiana. So far the highest rainfall

Deadly Hurricane Earl's Rainfall Measured With IMERG

Deadly Hurricane Earl's Rainfall Measured With IMERG
Hurricane Earl began as a tropical wave that was tracked by the National Hurricane Surface (NHC) from the African Coast to the Caribbean Sea. The tropical wave drenched the Dominican Republic where it was blamed for the deaths of six people. Southwest of Jamaica on August 2, 2016 the tropical wave developed a closed circulation and Earl was upgraded to a tropical storm. On Wednesday August 3, 2016 Earl became a hurricane when it was located about 150 miles east of Belize. On Thursday Earl made landfall just southwest of Belize City, Belize at about 0600 UTC (2 AM EDT). At landfall Earl had

IMERG Shows Darby's Rainfall Over The Hawaiian Islands

IMERG Shows Darby's Rainfall Over The Hawaiian Islands
Most of the Hawaiian Islands were spared serious damage from tropical storm Darby. The location of Darby's track through the Hawaiian Islands resulted in the islands of Hawaii and Oahu being the most affected. Flash flooding was common on Oahu due to a reported 177.8 mm (7 inches) of rain drenching the island. Interstate H-1 was flooded in some locations. Lightning damage was reported in Kaneohe on the windward side of Oahu. Estimates of rainfall accompanying tropical storm Darby were produced using NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data. These IMERG rainfall

Nepartak Causes Havoc Then Dissipates Over China

Nepartak was a powerful category four typhoon when it hit Taiwan last week but weakened to a tropical storm as it moved into the Taiwan Strait. Nepartak's winds and heavy rains caused severe problems when it moved ashore over southeastern China. Thousands of homes in China were destroyed by the storm. At least three deaths in Taiwan and six fatalities in China were attributed to Nepartak. Torrential rain caused flash flooding and mudslides in both Taiwan and China. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were again used to estimate the total amount of rain that Nepartak

Automating the Detection of Landslides

Monday, July 11, 2016
As farmers in Nepal prepare for the benefits of monsoon season, Dalia Kirschbaum anticipates the dangers of those torrential rains—mainly, the loosening of earth on steep slopes that can lead to landslides. In this mountainous country, 60 to 80 percent of the annual precipitation falls during the monsoon (roughly June to August). That’s when roughly 90 percent of Nepal’s landslide fatalities also occur, according to a 2015 report from the United Nations Office for the Coordination of Humanitarian Affairs. “We know a high number of landslides occur around this time, so documenting them is...
