Replacement GPM Ka/Ku L1B products (2017-03-19) for orbit 17356

PPS received replacement GPM Ka/Ku L1B products from JAXA and will reprocess the affected data. If you have already obtained products with orbit #17356 from our archive or through a standing order, etc., please discard and use the replacement products. PPS has replaced the following GPM Ka/Ku L1B data: GPMCOR_KUR_1703190533_0705_017356_1BS_DUB_04A.h5 GPMCOR_KAR_1703190533_0705_017356_1BS_DAB_04A.h5 ------------------------------------- PPS will reprocess these affected downstream products shortly. 2A.GPM.Ka.V6-20160118.20170319-S053318-E070552.017356.V04A.HDF5 2A.GPM.Ku.V6-20160118.20170319

GPM Sees Powerful Convective Storms In The Timor Sea

The GPM core observatory satellite passed above some energetic storms in the Timor Sea north of Australia on March 20, 2017 at 0726 UTC. These powerful storms were being invigorated by very warm sea surface temperatures and low vertical wind shear aloft. Balmy water in the Timor Sea was reaching temperatures of 30 to 32 degrees Celcius (86 to 89.6 Fahrenheit). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that these storms contained some very heavy downpours. GPM's DPR found rain falling at a rate of over 238 mm (9.4 inches) per

Increased Latencies on GPM Products Due to TDRSS Safe Hold

On the afternoon of March 16, one of the TDRSS data relay satellites went into safe hold. This has reduced the relay satellites available for downloading the data from the GPM core satellite to the ground station at White Sands, NM. It means that times between download contacts have increased. No data is lost but data latency has been greatly affected for the GPM near-realtime core satellite products: GMI and DPR. We understand that this increase in latency will be the norm for the next couple of days. There are NO issues with the GPM core satellite or its sensors. Also there are NO issues

Tropical Cyclone's Remnants Examined By GPM

The GPM core observatory satellite flew above the remnants of tropical cyclone 11S on March 14, 2017 at 2356 UTC. The remnants were located south-southeast of Madagasgar and were rapidly transforming into an extra-tropical low. GPM showed the locations of intense rainfall still being produced by the low. GPM's Dual-Frequency Precipitation Radar (DPR) data showed that rain was falling at a rate of over 205 mm (8 inches) in a few storms. GPM's radar (DPR Ku Band) found that some storm tops in the remnants were reaching heights above 13 km (8 miles). GPM satellite radar (DPR Ku Band) data were

Tropical Cyclone Enawo's Rainfall Totals Updated With IMERG

Tropical cyclone Enawo is now responsible for the deaths of at least five people in Madagascar. Many thousands of people were also displaced due to flooding and destroyed homes. The tropical cyclone dropped heavy rainfall as it soaked the island from north to south. This rainfall analysis was updated to include recent precipitation estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) rainfall data. It shows rainfall estimates from IMERG data collected during the period from March 3-10, 2017. As expected, the eastern side of Madagascar had the highest rainfall total

IMERG V04 Early and Late Online

The algorithm for the Integrated Multi-satellitE Retrievals for GPM (IMERG) Early and Late Runs has now been upgraded to Version 04. The transition to V04 began at 15 UTC on March 13 and both the early and the late products were back to their target latency by 01:00 UTC, March 14. The transition took longer than planned but the core IMERG version 04 products are now running automatically as the original V03. The product version is V04A and you will see this in the name of the IMERG HDF5 products. For IMERG late the V03 products have remained before February 05, 2017. For IMERG early V03

Deadly Tropical Cyclone Enawo Drenches Madagascar

Tropical cyclone Enawo hit Madagascar on Tuesday with powerful winds and drenching rain. At least three people have been reported killed by the tropical cyclone. Floods and landslides are likely as Enawo moves southward down the center of Madagascar. Tropical cyclones rotate in a clockwise direction in the southern hemisphere so the eastern side of Madagascar will have a strong onshore flow. The extreme amount of moisture flowing onto Madagascar from the Indian Ocean is expected to produce flooding and landslides. NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data are produced

NASA Examines Deadly Spring-Like Weather With GPM Satellite

Rainfall from spring-like downpours in the U.S. from February 25 to March 1 were analyzed at NASA using data from the Global Precipitation Measurement mission or GPM satellite. This GPM rainfall image combined with infrared cloud data from NOAA's GOES-West satellite shows the line of storms that stretched from Pennsylvania to Alabama on March 1, 2017. Red areas indicate rainfall up to 50 mm per hour. Record breaking warm temperatures this winter have caused plants to bloom early in the eastern United States. Unfortunately this has also resulted in the formation of spring-like severe

Powerful Tropical Cyclone Enawo Threatens Madagascar

Tropical cyclone Enawo has continued to intensify while moving toward Madagascar. Enawo had winds of about 90 kts (103.5 mph) when the GPM core observatory satellite flew over on March 6, 2017 at 0306 UTC (0606 AM local time). These powerful winds make Enawo the equivalent of a category two hurricane on the Saffir-Simpson Hurricane wind scale. GPM revealed that the tropical cyclone had heavy rainfall in distinct feeder bands on the western side and in the northeastern side of the eyewall. Precipitation was measured by GPM's DPR falling at a rate of over 220 mm (8.7 inches) per hour in intense

Upcoming IMERG version update to V04A

The algorithm for the Integrated Multi-satellitE Retrievals for GPM (IMERG) Early and Late Runs has now been upgraded to Version 04. The transition to V04 is planned to happen on Monday, March 13 by 15 UTC at PPS and the new data should start flowing down to the GES DISC as well. Access and data fields continue to be the same as for Version 03, except the version number is 04A. Initially, the data records begin on 5 February 2017 for the Late Run, and about 5 hours before the time when PPS begins processing after the switchover for the Early Run. Version 04 supersedes all prior IMERG versions
