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
