GPM Examines Tropical Cyclone Gita Over Samoa

Recently formed tropical cyclone GITA was drenching Samo when the GPM core observatory satellite passed above on February 9, 2018 at 1426 UTC. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed the area and intensity of precipitation associated with the tropical cyclone. The area covered by GPM's radar swath is shown in lighter shades. GITA was producing heavy rainfall over a large area that included the islands. The center of the intensifying tropical cyclone was located just to the south of the islands. Rainfall in that area was

Weakening Tropical Cyclone Cebile Examined By GPM

The GPM core observatory satellite passed above weakening tropical cyclone CEBILE on February 6, 2018 at 1151 UTC. CEBILE's maximum sustained winds had decreased to about 40 kts (46 mph). The satellite showed that most of the convective rainfall in the sheared tropical cyclone was southeast of CEBILE's center of circulation. Dual Frequency Precipitation Radar (DPR) data received by GPM with this pass showed that the northeastern side of the eye wall was eroding while continuous heavy precipitation was found by GPM in the southeastern quadrant of the storm. The area scanned by GPM's DPR is

TRMM-era Constellation Level 2-Level 3 V05 Product release

With the evaluation and approval, PPS will start to process the TRMM era AMSRE, AMSUB and SSMI level 2 and level 3 GPROF products on Wednesday, February 7, 2018. Similar to the early released TRMM era MHS, SSMIS, AMSR2 and ATMS level 2 and level 3 products, all level 2 and level 3 GPROF products will be produced as GPM version V05, all products are in HDF5 format, all product names will use the GPM naming convention and the produced data will appear both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ after these are produced. All

GPM Probes Powerful Tropical Cyclone Cebile

Tropical Cyclone CEBILE formed four days ago in the southwest Indian Ocean southeast of Diego Garcia. Today CEBILE became the most powerful tropical cyclone to form in the southern hemisphere this year. Maximum sustained wind speeds within CEBILE were estimated at 120kts (138 mph) early today making CEBILE the equivalent of a category 4 hurricane on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite passed directly above the well defined circular eye of tropical cyclone CEBILE on January 31, 2018 at 0034 UTC. Rainfall intensity and coverage within CEBILE were revealed

GPM Views Sheared Tropical Cyclone Fehi

The GPM core observatory satellite flew tropical cyclone FEHI on January 30, 2018 at 0831 UTC. GPM revealed that precipitation was only located around the southern side of FEHI's circulation. Strong vertical wind shear had caused the surface center of circulation (shown with a red symbol) to be displaced well to the north of the heaviest rainfall. The satellite found that some convective storms on the southern side of the tropical cyclone were still producing very heavy precipitation. GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments revealed rainfall in a
