NASA Examines Deadly Spring-Like Weather With GPM Satellite

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

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

More Rain and Flooding in California

Another Pineapple Express Brings More Rain, Flooding to California
Wednesday, February 22, 2017
The West Coast is once again feeling the effects of the "Pineapple Express". Back in early January one of these "atmospheric river" events, which taps into tropical moisture from as far away as the Hawaiian Islands, brought heavy rains from Washington and Oregon all the way down to southern California. This second time around, many of those same areas were hit again. The current rains are a result of 3 separate surges of moisture impacting the the West Coast. The first such surge in this current event began impacting the Pacific coastal regions of Washington, Oregon, and northern California on...

GPM Examines Deadly Tropical Cyclone Dineo

GPM Examines Deadly Tropical Cyclone Dineo
Dineo has now weakened to a tropical depression but the tropical cyclone had winds of over 70 kts (80.5 mph) when it hit Mozambique. Four people have been reported killed by Dineo. The GPM core observatory satellite flew over Mozambique on February 16, 2016 at 0916 UTC after Dineo's maximum sustained winds had fallen to about 60 kts (69 mph). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that the tropical cyclone was still dropping light to moderate rainfall over a large area of southern Mozambique. This GPM view revealed that

Intensifying Tropical Cyclone Dineo Seen By GPM

Intensifying Tropical Cyclone Dineo Seen By GPM
Tropical cyclone Dineo was intensifying in the middle of the Mozambique Channel when the GPM core observatory satellite flew over on February 14, 2017 at 0926 UTC. Dineo had winds of about 55 kts (~ 63.3 mph) at the time of this GPM pass. Very heavy precipitation was found in feeder bands on Dineo's northeastern side. The most intense rainfall was measured by GPM's Dual-Frequency Precipitation Radar (DPR) falling at a rate of over 132 mm (5.2 inches) per hour in the intense storms in the northeastern quadrant of the tropical cyclone. GPM's radar (DPR Ku Band) sliced through the center of

GPM Satellite Reveals Intensity Of Powerful Storms In The Timor Sea

GPM Satellite Reveals Intensity Of Powerful Storms In The Timor Sea
The GPM satellite flew over a stormy area of the Timor Sea northwest of Australia on February 7, 2017 at 1926Z. GPM found that this stormy area contained some extremely powerful convective storms. GPM's Dual-Frequency Precipitation Radar (DPR) found that the most intense storms were dropping rain at a rate of over 268 mm (10.6 inches) per hour. Data received by GPM's Radar (DPR Ku Band) also revealed the 3-D anatomy of precipitation hidden inside these unusually powerful storms. GPM's radar found that these storm tops were pushing to altitudes greater than 19 km (11.8 miles). GPM radar data

GPM Sees Carlos Moving Past Reunion Island

GPM Sees Carlos Moving Past Reunion Island
The GPM core observatory satellite flew above tropical cyclone Carlos on February 7, 2017 at 1056 UTC. Carlos was moving past Reunion Island with maximum sustained winds estimated at 45 kts (51.8 mph). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data show that rain bands west of Carlos' center were producing heavy rainfall. GPM's DPR swath is shown in a lighter shade. DPR measured a few downpours in the bands west of the Carlos' center of circulation dropping rain at a rate of over 120 mm (4.7 inches) per hour. GPM's radar (DPR Ku Band) found that a few storm tops

Tropical Storm Carlos Forms

Tropical Storm Carlos Forms
Tropical storm Carlos formed in the Southwest Indian Ocean north of the French Islands of Reunion and Mauritius on February 4, 2017 (UTC). This ended an unusual drought of tropical cyclone formation in that part of the Indian Ocean that began in July 2016. NASA's GPM core observatory satellite flew above tropical storm Carlos on February 5, 2017 at 1056 UTC when Carlos had maximum sustained winds of about 45 kts (51.8 mph). GPM collected data that showed the intensity and structure of precipitation within Carlos. GPM's Dual-Frequency Precipitation Radar (DPR) measured rain falling at a rate of

GES DISC FTP to HTTPS Transition

The Goddard Earth Sciences Data and Information Services Center (GES DISC) will soon be completing its transition from FTP access to HTTPS access using NASA Earthdata Login. This transition will require GES DISC users to register with NASA Earthdata Login if they haven't already done so. To learn more about NASA Earthdata Login and registering for an account, please see https://wiki.earthdata.nasa.gov/display/EL/How+To+Register+With+Earthda… GES DISC will begin this transition starting Feb 13 2017, and expects to complete the transition mid-March.
