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.

GPM Sees Possible Tropical Cyclone Developing Near Australia

GPM Sees Possible Tropical Cyclone Developing
So far this year no tropical cyclones have developed in the Southwest Indian Ocean. The Joint Typhoon Warning Center (JTWC) recently warned that a low moving westward over northwestern Australia may soon become a tropical cyclone. Warm Indian Ocean waters and low vertical wind shear are providing a good environment for tropical cyclone development. The GPM satellite flew over northwestern Australia on January 25, 2017 at 2351 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) measured precipitation within strong convection in the Indian Ocean northwest of the lows

Mudslides & Flooding Produced By Extreme Rainfall Over Southern California

Mudslides & Flooding Produced By Extreme Rainfall Over Southern California
It is sunny in southern California today but recent unusually heavy rainfall led to rock slides, mudslides and flooding in that part of the country. Rainfall of almost 4 inches (101.6 mm) in one day was reported in Long Beach, California. Some highways in the area were flooded due to intense downpours. Rainfall since the fall of 2016 has improved drought conditions over northern California but Southern California has been slower to improve because of the exceptional rainfall deficit in that area. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the total

Atmospheric River Slams California

Atmospheric River Slams California
Monday, January 23, 2017
After more than four years of drought, Californians may wonder where the current rain is coming from. Using satellites, NASA scientists have a unique view of the sources of precipitation, and how it reaches the western United States. Rain is often carried by narrow tendrils of moisture called atmospheric rivers that occur all over the world, shown here in white. The atmospheric rivers that affect the western United States are known as the Pineapple Express because they transport water vapor from as far south as Hawaii to California. When the moisture reaches land, it is forced up over the...

Deadly Torrential Rain Hits Southern Thailand

Deadly Torrential Rain Hits Southern Thailand
Widespread flooding has recently caused the deaths of dozens of people in southern Thailand. Frequent and persistent downpours have resulted in record rainfall totals. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the total amount of rain that fell over southern Thailand during the past week. Extreme rainfall totals of over 700 mm (27.6 inches) were shown over the Gulf of Thailand. The highest rainfall total estimates over land were greater than 500 mm (19.7 inches) on the eastern coast of the Malay Peninsula in the Bang Saphan district. Rainfall has

Pineapple Express Delivers Heavy Rains, Flooding, Drought Relief to California

An atmospheric river (“Pineapple Express”) delivered over 5 inches of rainfall in parts of California during January 3-10, 2017 (bottom) as viewed by GPM’s IMERG data.
An atmospheric river (“Pineapple Express”) delivered over 5 inches of rainfall in parts of California during January 3-10, 2017 (bottom) as viewed by GPM’s IMERG data. California, which has long been suffering through a strong, multi-year drought, is finally beginning to see some much needed relief as a result of a recent series of storms that are part of a weather pattern known as the “Pineapple Express.” The Pineapple Express is known as an atmospheric river. A large, slow-moving low pressure center off of the West Coast taps into tropical moisture originating from as far south as the

Deadly Tornadoes & Flooding Hits The Southeast

Deadly Tornadoes & Flooding Hits The Southeast
Severe thunderstorms spawned tornadoes and generated flooding rainfall over the Southeast on Monday evening. At least twelve tornadoes were reported with twisters spotted in Mississippi, Alabama and Georgia. Four deaths in Alabama and one in Florida have been blamed on this violent weather. Total rainfall was measured from December 30, 2016 through early January 3, 2017 using precipitation estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data. IMERG data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the

Typhoon Nock-ten's Rainfall Measured By IMERG

Typhoon Nock-ten's Rainfall Measured By IMERG
Heavy rainfall and winds from super typhoon Nock-ten caused the deaths of at least six people as it roared through the Philippines. Data generated by NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the total amount of rain that super typhoon Nock-ten dropped as it approached and traveled over the Philippines. Nock-ten’s approximate locations and appropriate tropical cyclone symbols at 0000Z and 1200Z are shown overlaid in white on IMERG rainfall estimate images. This IMERG analysis shows estimated rainfall totals using NASA's IMERG data produced during the
