Tropical Storm Otto Develops, Threatens Central America

Tropical Storm Otto Develops, Threatens Central America
Tropical storm Otto formed in the southwestern Caribbean north of Panama on November 21, 2016. The GPM core observatory satellite had an excellent daytime view of the newly formed tropical storm on November 21, 2016 at 1906 UTC (2:06 PM EST). Otto had wind speeds estimated at 45 kts (52 mph) at that time. GPM satellite rainfall data are shown overlaid on a visible and infrared image captured by the GOES-EAST satellite at 1915 UTC (2:15 PM EST). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) revealed that the newly formed tropical storm had deep convective bursts in

PMM Publisher API Documentation

GPM flying over Earth with a data swath visualized.
Friday, November 18, 2016
Overview The PMM Publisher API can be used to automatically retrieve precipitation and related applications datasets and associated metadata for further processing by your tool of choice. Here we will outline the basic structure of requesting data from the API and interpretting the API response. Initial Request The initial request will return a collection of datasets (in the form of a structured JSON object) that match to the parameters you specify, including associated metadata about each dataset. You can then use the actions specified within the object returned to download the actual data...

Deadly Tropical Rainfall Examined by IMERG

Deadly Tropical Rainfall Examined by IMERG
Scattered to numerous showers and scattered thunderstorms have occurred over Hispaniola during the past week. Slow moving frontal systems draped over Hispaniola and a tropical wave recently caused heavy rainfall that led to wide spread flooding over the northern Dominican Republic. Over 20,000 people have been displaced from their homes and at least five deaths have been reported. A broad area of low pressure (90L) in the southwestern Caribbean is also being monitored for possible tropical cyclone development by the National Hurricane Center (NHC). Very warm sea surface temperatures and upper

Tropical Depression MA-ON Evaluated With GPM Data

Tropical Depression MA-ON Evaluated With GPM Data
Tropical cyclones have been forming frequently in the Western Pacific Ocean since July 2016. 36 named tropical cyclones have formed in the Western Pacific in less than 5 months with 14 of them becoming typhoons. Tropical Depression MA-ON Formed on November 10, 2016 northeast of Guam. MA-ON had maximum sustained winds estimated at 30 kts (34.5 mph) when the GPM core observatory satellite flew over on November 10, 2016 at 0701Z. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that the tropical depression contained some very heavy showers. Strong bands

Tropical Disturbance Threatens India and Bangladesh

Tropical Disturbance Threatens India and Bangladesh
A tropical disturbance that recently formed in the Bay Of Bengal may cause heavy rainfall in the next few days along coastal India's eastern state of Odisha and southern Bangladesh. The low is predicted to move northeastward over the warm waters of the Bay Of Bengal but according to the Joint Typhoon Warning Center (JTWC) has only a medium chance of developing into a tropical cyclone. High vertical wind shear is forecast to keep the tropical disturbance from intensifying. The GPM core observatory flew above the low on November 4, 2016 at 0026 UTC. GPM saw that the low contained some strong

Deadly Storms Hit Egypt

Deadly Storms Hit Egypt
Last week severe storms hit Upper Egypt and areas along the Red Sea coast on October 26 and 27, 2016. Egypt normally receives relatively little rain and the heaviest rainfall usually occurs along the Mediterranean coast. Heavy rainfall from intense storms led to flooding in parts of Egypt including the Sohag and Bani Suef in Upper Egypt, the Southern Sinai and the Red Sea. At least 26 deaths and 72 injuries were attributed to the storms. The GPM core observatory satellite routinely passes above that area with a very informative pass occurring on October 27, 2016 at 0541 UTC. Data collected by

Typhoon Haima Hits China After Devastating The Northern Philippines

Typhoon Haima Hits China After Devastating The Northern Philippines
After Haima's caused extensive destruction and at least 13 deaths in the northern Philippines the typhoon traveled across the South China Sea to batter Hong Kong and mainland China. Heavy rain and gusty winds accompanied Haima as the typhoon passed to the east of Hong Kong. Operations at Hong Kong's international airport were nearly stopped by the typhoon. At least one person was reported killed in Hong Kong. Haima made landfall in China 110 km (68 miles) east of Hong Kong at about 0400 UTC (noon CST). Haima's winds were decreasing and the typhoon was the equivalent of a category one hurricane

GPM Measures Extreme Rainfall With Typhoons Sarika and Haima

GPM Measures Extreme Rainfall With Typhoons Sarika and Haima
Two powerful typhoons have hit the Philippines in less than a week. The first was Typhoon Sarika (known as Karen in the Philippines) that formed east of the Philippines on October 12, 2016. Sarika intensified and had peak sustained winds of 115 kts (132 mph). This wind speed made it the equivalent of a category four on the Saffir-Simpson hurricane wind scale. Sarika made landfall in the Philippines on Sunday in the northern province of Aurora on the island of Luzon. Three people were killed as Sarika pounded the Philippines with heavy winds and flooding rainfall. After hitting the Philippines

GPM Looks at Rainfall in Remnants of Songda Over Pacific NW

NASA Looks at Rainfall in Remnants of Songda Over Pacific NW
The Global Precipitation Measurement mission or GPM core satellite saw heavy rain with rates of around 50 mm/hr (~2 inches/hr shown in dark red) in the front that absorbed the remnants of former northwestern Pacific Ocean Typhoon Songda. These images were created from data taken on Saturday, Oct. 15 as the front was affecting the U.S. Pacific Northwest. The rain is depicted in red and green areas, indicating heavy, moderate and light rain, respectively. Images produced by Jacob Reed (Telophase/NASA GSFC) and caption by Rob Gutro (GSFC)

Hurricane Nicole Moving Over Cold North Atlantic

Hurricane Nicole has now been active for almost two weeks. Nicole was still a hurricane with winds of about 70 kts (81 mph) when the GPM core observatory satellite flew over on October 17, 2016 at 0436 UTC (2:36 am EDT). The GPM satellite had a good look at the rainfall in Nicole's large ragged eye. GPM's Dual-Frequency Precipitation Radar (DPR) swath sliced through the center of Nicole's eye and found some very heavy rainfall. A few strong storms in the southern side of the eye were dropping rain at a rate of over 113 mm (4.4 inches) per hour. GPM's radar (DPR KU band) data collected with
