GPM

GPM Transitioning its Web-based Global Displays

What:
Google Earth access for near-realtime IMERG and 3B42 KML files will be replaced by an updated service for viewing precipitation data in near-real time on a 3D virtual globe using Cesium (https://cesiumjs.org/).

When:
The current plan is to make the cut-over to the new Cesium-based service on or about October 16, 2016.

Why:
The evolution of network policies and applications prevents continued GPM use of Google Earth.

Hurricane Patricia Makes Landfall in Mexico

The eye of hurricane Patricia hit the Mexican coast on October 23, 2015 at approximately 6:15 PM CDT(2315 UTC)near Cuixmala, Mexico. The maximum winds at that time were estimated to be 143 kts (165 mph). Patricia is weakening rapidly but continued heavy rain is expected to cause flash floods and mudslides in the Mexican states of Nayarit, Jalisco, Colima, Michoacan and Guerrero through Saturday October 24, 2015. Over the weekend the remants of Patricia are also expected to add to the extreme rainfall in Texas.

NASA Aids Response to Carolina Flooding

NASA Aids Response to Carolina Flooding

It was rain that wouldn't quit. A weather system fueled by warm moisture streaming in from the Atlantic Ocean on Oct. 3 and 4 relentlessly dumped between one and two feet of rain across most of South Carolina. The result was rivers topping their banks and dams bursting. Catastrophic flooding followed across most of the state, which has left residents in some areas without power or clean drinking water.

GPM In Position to Watch 2015’s El Niño

Global Precipitation Measurement (GPM) Is In Position to Watch Effects of 2015’s El Niño

Since late in 2014, scientists in many different disciplines (including meteorologists, climate scientists, physical and biological oceanographers, hydrologists, and geologists) have been watching a slow-to-develop El Niño even in the tropical Pacific Ocean. After teasing observers with conditions that did not quite meet El Niño criteria1, the event finally reached official El Niño status in March and April, and is now expected to become a powerful event lasting into the next Northern Hemisphere winter.

Improving Flood Predictions With GPM

Satellite-Based Flood Monitoring Central to Relief Agencies' Disaster Response

In January 2015, the Shire River in Malawi, and Zambezi River in Mozambique were under tight scrutiny. Weeks of torrential rains led these and other rivers to burst their banks displacing 390,000 people across the region. In southern Malawi 220,000 acres of farmland were turned into a lake, cutting off roads and stranding thousands of people on patches of high ground. The flood was devastating for the country, but within 72 hours of it being declared an emergency the United Nations World Food Programme (WFP) was on the ground distributing food to residents.

Large Gap in Near-Realtime Data

Starting at 08:38 UTC PPS stopped getting data from the GPM Mission Operations Center.  Data was resumed at 17:21 UTC.  However, new GPS data was sent before older GPS data. The science data was sent out of order with the GPS data. This meant that about 125 mins of 1B and 1C GMI data had no geolocation and perhaps more after this had questionable geolocation. The same issues obviously also affected the radar and combined NRT which are just missing for the period between 8:30 UTC and 17:30 UTC.

Engaging Citizen Scientists With GPM

Engaging Citizen Scientists With GPM

Every morning at seven, Andrew Welch wakes up, cooks breakfast and checks the rain gauge sitting on a five-foot post in his backyard. He writes down the measurement, sends his kid off to school and then heads out to his workplace as a structural engineer.

Welch is a citizen scientist. Around the world, hundreds of citizen scientists like him are collecting precipitation measurements from the ground that are useful for NASA’s Global Precipitation Measurement (GPM) mission.

A GPM View of Tornado Spawning Thunderstorms

Twelve tornado sightings reported to NOAA yesterday were associated with severe thunderstorms extending from the Texas Gulf coast, through Oklahoma and Kansas. The GPM core observatory satellite had a good look at this area of severe weather on April 17, 2015 at 0003 UTC (April 16, 2015 at 7:03 PM CDT). A precipitation analysis using GPM's Microwave Imager (GMI) shows that some of these severe storms were dropping rain at a rate of over 86 mm (about 3.4 inches) per hour.
