Heavy Rainfall Leads To Deadly California Mudslides

Winter rains falling on recently burned ground triggered deadly mudslides near Santa Barbara, California on the 9th of January. The potential for landslides is shown above. It was generated by the global Landslide Hazard Assessment for Situational Awareness (LHASA) model, a model that combines GPM precipitation data with a global landslide susceptibility map. LHASA gives a broad overview of landslide hazard in nearly real time, but site-specific information should be obtained prior to emergency operations or building projects. At least 15 residents of southern California have been killed by

Tropical Cyclone Ava's Disastrous Rainfall Measured With IMERG

Tropical cyclone Ava dropped extremely heavy rainfall over Madagascar as it passed over the eastern side of the island country from January 5-6, 2018. Ava's drenching rainfall caused flooding and landslides which resulted in the deaths of at least 29 people. An estimated 80,000 people on Madagascar were affected by the tropical cyclone. This rainfall analysis was produced by accumulating rainfall that fell near Madagascar during the period from January 2-8, 2018. These IMERG estimates showed the locations of extreme rainfall totals during the period when tropical cyclone Ava was in Madagascar

1 Dec 2017 installation of IMERG V05B

On 1 December 2017 sometime between 07:00 UTC and 12:00 UTC, PPS will begin installing V05B algorithms for the near realtime (NRT) IMERG dataset. If no problems arise, the installation should take approximately 4 hours. During this period IMERG products will be unavailable. While this is the first V05 IMERG available from NRT, we are making the data product version V05B so that both the early and the late product will be consistent with the version of the final product which is at V05B. To avoid unnecessary emails, PPS will not send out an email when the V05 installation is complete. Users

PPS is Releasing Version 05 GPM IMERG Final Products on Monday November 13, 2017

Starting on Monday November 13, 2017, PPS will generate Version 05 GPM IMERG Final products. The V05 IMERG Final products will be available both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ NASA requires that science users register at: https://registration.pps.eosdis.nasa.gov/registration/ to access PPS data services. PPS will reprocess the V05 IMERG Final products back to data date March 12, 2014. All users are encouraged to retrieve the V05 IMERG Final products to ensure that they use the most recent products. The V04 IMERG

Restart of NOAA-19 MHS in IMERG

25 October 2017 At about 4:57 UTC on 9 October 2017 the NOAA-19 MHS precipitation estimates started displaying artifacts, which was eventually traced to the instrument going into safe mode without shutting down data delivery. Since this happened over the long Columbus Day weekend, it took until 01:47 UTC on 10 October 2017 to shut down the data stream, so the Early and Late IMERG have these (very obvious) artifacts for almost 24 hours. No reprocessing is planned. The sensor resumed operations at 17:31:08 UTC on 16 October 2017, but because the basis for the safe mode was unknown, GPM chose to

Artifacts in Early and Late IMERG for 9-10 October

Starting with the first orbit of 9 October 2017, the MHS data from NOAA-19 began displaying substantial artifacts. After the orbit crossing 00 UTC 10 October, the NOAA-19 data have been embargoed from Early and Late IMERG, although it took until 03 UTC for all artifacts to age off the morphing. At this point, Early and Late IMERG appear nominal, except they lack the sampling that NOAA-19 provides.
Using NASA Satellite Data to Predict Malaria Outbreaks
In the Peruvian Amazon, the Anopheles darlingi mosquito is most responsible for spreading malaria. With funding from NASA's Applied Sciences Program, scientists are turning to the agency’s fleet of Earth-observing satellites to develop a system that uses satellite and other data to help forecast malaria outbreaks at the household level months in advance and prevent them from happening. Credits: NASA's Goddard Space Flight Center / Joy Ng In the Amazon Rainforest, few animals are as dangerous to humans as mosquitos that transmit malaria. The tropical disease can bring on high fever, headaches...

Irma’s Heavy Rainfall Measured With GPM IMERG

Hurricane Irma dropped extremely heavy rain at times during it’s trek from near the Cape Verdi Islands through the northern Leeward islands, Cuba and the southeastern United States. Over 16 inches (406 mm) of rain was reported in Guantanamo, in the easternmost province of Cuba, as the category five hurricane battered the country. Almost 16 inches (406 mm) of rain was also reported at Fort Pierce on the eastern side of Florida. Charleston, South Carolina reported 6 inches (152.4 mm) of rain in 24 hour. This heavy rainfall plus storm surge flooding caused the worst flooding in Charleston since

Deadly Southern Asia Flooding Rainfall Measured By NASA's IMERG

Deaths of over 250 people have resulted from extremely heavy monsoon rainfall in parts of northern India, Bangladesh and Nepal. The death toll from flooding and landslides is expected to continue increasing. Heavy monsoon rainfall is normal in southern Asia this time of year but precipitation totals this year are higher than expected. Recent heavy rainfall is also causing the Brahmaputra and Ganges Rivers rivers to continue rising. This rainfall analysis over southern Asia was created using IMERG real time data covering the period from August 10-16, 2017. Total rainfall IMERG estimates of over

NASA's IMERG Shows Cindy's Extreme Rainfall

Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017. Flooding was reported along the the Gulf Coast even before Cindy made landfall. The rainfall around tropical storm Cindy was asymmetrical. The majority of heavy rainfall with the tropical cyclone was located east of Cindy's center in the states along the Gulf Coast from Louisiana through the Florida Panhandle. The tropical depression continued to spread heavy rain and occasionally severe thunderstorms after it came ashore. Severe thunderstorms spawned
