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.
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.
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.
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.
PPS has completed the production of the GIS-friendly TIF/TFW products created from the IMERG Early dataset. These products include running accumulations at 3hr and 1day.
The Early TIF/TFW GIS-friendly products have been created back to the beginning of the mission: March 2014. They can be found on jsimpson server in the directories:
Documentation for the TIF/TFW products is contained in the document README.GIS.pdf in /NRTPUB/imerg/gis.
At least 156 people in Bangladesh were killed during the past week by landslides and floods caused by heavy rainfall. Monsoon rainfall has been especially heavy over this area that includes southeastern Bangladesh, northeastern India and western Burma (Myanmar). This disaster follows quickly on the heels of deadly cyclone Mora which hit the same area a couple weeks ago.
In the past couple weeks rainfall has had a significant impact on Sri Lanka, southwestern India, Bangladesh and eastern India. Monsoon rainfall caused widespread flooding, devastating mudslides and displacements of many thousands of people in Sri Lanka. Over 200 people's deaths have now been attributed to this disaster. Then cyclone Mora formed in the Bay Of Bengal on May 27, 2017. Heavy rain from Mora and it's remnants moved over southeastern Bangladesh and northeastern India. Monsoon rainfall also started to move into southern India.
