IMERG Rainfall Totals from Medicane Ianos
From September 14th - 20th, 2020, NASA’s IMERG algorithm estimated the rainfall from a Mediterranean cyclone with tropical-like characteristics, commonly known as a “Medicane”, which flooded parts of Greece. Medicanes typically appear once or twice a year and are similar to tropical storms in that both have a symmetric structure, a warm core, a clearly visible eye, and winds of at least tropical-storm strength. This particular storm system, dubbed "Ianos" by the National Observatory of Athens, led to media reports of flooding throughout the islands of Kefalonia and Zakynthos off the western
IMERG totals from hurricane sally
The northern Gulf Coast has seen its share of storms this busy hurricane season. At the end of August, then Tropical Storm Marco brought heavy rains to parts of the Florida Panhandle while western Louisiana took a direct hit from the much more powerful Category 4 Hurricane Laura. Now, just over 3 weeks since Laura made landfall, the northern Gulf Coast was struck again, this time by Hurricane Sally. Though not as powerful as Laura, the still rather strong Sally behaved more like Marco. But, while Marco was largely sheared apart with most of the rain well northeast of the center as it slowed

PPS Extended Maintenance and Archive Downtime Sep 22 - Sep 24, 2020 (3 Days)

The PPS (Precipitation Processing System) will be down starting Tuesday September 22, 2020 (0800 EDT|1200 UTC) -through- Thursday September 24, 2020 (Uptime- Still TBD) for a very important multi-day archive upgrade. It is not anticipated that this work will have any impact on the near real-time data servers (jsimpson) or data collection from the GPM satellite and constellation. It is important to be aware that this will be an extensive PPS GPM Archive upgrade that will impact crucial PPS services. Services that may NOT be available during this time include: PPS 'arthurhou' GPM research data

PPS Will be Down for Special Maintenance on Sunday Sep. 13, 2020

The PPS (Precipitation Processing System) will be down Sunday September 13, 2020 from approximately 1:00 PM - 7:00pm EDT (17:00 - 23:00 UTC) for scheduled GPM archive maintenance. It is projected that PPS's GPM research data server (Arthurhou) will offline for 6-8 hours and all data processing, etc. will be halted until maintenance has concluded. Data will continue to be collected from the GPM Core Observatory and constellation satellites, and access to the GPM near real-time data server (Jsimpson) will not be affected. During this time all data transfers between PPS source and its consumer
Maps showing the Average Precipitation Rate in Lake Victoria, Africa - Day vs. Night
Lake Victoria is the largest lake in Africa and an economic and food security lifeline for roughly 30 million people living near its shores in Uganda, Kenya, and Tanzania. But it also takes lives. Cyclical, daily weather patterns around the lake create violent nighttime thunderstorms that kill roughly 3,000 to 5,000 fishermen per year. “This is definitely one of the stormiest places on Earth,” said Wim Thiery, a climate scientist at the Vrije Universiteit Brussel who has studied Lake Victoria for several years. “Almost every night, you see these intense thunderstorms and sometimes even water
