Document Description

At the end of 2020, PPS anticipates that it will replace the current FTP access to its Production data archive with FTPS and HTTPS access. In choosing between FTPS and HTTPS, select HTTPS in situations where firewall restrictions prevent FTPS access.

Precipitation Processing System (PPS) Transition from FTP to FTPS for GPM Research / Production Data (arthurhou)

Date Last Updated
January 15th, 2021
Document Description

NASA information security management authorities mandated that continued use of the File Transfer Protocol (FTP) should not be allowed, even when used to provide access to publicly-available, non-sensitive information. This decision was made because FTP login credentials are sent in clear text. For this reason, they mandated that all FTP sites either convert to some form of encrypted login mechanism or be shut down.

Final Reminder: FTP Access on PPS's 'arthurhou' Production Server, will End On January 19, 2021

This is the final reminder that starting on Tuesday January 19, 2021, PPS will transition from FTP access to FTPS access (main method) and HTTPS access (secondary method) for data transfer from the PPS's 'arthurhou' GPM Production data server Elimination of the less secure 'ftp' protocol is mandated by NASA/ GSFC security policy. This change will require PPS data users to retrieve data using alternative methods and tools. Please note that 'arthurhou' already supports FTPS and HTTPS data transfers. Details of how to access PPS FTPS and HTTPS services can be found at the links below: Click here

Temporary delay of GPM NRT Data on December 7, 2020

The Precipitation Processing System is planning to migrate the jsimpson.pps.eosdis.nasa.gov (which includes jsimpsonftps.pps.eosdis.nasa.gov) to the CentOS 8 operating system. This update will mean that GPM near real-time (NRT) data will not be available to users during the period of the update. The action is planned for Monday, 7 December 2020. We intend starting at 14 UTC (09:00 EST). We hope the outage will be between 3-5 hours. During this period no GPM NRT will be available. Some data will not be produced at the usual time during this period and will be behind normal latency. No data will

IMERG Total from Cyclone Gati
Wednesday, November 25, 2020
On November 22, 2020, Cyclone Gati became the strongest storm to hit Somalia since satellite records began five decades ago. Gati made landfall with maximum sustained winds of 170 kilometers (105 miles) per hour, a category 2 storm on the Saffir-Simpson scale. The storm brought more than a year’s worth of rain to the region in two days. Local authorities report at least eight people were killed and thousands have been displaced. The map above shows rainfall accumulation from November 21-23, 2020. These data are remotely-sensed estimates that come from the Integrated Multi-Satellite Retrievals
