PPS's 'ftp://gpmweb2' Service will be Replaced Soon

Due to recent changes to popular web browsers (i.e. Firefox, Edge, Chrome, etc.) PPS's gpmweb2 FTP content which was viewable with a web browser may no longer display. This content will be moving to an alternate 'HTTPS' service. Consequently, all the old links and source material referencing ftp://gpmweb2 will be updated to refer to 'https://gpmweb2https' once this service is activated for the PPS public website: https://pps.gsfc.nasa.gov These changes and the new 'HTTPS' service are expected to go into effect around or before the next PPS preventive maintenance downtime on Tuesday May 04

Accessing the PPS Near Real-time (NRT) Data using HTTPS and the jsimpsonhttps Server

Date Last Updated

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 Near Real-time (NRT) Data (jsimpson)

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. PPS determined, after reviewing available

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
