PPS Maintenance Jul 1 - Jul 8, 2021, Early July GPM Data Production will be on Hold

PPS will be performing crucial server updates, scheduled preventive maintenance and data product verification starting on Thursday July 01, 2021 through Thursday July 08, 2021 (Thu Jul 1, 8:00 AM EST - Thu Jul 08, 2021 Time TBD). During this period PPS will finish producing GPM data products for June 2021. GPM July 2021 production data will then be placed on hold while PPS upgrades our servers and then analyzes the GPM July data after the OS update . Please see the schedule below for the specific details and times. July 1 - 5, 2021: PPS will be closing out monthly processing for June 2021 GPM

PPS's 'ftp://gpmweb2' Service has Been Replaced with 'https://gpmweb2https'

PPS's new 'https://gpmweb2https' service is now accessible to the public and we have modified our website: https://pps.gsfc.nasa.gov/ All the previous links and source material referencing ftp://gpmweb2 have been or will be completely updated to refer to the new 'https://gpmweb2https' address. This effort will allow you to view documents and other content within your browser as you did before. As an example see: https://gpmweb2https.pps.eosdis.nasa.gov/pub/GPMfilespec/filespecMeta.G… PPS will also make 'gpmweb2ftps.pps.eosdis.nasa.gov' ftps service available as an alternative. You can

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

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.
