Tutorial: How to Access the new PPS FTPS Servers
Due to NASA network policies the NASA Precipitation Processing System (PPS) will be transitioning from FTP to FTPS for access to download GPM and TRMM data. As a result of this change, users may need to update the methods they use to download data. Due to these changes users will no longer be able to access the PPS FTPS servers using a web browser, and will need to connect using either the command line or dedicated file transfer software.
One piece of software that can be used to connect to the new FTPS servers is Filezilla, which is free and open source, and is available on Mac, Windows, and Linux operative systems. Filezilla can be downloaded here: https://filezilla-project.org/
NASA does not explicitly endorse the use of any particular piece of software and cannot provide detailed technical support for this software, but these instructions are provided in case they are useful to the end user.
- Open Filezilla
- Go to "File" -> "Site Manager"
- Click on "New Site" to set up a new connection to the PPS FTP server.
- In the text box enter the name you would like to call this saved connection (i.e. "Jsimpson FTPS")
- Leave "Protocol" set to the default ("FTP - File Transfer Protocol")
- In "Host", enter "jsimpsonftps.pps.eosdis.nasa.gov"
- Leave "Port" set to blank
- In "Encryption" set to "Use explicit TLS over FTP if available"
- Leave "Logon Type" set to "Normal"
- In both the "User" and "Password" fields, enter the email address that you have registered with the PPS. If you have not yet registered with the PPS, please do so here: https://registration.pps.eosdis.nasa.gov/registration/
- Click "Connect" to connect to the server. You can then use this bookmark you have created in future sessions by going to "Site Manager", clicking on the site, and clicking "Connect"
