PO.DAAC FTP RETIREMENT: Important Information for Users

Wednesday, November 14, 2018

PO.DAAC is reaching out to you to follow up on your effort to utilize PO.DAAC Drive for browsing and retrieving data at PO.DAAC.  Our goal is to reduce the operational impact to our users that are transitioning away from anonymous FTP, and also provide a higher level of operational support and service.  

Earlier this year, we informed our users (https://podaac.jpl.nasa.gov/announcements/2018-06-05_Deprecation_of_FTP_at_PO.DAAC) that NASA was in the process of deprecating the use of the FTP protocol for data and information access, and that PO.DAAC was offering PO.DAAC Drive as a robust FTP alternative for browsing and retrieving data at PO.DAAC. 

While FTP is a convenient data access mechanism, HTTPS transfers are designed to increase download performance and improve security during data retrieval. HTTPS based data retrievals offer comparable functionality to FTP and allow a client to maintain a single connection to a server that can be used for any number of simultaneous file extractions. 

PO.DAAC Drive (https://podaac-tools.jpl.nasa.gov/drive/) offers file navigation and download through an interface served directly through your browser, and with a familiar look and feel.  It also allows users to access data via a command line so that interactions can be easily scripted.  

Please note that each user must create a NASA Earthdata Login Profile in order to download files. Instructions to register for an Earthdata Login account are available at https://urs.earthdata.nasa.gov/users/new

After 3 June 2019, FTP service will no longer be available at PO.DAAC. We recommend an earlier transition to maximize familiarity with PO.DAAC’s operational HTTPS data distribution services and minimize data disruption when FTP service is no longer available. To ensure a successful transition for all FTP users, our User Services Team is standing by to address all technical issues and concerns.

To view the NASA Earthdata webinar entitled "Goodbye FTP, New Ways to Access NASA's Physical Oceanography Data at PO.DAAC" please see: https://youtu.be/kd8yjl6YiH8

This webinar provides a demonstration of how to use Drive, and how to discover and extract data using other services such as PO.DAAC Web Services.

Please let us know if there is anything we can do to help in the process.
