The PO.DAAC is pleased to announce that the complete historical data records of GRACE Level 2 Release 06 (RL06) datasets are available. The complete records include all available historical data from April 2002 to June 2017. The initial publications for the RL06 datasets were released on 07/16/2018 (CSR/JPL) and 08/20/2018 (GFZ) respectively; please refer to those earlier announcements for more details on how to access those respective datasets.

If you have any questions about the datasets, please contact the PO.DAAC at or visit the PO.DAAC Forum.

Important Information for Users:

NASA is in the process of deprecating the use of the FTP protocol for data and information access. PO.DAAC is pleased to offer PO.DAAC Drive as a robust FTP alternative for browsing and retrieving data at PO.DAAC ( It 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. The entire PO.DAAC archive can also be mounted to a local computer as a virtual data store.

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.
