On May-24, 2019, the GRACE-FO project released their first Level-1 data products, which are now available at NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) and GFZ’s Information System and Data Center (ISDC).

This first product release includes all Level-1 data necessary for the generation of Level-2 gravity field products. The data span the period from June 2018, initial power-up of the instruments during in orbit check out (IOC), through early May 2019, the most recent data available in the operational Phase E. Subsequent Level-1 products will be available at PO.DAAC and ISDC approximately every 7 days starting on May-30.

Corresponding Level-2 gravity field products will begin to be available starting on June-12, with the complete first mission year delivered to each data center by end of June. Subsequent Level-2 monthly gravity field products will be available at PO.DAAC and ISDC on a regular basis starting in July 2019.

Please refer to Level-1 release notes and documentation for a detailed description of the data, file formats, updates, and conventions.
