GFZ GRACE Level-2 RL06 datasets release

Monday, August 20, 2018

The PO.DAAC is pleased to announce the public release of the GRACE Level-2 Release 06 (RL06) datasets from the German Research Centre for Geosciences (GFZ).  These datasets complete the release of GRACE Level-2 RL06 products (see Release announcement on July, 16, 2018).  The RL06 version of GRACE Level-2 has made several significant improvements and updates from the current RL05, including updated background force models and improved parameterizations. For more details, please read the following online documents: “GFZ Level-2 Processing Standards Document for Product Release 06 GRACE” and “GFZ Level-2 GRACE Products - Release Notes Version 6.0”. This release includes five Level-2 products from GFZ: GAA, GAB, GAC, GAD, and GSR, which are all in compressed ASCII format and can be accessed through both FTP and Drive. The GRACE RL06 datasets have been redesigned with a new header structure, which complies with the PO.DAAC standard metadata model and is formatted in human-readable YAML format.  This header and the new Level-2 file naming convention will also be used for GRACE-FO data.

In addition, the GRACE Level-1B RL03 dataset is also being released.  This dataset consists only of reprocessed Star Camera and K-Band Range Level-1B products and was used, along with the other Level-1B RL02 data, to produce GRACE Level-2 RL06.
