The PO.DAAC is pleased to announce the public release of the GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics RL06.2 dataset from the Center for Space Research (CSR).

This CSR GRACE-FO RL06.2 data is an updated version of the initial GRACE-FO RL06 (DOI: 10.5067/GFL20-MC060) and RL06.1 (DOI: 10.5067/GFL20-MC061) Level-2 data products. RL06.2 differs from RL06.1 only in the handling of GPS data set during Level-2 processing. GPS handling for RL06.2 was re-assessed due to steady degradation in low degrees during late 2022 and 2023 in RL06.1. The resulting RL06.2 time series shows improvement in the low degree coefficients after 2022. In addition, the RL06.2 datasets are published directly in the NASA Earthdata Cloud with all files uncompressed. Similar to RL06.1, all the three files are formatted in ASCII with YAML encoding header, in compliance with ACDD-1.3 and CF-1.7 metadata conventions. They are active forward stream data files, and will be updated monthly, or when the new data are appended by the data processing centers.

The dataset is described and discoverable via the PO.DAAC dataset information page. Users are encouraged to use the PO.DAAC data downloader and subscriber to download the data.
