The PO.DAAC is pleased to announce the public release of the GRACE-FO Level-3 Monthly LAND/OCEAN Mass anomaly RL06.2 v04 datasets from the Center for Space Research (CSR).
This CSR GRACE-FO RL06.2 data is an updated version of the RL06.1 (DOI: 10.5067/GFOCN-3C614 and 10.5067/GFLND-3C614) Level-3 data products with the inputs of RL06.2 L2 data. RL06.2 differs from RL06.1 only in the handling of onboard GPS data set during Level-2 processing. GPS handling for RL06.2 was re-assessed due to steady degradation in low degrees of the spherical harmonic solutions during late 2022 and 2023 in RL06.1. The resulting RL06.2 time series shows improvement in the low degree spherical harmonic coefficients after 2022. The datasets will be updated monthly given no data or operation interruption.
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. Several examples are provided on the dataset landing page.
