The PO.DAAC is pleased to announce the public release of the GRACE/GRACE-FO Level-4 Monthly Global Ocean Mass Anomaly v1.0 dataset funded by the NASA Heat and Ocean Mass from Gravity ESDR (HOMaGE) project.

This release contains the time series of the averaged monthly Global Ocean Mass Anomalies (GOMA), which are derived from the measurements of the GRACE and GRACE Follow-On (G/GFO) satellite missions. Three GOMA data fields are provided based on the spherical harmonic gravity fields from three G/GFO SDS centers: JPL, CSR, GFZ. The time series file is in netCDF format, and in compliance with ACDD-1.3 and CF-1.7 metadata conventions, covering the temporal range from 04/2022 to present, and will be updated bi-monthly.

The dataset is described and discoverable via the PO.DAAC dataset information page. Users are encouraged to use the PO.DAAC Data Downloader/Subscriber ( to download the data.
