NASA GRACE-FO Project
This data set is produced by the Center for Space Research (CSR) GRACE-FO (Gravity Recovery and Climate Experiment Follow-On) program and derives the terrestrial water storage anomaly given as equivalent water thickness. These monthly grids are derived from GRACE-FO time-variable gravity observations during the specified timespan, and relative to the specified time-mean reference period. This quantity represents the total terrestrial water storage anomalies from soil moisture, snow, surface wate

- Resolution docs-verified
- Monthly grids (temporal); spatial grid resolution not stated; hourly for ABPR-FO
- Update frequency docs-verified
- Yearly update for the ABPR-FO dataset at PO.DAAC; update cadence for the GRACE-FO grids is not stated
- Formats docs-verified
- ASCII · netCDF · GeoTIFF
- Access llm-inferred
- Open data under CC BY 4.0 (licence from ENTRY metadata); no authentication (auth null)
Useful for
- Use cases llm-inferred
- Regional terrestrial water storage trend context for groundwater and drought assessments · Catchment-scale storage anomaly check alongside gauge and rainfall records · Long-term water storage baseline for water resources strategy inputs
- Audience llm-inferred
- hydrologists · water resources engineers · GIS analysts · environmental consultants
Limitations
- Constraints docs-verified
- ACX2 data not available for 03/2023-06/2023, so the processing version varies over time · Post-processing filters applied to reduce correlated errors, which limits spatial detail · Level-1A, Level-1B and Level-2 products are marked for expert use only · ABPR-FO covers only Aug 2022 to Aug 2023 · Anomalies are relative to a time-mean reference period, so absolute storage is not provided
