Access
- Python (earthaccess):
search 'GRACEFO_L3' keyword - Portal: https://podaac.jpl.nasa.gov/GRACE-FO
- Visualization tool: https://grace.jpl.nasa.gov/
Gotchas
- 300 km native resolution; don’t claim point-scale signals
- Three processing centers (JPL/CSR/GFZ) — JPL mascons are most user-friendly
- GRACE → GRACE-FO has 1-year gap
