Click the map or a well (●). Storage series are changes since Jan 2016 (mm of water). Model D: fine-tuned, with GRACE; Polygon B uses track 27 only.
No point selected.

Observed vertical motion (model input, mm)

Model D inversion (mm water; compaction in mm)

W3RA layers (mm water, 0.1° cell)

GLDAS-2.2 layers (mm water, 0.25° cell; to 2024-01)

GRACE/GRACE-FO total water storage (mm, mascon grid cell)

Nearest well: water level (m, up +)

GLDAS-2.2 assimilates GRACE, so it is not independent of GRACE. W3RA contains no irrigation pumping. GRACE mascons are ~300 km wide. Well depths are unknown.
