Fig. 2: Datasets used for groundwater storage anomaly calculation and GRACE/FO data evaluation in the Central Valley.

a GRACE/FO observed monthly total water storage (TWS) anomalies. Red arrow indicates the driest winter in TWS for the past two decades at the begining of 2021. b Three water balance fluxes of precipitation (P), evapotranspiration (ET), and streamflow (Q). c Comparison of monthly change in TWS (dS/dt) between that derived from GRACE/FO and from an observed water balance. d Anomalies of three TWS components of soil moisture (SM), surface water (SW), and snow water equivalent (SWE). All variables are represented in equivalent water height in millimeters for the study region.
