Subregional‐scale groundwater depletion detected by GRACE for both shallow and deep aquifers in North China Plain
This study explores the capability of Gravity Recovery and Climate Experiment (GRACE) to
detect heterogeneous groundwater storage (GWS) variations in two subregions of the North
China Plain: the Piedmont Plain (PP,~ 54,000 km2, mainly exploiting shallow groundwater)
and East Central Plain (ECP,~ 86,000 km2, mainly exploiting deep groundwater). Results
show that the GWS anomalies estimated from GRACE data (2003–2013) agree well with
those estimated from in situ observations (2005–2010) for both PP (R2= 0.91) and ECP …
