Gravity change associated with hydrological effect. a An orange line indicates the snow water equivalent (SWE) value observed at Long Lake’s weather station (green triangle in Fig. 1), and a cyan line indicates the SWE value at the EGAN’s gravity point obtained from the GLDAS-2.1 data-set (Rodell et al. 2004). b Monthly gravity change at EGAN, calculated from the GLDAS-2.1 model (Rodell et al. 2004). Colored lines in the top, middle, and bottom of the panel indicate the calculated gravity changes associated with mass variations in soil moisture, snow and canopy, respectively. Pink and green lines indicate the gravity changes due to the elastic loading deformation and mass attraction (\(g_e\) and \(g_a\)), respectively, and cyan lines indicate the sum of the two effects (\(g_e + g_a\)). c Cyan lines indicate the hydrological gravity changes at six AG points in SE-AK, calculated as the sum of the loading/attraction effects due to soil moisture, snow and canopy (see the panel b). In each panel, the circles indicate the values at the time when the AG values were measured in SE-AK
