Movie generated on 2018-09-05 using 163 GRACE spherical harmonic solutions from the University of Texas, Center for Space Research (CSR). Data is corrected for glacial isostatic adjustment (GIA) using coefficients from Ivins et al. (2013), corrected for pole tide drift following Wahr et al. (2015), smoothed using a 400km radius Gaussian filter (Wahr et al., 1998) and filtered for seasonal effects (Velicogna, 2009).
