Fig. 5

Time-series of the satellite-based gravity changes at Mizusawa (39.1°N, 141.1°E) from GRACE/GRACE-FO observation with eight different filters (DDK1–8) and no filter. Open circles denote the gravity changes relative to April 2002–April 2003 time-mean, and error bars denote the observation errors. Blue lines show the results of fitting the functions given by Eq. (5) to the gravity data. Red lines show the same functions but without periodic components
