Fig. 13From: Troposphere delay modeling in SLR based on PMF, VMF3o, and meteorological dataTime series of differences in geocenter coordinates for solutions with different approaches of ZTD modeling (Top) w.r.t. the M–P solution. The solid line represents the Savitzky–Golay filter with 11 weeks of windowing. The bottom figure describes the periodogram of geocenter coordinates for the X, Y, and Z componentsBack to article page
