Fig. 4From: Mass-related excitation of polar motion: an assessment of the new RL06 GRACE gravity field modelsComparison of the equatorial effective angular momentum functions \(\chi _1^{{\rm mass}}\) and \(\chi _2^{{\rm mass}}\) computed from CSR RL05 (blue) and CSR RL06 (red) (mean values of the time series are removed). The corresponding correlation coefficients and relative standard deviations (RSD) are providedBack to article page
