Triangular plots showing the absolute values of the estimated gravity coefficients with respect to the coefficients derived from the monthly CSR mascons (up to degree and order 180). Left panels: K/Ka‐band ranging (KBR) solutions from Gravity Recovery and Climate Experiment. Center panels: KBR solutions from GRACE Follow‐On Mission. Right panels: laser ranging interferometer solutions. The top panels show relatively good months, while the bottom panels show months with degradation in the quality of the solutions.
