Accurate error covariance is crucial for postprocessing gravity recovery and climate experiment (GRACE) gravity field solutions in terms of spherical harmonic coefficients (SHCs). Unfortunately, most GRACE SHC products only provide formal errors of S

High mountain Asia (HMA) holds the largest concentration of glaciers outside the polar regions, and the melting glaciers provide freshwater for more than one billion people. Therefore, it is crucial to estimate glacier mass changes over HMA. Though G
