Comparison and Analysis of Different Mascon Model Results
Abstract The Mascon data published by different research institutions are introduced briefly in this paper. Pesults of terrestial water storage variation which calculated y Mascon data, GLDAS model data and spherical harmonic coefficients method are compared in global and regional scales. The results show that Mascon data of different institutions have consistency. Signal-to-noise ratio and spatial resolution of terrestrial water storage variation results are improved by the Mascon method compared with the spherical harmonic coefficients method. More true signals of regional mass variation are kept. Time series of regional terrestrial water storage variation results which calculated by Mascon data are more relevant to GLDAS model results compared with the results of the spherical harmonic coefficients method. The signal-to-noise ratio of global surface mass variation inversion results by Mascon data are larger than results of spherical harmonic coefficients method. The JPL Mascon results are maximal.
