- Abstract
We calculate the traditional atmospheric lcx1d correction according to the global atmospheric pressure model, but the medium-wave and long-wave signal is dominant in the global atmospheric pressure model, and the short-wave signal, which highlights the regional characteristic information is lacking. The shortwave signal in the spatial information cannot be ignored when studying the influence of high precision regional atmospheric load. Based on the theory of the earth gravity field, we introduce the removal-recovery method, and combine the global atmospheric pressure data provided by ECMWF and the regional high precision atmospheric pressure data CLDAS-V2. 0. Based on the load spherical harmonic coefficient and the regional load Green's function method, we obtain the load effect of atmospheric pressure change in western Yunnan. The results show improvement in both the spatial and temporal resolution of the atmospheric load deformation field. The influence of regional atmospheric pressure load calculated by removal- recovery method can provide reference for solid earth deformation and CORS station time series analysis.
