The techniques and software presented in the article are to be used for taking into account the solid precipitation (in the form of snow deposits) effect on the seasonal changes in the Earth’s gravitational field. The combined gravitational effect of the snow cover is similar in value with the gravity measurements accuracy. Special program has been developed which makes it possible to assess the snow pack effect on the gravity changes. The map presented here shows gravitational field changes due to solid precipitation.
Changes in the Earth’s global gravity field due to air displacement have been determined in the centers of equidimensional 5-degree trapezoids on the earth’s surface and relevant schematic maps have been made. Using the method of harmonic analysis and calculated data on the gravity changes, harmonic factors for changes in the gravity field dynamic component have been determined. The values of fundamental constants changes due to the air displacement have been found.
