Seasonal changes of Earth's gravitational field due to solid precipitation

摘要

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.
