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.
The prospects for studying the state of troposphere on the territory of Novosibirsk region are shown. They are based on GNSS-measurements made at continuously operating reference stations. The results of tropospheric delays estimations on the local territory are presented.
