Abstract 

The research analyses the impact of non-tidal atmospheric loading (NTAL) on the GNSS stations of Geoterrace network (Ukraine) and Dnister hydro power plant (HPP) in December 2019. Based on the data of 32 stations in the Western region of Ukraine authors divide them into two groups. One of the groups shows two times fewer dynamics of vertical subsidence comparing with vertical displacements due to NTAL models. The analysis of modeled NTAL with dense GNSS network of Dnister HPP-1 is also provided. The time series of up, east, north position changes of GNSS stations and NTAL models does not fully correlate. It leads us to the need for the regionalization of NTAL models and the need to calculate special corrections for engineering facilities.
