Map of the multi-year velocities

The EPN Densification station velocities result from the multi-year combination of all available national long term GNSS processing results. The combination is regularly updated, the current version is D1933. The velocities are expressed in ETRF2000 and based on the solution computed in ITRF2014 and the reference epoch is 2010.

Horizontal Velocities
ETRF2000 horizontal velocity field derived from the latest EPN Densification cumulative solution. In ETRF2000, the horizontal velocities are expressed with respect to the Eurasian plate. The Eurasian plate rotation model from ITRF2014 (Altamimi et al., 2017) has been used. The green dots on the map indicate the sites with less than 3 years of observations, which have unrealistic velocities, therefore not plotted on the map.
Vertical Velocities
The ETRF2000 vertical velocity solution derived from the latest EPN Densification cumulative solution. The uplift is indicated red, subsidence with blue arrows. The green dots on the map indicate the sites with less than 3 years of observations, which have unrealistic velocities, therefore not plotted on the map.
