| Summary: | <!--!introduction!--> The masses in the Earth’s atmosphere and surface cause the crust to deform. Part of these mass movements are periodic, e.g. tides in the oceans and in the atmosphere, but there are also non-periodic movements. Periodic (tidal) phenomena are quite well understood and modelled, whereas the non-periodic (non-tidal) phenomena are harder to model due to non-repeating patterns in the mass changes. Understanding the tidal and non-tidal loading improves the quality of the geodetic time series and thus, improves the stability of the reference frames. The tidal corrections to geodetic time series are done routinely, following recommendations and guidelines of the IERS Conventions. We investigated the 3D deformations in Fennoscandia induced by non-tidal atmospheric loading (NTAL) through GNSS time series modeling using GAMIT/GLOBK software. We have used 5 months of data from continuous GNSS stations belonging to FinnRef (Finnish Permanent GNSS Network) and EPN (EUREF Permanent GNSS Network) ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
