One of the major sources of uncertainty affecting vertical land motion (VLM) estimations are
discontinuities and trend changes. Trend changes are most commonly caused by seismic …

In space geodetic data analysis, improving tropospheric delay modelling is motivated by the
correlation between tropospheric zenith total delay (ZTD) and the station height. The …
