Physical heights were traditionally determined without considering the dynamic processes of
the Earth induced from temporal mass variations. The Gravity Recovery and Climate …

Temporal variations of hydrological mass cause changes in geoid height and surface
deformation, resulting in time variation of orthometric height. The daily gravity recovery and …

We describe the development of a hybrid geoid model for Peninsular Malaysia, based on
two approaches. The first approach is utilising an ordinary method fitting the gravimetric …

Almost half of the Earth's land is covered by large river basins. Temporal variations of
hydrological masses induce time-varying gravitational potential and temporal mass loading …

With climatic changes, access to freshwater resources becomes more limited.
Correspondingly, water monitoring methods in sensitive or critical areas in terms of …

The objective of this research is to assess temporal variations of orthometric/normal height
(Δ H/Δ H*) at proposed International Height Reference Frame (IHRF) sites. GRACE/GRACE …

Tide gauge observations are samples of geodetic time series realized depending on the
time. These observations like other experimental time series might have trends, short gaps …

The results obtained through GRACE/GRACE Follow-On spherical harmonic coefficient
model exhibit noticeable north–south strip noise. While applying low-pass filtering along the …

Physical height changes play an important role in the modernization of national/international
levelling networks in the discipline of geodesy. This paper represents a software package …

Since 2018 the main geodetic activities at the national level in Poland concentrated on
maintenance horizontal, vertical, gravity and geomagnetic control, continuing operational …
