Distances between selected PS points from ascending and descending tracks and the GNSS station. PS targets were ordered from the longest distance (334.28 m) from the WLAD station, and the shortest distance (0.98 m) from the IJMU station.

The main aim of the article was to analyse the actual accuracy of determining the vertical movements of the Earth’s crust (VMEC) based on time series made of four measurement techniques: satellite altimetry (SA), tide gauges (TG), fixed GNSS stations and radar interferometry. A relatively new issue is the use of the persistent scatterer InSAR (PSIn...

... areas without infrastructure, rock outcrops, hard unvegetated earth surfaces and boulders can be used as PS points. However, the locations of PS points and GNSS stations do not coincide; the distances between selected PS points and the GNSS station are shown in Figure 10. The longest distance (of more than 300 m) was noted with the WLAD station, which is located on port breakwaters. ...

The Coherent Pixels Technique Interferometry Synthetic Aperture Radar (CPT-InSAR) method of inverting surface deformation parameters by using high-quality measuring points possesses the flaw inducing sparse measuring points in non-urban areas. In this paper, we propose the Adaptive Coherent Distributed Pixel InSAR (ACDP-InSAR) method, which is an a...

... The InSAR-based ground motion service uses active corner reflectors -transponders -as a central unit of the new method. In such a way, we can tie InSAR motions with velocities from GNSS if the transponders are located in the vicinity of the GNSS station or TG [24]. In summary, with a sufficiently long-time span reaching from 5 to 12 years, we were able to obtain reliable estimates for the vertical ground motion at the TG sites along the Adriatic Sea coasts. ...

Tide gauge observations provide sea level relative to the Earth’s crust, while satellite altimetry measures sea level variations relative to the centre of the Earth’s mass. Local vertical land motion can be a significant contribution to the measured sea level change.Satellite altimetry was traditionally used to study the open ocean, but this technology is now being used over inland seas too.The difference of both observations can be used to estimate vertical crustal movement velocities along the sea coast. In this paper, vertical crustal movement velocities were investigated at tide gauge sites along the Adriatic Sea coast by analyzing differences between Tide Gauge (TG) and Satellite Altimetry (SA) observations. Furthermore, the estimated vertical motion rates were compared with those from nearby GNSS measurements.The study determines the practical relationships between these vertical crustal movements and those determined from unrelated data acquired from the neighbouring GNSS stations. The results show general consistence with the present geodynamics in the Adriatic Sea coastal zone.
