“…[20][21][22] ). However, the required networks are sparse in many regions of the world, and GNSS time series for individual stations include many non-loading signals and technique-related errors which are difficult to separate [23][24][25] . (4) Data from other sources such as satellite laser ranging (SLR) or from the European Space Agency (ESA) Swarm 3-satellite formation are used to reconstruct low-degree models of the gravity field [26][27][28] .…”

“…The impact of neglecting the ocean loading component may be intensified in the semi-enclosed bay regions, e.g., the Gulf of Thailand, where the ocean bottom pressure effect is significant [58,63]. Note that this study obtains the atmosphere and ocean signals from the AOD product consistent with GRACE Level-2 processing while using different de-aliasing products or geophysical models, e.g., [64], which may have a different impact on the ∆r estimate. The performance comparison is beyond the scope of this study but can be considered in future analyses.…”

“…Deformation of the sea floor and surface displacements of the adjacent lands up to several centimeters result from the elastic response of the Earth's crust to ocean tides (tidal loading) [12]. The ocean is also responsible for the so-called non-tidal ocean loading [13][14][15]. These changes of the ocean bottom pressure are due to different processes-namely, the internal mass redistribution of the ocean driven by atmospheric circulation, the global water cycle, and a change in the integrated atmospheric mass over the ocean areas [14].…”

“…During the past two decades at least, many studies have been published describing the seasonal variability of the GPS-estimated heights in response to the force exerted by different types of environmental loads. Among others, recent contributions include the following [11,[15][16][17][18]. Long-term signals due to different natural and anthropogenic processes may also characterize the GPS height time series [1,19].…”
