Land Subsidence Estimation With Tide Gauge and Satellite Radar Altimetry Measurements Along the Texas Gulf Coast, USA
نویسندگان
چکیده
A double difference (DD) method was employed to estimate vertical land motion (VLM) at 26 tide gauge (TG) sites with record lengths of least ten years across the Texas Gulf Coast, USA, between 1993 and 2020. In method, first conducted by coupling nearby correlated TG stations remove sea-level variability for both satellite radar altimetry (SRA) data. Upon completion difference, a second performed subtracting SRA Results obtained from DD were compared against that of: 1) single (SD) through subtraction measurements SRA, 2) global navigation system (GNSS) precise point positioning (PPP) method. showed improved performance VLM estimation an uncertainty below 1.0 mm/yr most stations. Meanwhile, estimated trends acquired better ground-truth GNSS PPP solutions than SD The possesses great potential discover knowledge, particularly along coastal regions where other techniques such as interferometric synthetic aperture (InSAR) are impaired capability.

Sea Level Changes Along Global Coasts from Satellite Altimetry, GPS and Tide Gauge
The average global sea level was rising through the 20th century as a result of global warming [8, 9, 26]. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) estimated that between 1901 and 2010, the mean sea level rate 1.7±0.2 mm/yr and increased to 3.2±0.4 mm/yr between 1993 and 2010, and projected that in 2100 the largest increase in global average sea level ...
متن کاملTime-varying land subsidence detected by radar altimetry: California, Taiwan and north China
Contemporary applications of radar altimetry include sea-level rise, ocean circulation, marine gravity, and icesheet elevation change. Unlike InSAR and GNSS, which are widely used to map surface deformation, altimetry is neither reliant on highly temporally-correlated ground features nor as limited by the available spatial coverage, and can provide long-term temporal subsidence monitoring capab...
متن کاملA Survey of ICESat Coastal Altimetry Applications: Continental Coast, Open Ocean Island, and Inland River
ICESat satellite laser altimetry provides an unprecedented set of global elevation measurements of the Earth, yielding great detail over ice, land and ocean surfaces. Coastal regions in particular, including seamless land-water transitions, benefit from the small footprint (50 to 90 m), high resolution (40 Hz, ~170 m along-track), and high precision (2 to 3 cm) of ICESat. We discuss the perform...
متن کاملVertical Motion determined using Satellite Altimetry and tide Gauges
A robust method to estimate vertical crustal motions by combining geocentric sea level measurements from decadal (1992 2003) TOPEX/POSEIDON satellite altimetry and long-term (> 40 years) relative sea level records from tide gauges using a novel Gauss-Markov stochastic adjustment model is presented. These results represent an improvement over a prior study (Kuo et al. 2004) in Fennoscandia, wher...
