چکیده
This paper comprehensively analyzes the effect of surface mass loading on GPS height time series in terms weighted root mean square (WRMS), annual timescale, velocity and noise properties. Considering complexity hydrological process, we adopt same atmospheric nontidal ocean estimated from TUGO-m barotropic model (ATMMO) different loadings Global Land Data Assimilation System (GLDAS) Surface Discharge Model (LSDM). The results indicate that combined ATMMO & GLDAS outperforms LSDM reducing WRMS times due to phase asynchrony between LSDM. Furthermore, cross-wavelet transform-based (XWT-based) semblance analysis is adopted quantitatively express relationship combinations. show (1) main driving force for fluctuation height, (2) term better matches than Consequently, it concluded may not work well Eurasia with its current accuracy. Finally, investigate impacts correction site For most sites, change can reach 0.1 mm/year after correction, indicating influence should be ignored construction millimeter-level earth reference frames. However, some uncertainty increased undesirable changes properties, suggesting using correct potentially feasible but sufficient.

Estimates of Minor Ocean Tide Loading Displacement and Its Impact on Continuous GPS Coordinate Time Series
The site displacement due to ocean tidal loading is regarded as one of the largest uncertainties in precise geodetic positioning measurements, among which the effect of minor ocean tides (MOT), except for the 11 main tidal constituents, are sometimes neglected in routine precise global positioning system (GPS) data processing. We find that MOT can cause large vertical loading displacements with...
متن کاملSeasonal Hydrological Loading in Southern Tibet Detected by Joint Analysis of GPS and GRACE
In southern Tibet, ongoing vertical and horizontal motions due to the collision between India and Eurasia are monitored by large numbers of global positioning system (GPS) continuous and campaign sites installed in the past decade. Displacements measured by GPS usually include tectonic deformation as well as non-tectonic, time-dependent signals. To estimate the regional long-term tectonic defor...
متن کاملComparative Study Among Different Time Series Models for Monthly Rainfall Forecasting in Shiraz Synoptic Station, Iran
In this research, monthly rainfall of Shiraz synoptic station from March 1971 to February 2016 was studied using different time series models by ITSM Software. Results showed that the ARMA (1,12) model based on Hannan-Rissanen method was the best model which fitted to the data. Then, to assess the verification and accuracy of the model, the monthly rainfall for 60 months (from March 2011 to Feb...
متن کاملImpact of solid Earth tide models on GPS coordinate and tropospheric time series
[1] Unmodelled sub-daily periodic signals can propagate into time series of daily geodetic coordinates and tropospheric estimates at various different frequencies. Geophysical interpretations of geodetic products, particularly at seasonal timescales, can therefore be affected by poorly modelled signals in the geodetic analysis. In this study, we use two solid Earth tidemodels (IERS2003 and IERS...
