Continuous GPS Time Series Analysis

South Pacific Sea Level Climate Monitoring Program (SPSLCMP)

The plots in the time series graphs show the east, north and up components for each station position determined from the weekly GPS solution.

  Summary: This combined SPSLCMP GPS solution has been aligned to International Terrestrial Reference Frame 2000 (ITRF2000) using the latest available International GPS Service (IGS) combined cumulative solution. Error bars are 1 sigma. All variance-covariance has been re-scaled to better reflect actual precision. Each solution ’circle’ represents a weekly combined solution. Outliers are not shown on plots. It is important to note that the length of the time series is too short for reliable vertical station velocity estimation. As the data collection and the height time series becomes longer, and the strategy of simultaneous estimation of velocities and periodical or seasonal signals is used, the estimates of the vertical crustal motion will become more accurate and reliable.
