Noise and Velocity Field Analysis of Shanxi CMONOC Coordinate Time Series
Abstract We use Hector software to calculate the observation data of 10 continuous stations of CMONOC of Shanxi province from 2010-11 to 2021-01. We obtain the coordinate time series of the continuous stations, and determine the optimal noise model and the corrected velocity field. The results show that: white noise (WN), flicker noise (FN) and power-law noise (PL) mainly exist in the Shanxi coordinate time series data; the optimal noise model in the North direction is WN+PL; the optimal noise model in the east and up directions are WN+FN. Taking into account the influence of colored noise, the average moving speed in the horizontal direction of CMONOC in Shanxi based on the ITRF2014 framework is 33.542 mm/a, and the moving direction is SEE 26°22′12″. The average movement speed in the vertical direction is 2.214 mm/a, showing an uplift trend.
