Description
Integrated water vapour (IWV) is calculated from processing of GNSS data and IWV time series are produced. IWV time series analysis is important to monitoring of climate changes. Inhomogeneities caused by earthquakes, changes in hardware or equipment etc., can affect actual trends and seasonal variability in time series.
This work presents a methodology for change point detection and series homogenization IWV estimates at various IGS stations in the period 1995-2010 from IGS-Repro1 datasets. Mann-Kendall test, Mann-Kendall Rank Correlation test, von Neuman Ratio test, Pettitt-test and Linear Regression were applied. The aim is to detect significant inhomogeneities occuring in different IGS stations and investigate the reasons of inhomogenities.
