Description

Seasonal components in the ZTD (Zenith Tropospheric Delay) and IWV (Integrated Water Vapour) time series are important and provide information about weather conditions in a given region. The main purpose of this research is to analyze linear trends and seasonal components of ZTD’s and IWS’s in GPS reprocessing campaign at selected stations in Europe (IGS repro1 dataset-URL1). The seasonal components and linear trends were estimated using the LSE (Least Square Estimation) approach. The frequencies in the ZTD and IWV time series were found and periodograms were prepared. The frequency spectrum was estimated by using combined sine and cosine functions to the time series.
