Abstract In order to verify the feasibility of precipitable water vapor(PWV) retrieval with ground-based GPS in the way of spectrum analysis, PWV value calculated from ground-based GPS and microwave radiometer(MWR) data are studied in a long period and two short periods, based on singular spectrum analysis(SSA). The major trends and cycles can be extracted from those two kinds of data in different periods. The results show that RMSE of PWV value calculated from ground-based GPS and MWR value is about 2 mm. Between the two kinds of data, there is a strong correlation in major trends and similarity in cycles. This shows that PWV retrieval with ground-based GPS is feasible.
