Summary:
The zenith total delay (ZTD) obtained during the positioning process in GNSS varies due to the amount of water vapor in the atmosphere. Although the ztd can be considered as a potential possibility of rainfall, variation of ztd results in false alarm frequently. In this paper, differential time series of ztd is newly introduced to rainfall nowcast in order to improve accuracy. Observation data for five months are postprocessed using precise point positioning algorithm, then false alarm rate is experimentally investigated.
