Progress in Terrestrial Water Storage Research Based on GNSS Observation
The method of inversion of terrestrial water storage using GNSS observation based on mass-loading theory is introduced,and the progress,application and development trend of using GNSS to study terrestrial water storage,as well as the joint research of GNSS with GRACE and hydrological models are described.With the continuous im-provement in the accuracy of GNSS observation and the rapid development of observational network,remarkable advances have been made in the study of terrestrial water storage by GNSS observation,and GNSS has become an important means of terrestrial water storage monitoring,and the use of GNSS to study terrestrial water storage in Chinese mainland has great potential and prospect.But it still needs to be further researched in the aspects of fine i-dentification of time series signals,optimization of inversion algorithms,and fusion of multi-source data.
