| Abstract: | Comparison of PWVs from collocated ground GPS stations and COSMIC observations confirms their consistency which indicates the possibility to combine data from these two techniques,Statistical analysis of COSMIC occultation events during January and February 2010 is done.The combination of data from currently available IGS GPS stations and COSMIC occultation events for deriving regional PWV map is conducted and the results are assessed.An internet-based PWV service system is designed for providing both ground-and space-based PWVs and also for receiving GPS ground station data from users in order to improve the regional PWV information of their interest. |
