Description
The tropospheric parameters product includes total and wet zenith path delays and the meteorological data for IVS stations. The product is available in a series of weekly files with tropospheric results derived from all IVS-R1 and IVS-R4 sessions (submission directory). The station-wise files are stored in weekly directories following the GPS week numbers. Long-term files are stored in the directory long-term which, in turn, is subdivided into folders for the contributing analysis centers. The operational product is available on the IVS Data Centers one month after availability of each new session data base. The tropospheric parameters product includes total and wet zenith path delays and the meteorological data for IVS stations participating in the weekly IVS-R1 and IVS-R4 sessions. The results are available in a series of weekly files with combined tropospheric estimates derived from all IVS-R1 and IVS-R4 sessions since January 2002. Until June 2003 the files were created in the IVS Pilot Project phase, whereas starting with July 2003 the combined tropospheric estimates are regular IVS products. The combined troposphere products are produced at the GFZ Potsdam troposphere combination center.
