Funded by the Austrian Science Fund (FWF, ORD-68), we calculate and provide tropospheric delays and models as open access data. This server replaces ggosatm.hg.tuwien.ac.at, which will be shut down in March 2019. The portfolio of tropospheric delays and models provided here is significantly enhanced compared to the previous version. A manual on the usage and application of the troposphere products can be found in the readme.txt.
