Funded by the Austrian Science Fund (FWF, ORD-68), we calculate tropospheric products and provide them as open access data. The portfolio of tropospheric products comprises delay models for several space geodetic techniques, direct ray-traced delays for VLBI observations, atmospheric pressure loading data, as well as many auxiliary tools.
A manual on the usage and application of the troposphere products can be found in the readme.txt.

Structure of the troposphere delay models

The following two organigrams give an overview of the structure of the troposphere products.

VMF3 data at Wettzell (Germany)

This plot shows a comparison of VMF3 operational data (VMF3OP, blue) with VMF3 forecast data (VMF3FC, red) for the Geodetic Observatory Wettzell in Germany over the last 4 weeks. The red line is always two days ahead of the blue line, since VMF3OP is always published for the previous day and VMF3FC for the upcoming day.
