AB: The paper uses homogeneously reprocessed VLBI (OCCAM6.1e, at DGFI) and GPS (Bernese, at GFZ) long-term position time series to determine atmospheric loading coefficients. As the VLBI and GPS data analysis is done using fully homogenized models (for troposphere etc), and fully reprocesses all data, the analysis results are expected to give a clear insight into the level of similarity one can reach with both techniques in terms of station position time series (concerning annual signals etc.). A comparison of the VLBI- and GPS-derived atmospheric loading coefficients with each other and a comparison of the signal derived from these coefficients with existing time series of atmospheric loading signals will allow an assessment of how well they may be interpreted.
