The Kolmogoroff–Smirnoff test reveals that the distribution functions from SPURT and MOZAIC trace gases differ from each other with a confidence of 95%. A variance analysis shows a different variability character in both trace gas data sets. While the SPURT data only contain atmospheric processes variable on a diurnal or synoptical timescale, MOZAIC data also reveal processes, which vary on inter-seasonal and seasonal timescales. The SPURT data set does not represent the full MOZAIC H₂O variance in the UT/LS for climatological investigations, whereas the variance of O₃ is much better represented. SPURT H₂O data are better suited in the stratosphere, where the MOZAIC RH sensor looses its sensitivity.
