• Qualitative comparison of Gaussian puff spread parametrisations in terms of time or distance, based on with realistic (i.e. physically sensible or for Starzach data well-matching) and unphysical properties marked with color.

• Time series of total mass emission rate at the Starzach site, calculated from integrated transport divergence according to Eq (5) for the white rectangle downstream fo the groundwater well mofette in Fig 6 (top) and the entire core Starzach mofette area (bottom).
