Short summary
We present a parameterization method for the conversion of measured trace gas slant column densities into volume mixing ratios along a flight track. Benefits of this method are that it is computationally fast and almost no information on local atmospheric conditions is needed. Application to simulated data and field data show that the method is accurate within 10–15 % and valid for a wide range of atmospheric conditions. Our method can easily be transferred to other trace gases.
