Scatter plots of H2O (in permil) and CO2 against H2S concentrations showing correlations for the second MultiGAS flights on November 21, 2014. Data between 15:27:45 and 15:43:30 were used to select the period during which the UAV was flying horizontally at altitudes between 2930 and 3040 m. The equations and R 2 values on the right bottom are linear regression line and coefficients of determination, respectively
