Short summary

Mixing ratios of NO₂ and HCHO in the free troposphere are obtained from MAX-DOAS measurements at two mountain stations at midlatitudes and in the tropics using a modified geometrical approach. The method is applied in the UV wavelength range and, thus, allows the detection of HCHO mixing ratios, in addition to NO₂. We find that mixing ratios of both species are increased in the tropical free troposphere due to biomass burning.
