Short summary

We present measurements of ambient ions in the free troposphere and lower stratosphere over Europe in spring 2020. We observed nitrate and hydrogen sulfate, amongst others. From their ratio, the number concentrations of gaseous sulfuric acid were inferred. Nitrate increased towards the stratosphere, whilst sulfuric acid was slightly decreased there. The average values for sulfuric acid were 1.9 to 7.8 × 10⁵ cm^-3. Protonated pyridine was identified in an altitude range of 4.6 to 8.5 km.
