Interactive comment on “ High gas-phase mixing ratios of formic and acetic acid in the High Arctic ” by

This is a well-written and thoughtful manuscript that describes high FA and AA in the Arctic. The authors note some interesting features in the data (correlation to high wind speeds), and then move to examining the sources. Anthropogenic activity is not a source (while the authors have few tracers for anthropogenic activity, I am satisfied by the use of aerosol number in this environment). The authors further demonstrate that partitioning from the snowpack is unlikely using back-of-the-envelope calculations. Attribution of flux to soil emissions is more challenging due to the lack of data, but the authors present a balanced picture of the relevant literature. Similarly, plants are an unlikely source of formic acid. Overall, the authors attribute the elevated formic and acetic acid concentrations to a combination of sources, but cannot point to a clear source or specific insight. However, I suspect this gets to the core of the challenge of modeling
