Short summary

We present an evaluation of ocean and snow/ice O₃ deposition in explaining observed hourly surface O₃ at 25 pan-Arctic sites using an atmospheric meteorology/chemistry model. The model includes a mechanistic representation of ocean O₃ deposition as a function of ocean biogeochemical and mixing conditions. The mechanistic representation agrees better with O₃ observations in terms of magnitude and temporal variability especially in the High Arctic (> 70° N).
