An evaluation of ozone dry deposition in global-scale chemistry-climate models

The paper analyzes ozone dry deposition in 15 global chemistry-climate models, finding that land cover drives substantial regional differences in fluxes. While comparing these models to observations in Europe and North America, the authors found differences of up to a factor of two without a clear systematic bias, highlighting that many models still rely on outdated 'resistance in series' schemes from the 1980s.

• The study identifies that land cover is a primary driver of the substantial differences in ozone dry deposition fluxes observed across an ensemble of 15 global models.
• Comparisons between modelled ozone dry deposition fluxes and measurements at various sites in North America and Europe reveal differences of up to a factor of two, although no clear systematic bias was identified across the examined sites.
• Many atmospheric and Earth system models continue to use 'resistance in series' schemes for representing dry deposition that were developed in the 1980s and fail to incorporate modern field and laboratory-based understanding of the processes.
