Short summary
We applied a global sensitivity analysis to the GEOS-Chem chemical transport model analyzing some well-studied tropospheric oxidants for a time period corresponding to an aircraft field campaign. We find modeled results generally agree with measurements when uncertainties in both the model and measurements are taken into account. While model results were largely sensitive to emissions, chemical reaction rates also represented a large source of uncertainty.
