Global simulation of tropospheric O3-NOx-hydrocarbon chemistry 2. Model evaluation and global ozone budget
Results from a global three-dimensional model for tropospheric O3-NOx-hydrocarbon chemistry are presented and evaluated with surface, ozonesonde, and aircraft measurements. Seasonal variations and regional distributions of ozone, NO, peroxyacetylnitrate (PAN), CO, ethane, acetone, and H2O2 are examined. The model reproduces observed NO and PAN concentrations to within a factor of 2 for a wide r...
متن کاملHeterogeneous Chemistry and Tropospheric Ozone
Ozone is produced in the troposphere by gas-phase oxidation of hydrocarbons and CO catalyzed by hydrogen oxide radicals (HOx ≡ OH + H + peroxy radicals) and nitrogen oxide radicals (NOx ≡ NO+NO2). Heterogeneous chemistry involving reactions in aerosol particles and cloud droplets may affect O3 concentrations in a number of ways including production and loss of HOx and NOx, direct loss of O3, an...

متن کاملGlobal simulation of tropospheric O 3 -NO x -hydrocarbon chemistry: 3. Origin of tropospheric ozone and effects of nonmethane hydrocarbons
A global three-dimensional model of tropospheric O3-NOx-hydrocarbon chemistry is used to investigate the factors controlling ozone concentrations in the troposphere. Model results indicate a close balance between chemical production and chemical loss of ozone in the tropospheric column at all latitudes (except high latitudes in winter). Using separate tracers for ozone produced in the stratosph...
متن کامل1 Heterogeneous Chemistry and Tropospheric Ozone
Ozone is produced in the troposphere by gas-phase oxidation of hydrocarbons and CO catalyzed by hydrogen oxide radicals (HOx ≡ OH + peroxy radicals) and nitrogen oxide radicals (NOx ≡ NO+NO2). Heterogeneous chemistry involving reactions in aerosol particles and cloud droplets can perturb O3 concentrations in a number of ways including production and loss of HOx and NOx, direct loss of O3, and p...
