MODELLING OF PHOTOCHEMICAL OXIDANTS AND PRECURSORS IN EUROPE 28 MAY-3 JUNE, 1982

Abstract

The Norwegian lagrangian long-range transport model with CBM-X chemistry has been applied to calculate the concentration of ozone and other photochemical oxidants at 14 measuring sites in Europe 28 May - 3 June 1982. Temperature, mixing height, cloud cover, dry removal and initial conditions are important for the calculated ozone concentrations. Reduction of voe-emissions is calculated to reduce ozone. Reduction of NOx or NOx and voe together may also reduce ozone.
