PHOTOCHEMICAL OXIDANT CONTROL STRATEGIES IN EUROPE: A 19 DAYS' CASE STUDY USING A LAGRANGIAN MODEL WITH CHEMISTRY.
Abstract
The trajectory model with atmospheric chemistry developed by NILU, University of Oslo and DNMI (EMEP) has been applied to calculate the oxidant concentration at 9 receptor points in South Scandinavia in the period 26 August to 14 September 1980. The calculations show ozone concentrations exceeding 100 ppbv at the receptor points are efficiently reduced through reduction of European HC emissions, while reduction of NOx or NOx and HC in combination is much less efficient to control ozone.
