Abstract

The Influence of Oxygenated Fuel Additives on the Air Quality in Urban Areas A contribution to subproject SATURN Frank Kirchner and Bernd C Kriiger Laboratoire de Pollution Atmospherique et Sol, Ecole Polytechnique Federate de Lausanne, CH-1015 Lausanne, Switzerland Introduction The influence of oxygenated fuel additives was investigated in scenario calculations with a three-dimensional photochemical meso-scale model. As an example, an air pollution episode in the Greater Athens Area, Greece, was chosen. For the purpose of the study the atmospheric degradation of MTBE is included in an advanced chemical reaction mechanism, the emission inventory is modified, and the effects on the concentrations of the atmospheric oxidants ozone and PAN are calculated. Model and data description During the MEDCAPHOT-TRACE campaign in 1994 many trace gas measurements have been performed in the Greater Athens Area
