The purpose of QUEST is to quantify aerosol nucleation in the European boundary layer atmosphere. Continuous measurements and intensive field campaigns will be carried out in three different locations: Boreal (Finland), polluted Southern European (Italy), and coastal (Ireland). Prior measurements indicate that the nucleation mechanisms are somewhat different in each location. The objectives of the measurements are to fill in gaps that exist in the understanding of chemical and physical pathways leading to formation of new particles. Aircraft measurements will be performed in order to gain information of the vertical and horizontal extent of nucleating events. Parameterised representations of the nucleation mechanisms will be implemented in an European scale model in order to determine the source strength of new aerosol particles.
