  2. SCIENTIFIC MOTIVATION • What are the processes controlling air quality in the region? • What is the relative contribution of long-range versus more • local pollution sources? • What is the impact of marine derived trace gases and aerosols • on air quality in New England? • What is the impact of extensive natural emissions in New • England on air quality? • How is regional climate changing? • How are seasonal climate and air quality linked?
