1. 1 A European Network for an Environmentally Compatible Air Transport System (ECATS) University of Athens’ contribution Contact: Professor Costas Helmis chelmis@phys.uoa.gr Airports affect strongly local air quality. Aviation emits pollutants at atmospheric layers characterized by low concentrations and large residence times. Moreover, aviation produces clouds (condensation trails) and affects natural clouds. Three Thematic Areas of interest are defined in the frame of ECATS: (1) Airport Air Quality, (2) Engine Emissions & (3) Green flights and scenarios Interpret and study data derived from the ECATS airport campaigns Use ECATS data for modeling purposes, incl. model improvements and coupling Study the effect of aviation on cirrus coverage, conduct capability Gap Analysis Disseminate capabilities and expertise of ECATS partners related to AAQ monitoring and modeling and knowledge of the airport operators’ needs

9. IHU Possible next steps Coordinate exchanges of scientists. Interlink networks. Define collaborative research with the participation of Greek and US groups. Involve US instructors in Master programs offered in Greece. Setup a task force to do all this, starting with an inventory of active groups. Expand to other areas.
