9. AAQC Goals: 1
Determine specific issues related to aerosols and clouds that are common to the topics of climate, air quality and human health
Determine the most pressing measurement and modelling needs in these areas and develop specific programmes for addressing them

10. AAQC Goals: 2
Devise joint measurement and modelling strategies that will produce information that is necessary and useful in all three areas
Link with the horizontal activities within ACCENT to create a forum for information exchange between the air quality, health and climate communities

11. AAQC Goals: 3
Compile and make available a summary of current nationally-funded research programmes in the areas of aerosols and clouds
Support ACCENT-related activities within the community

12. AAQC Activities
A series of focused workshops aimed at producing plans for common research strategies that will involve the climate, air quality, health, measuring and modelling communities
A compilation of national research programmes in aerosols, clouds, air quality and climate
