EMEP Task forces;• Emissions and projections• Measurements and modelling• Intercontinental transport

Air pollution including LRTAP: acidification, Eutro pication, photo oxidants, heavy metals, POPs, Aeros ols:inks to Air Quality and Climate change

Basis also for EC legislation

EMEP Chemical Coordinating Centre

• Recommendation of methods, preparation of manuals,

• Field and laboratory intercomparisons,

• Data and metadata collection, validation and dissemination,

• Data interpretation/evaluation,

• Representativeness

• Development of network, capacity building and training

• Develop measurement strategies

Key elements:• Comprehensive and concurrent, • Sustainability, collaboration• High or known quality, • Transperancy, • Air Quality – Climate change• Linking local and global scales• GEOSS, Calval, • Near Real Time/Rapid delivery• Level approach, supersites and campaigns• Scientific involvement, Research infrastructures • Links to GAW, EU and other regional programmes• Handle large variation in parties abilities to

implement
