2. EMEP particulates programme
Level
All EMEP sites, start now, time resolution 24h
5-10 EMEP sites, start 2002+), time resolution 24h
Research projects, campaigns, higher time resolution (< 2-3 h)

3. EMEP particulates programme
PM10 CEN level 1
PM2.5 CEN level 1
PM level 1
Number size distribution level 3
plus an extensive programme of chemical measurements

4. Needs Urban and local stations are not in the EMEP programme
These are needed for health impact assessment as foreseen in the CLRTAP.
This could be an obvious contribution of EIONET to the EMEP programme.
