Measurements of PM10a contribution from
EIONET
Roel van Aalst
Steinar Larssen
EMEP particulates programme
Level
1. All EMEP sites, start now, time resolution 24h
2. 5-10 EMEP sites, start 2002+), time resolution 24h
3. Research projects, campaigns, higher time resolution (< 2-3 h)
EMEP particulates programme
• PM10 CEN 12341 level 1
• PM2.5 CEN 2.5 level 1
• PM1.0 level 1
• Number size distribution level 3
plus an extensive programme of chemical measurements
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.
