Measurements of PM10 a contribution from EIONET Roel van Aalst Steinar Larssen

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)

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.
