PM10 levels in Austria 2005

PM10 characteristics in Austria Large spatial variability due to topography and dispersion conditions High PM10 levels in basins and valleys in the Southern Alps and in the Lowlands south-east of the Alps – very adverse dispersion conditions High PM10 levels in the north-eastern and south-eastern Lowlands – high contribution by medium- to long-range transport from Eentral-Eastern Europe Lower PM10 levels and less long-range transport in the north-western Lowlands – more favourable dispersion conditions Distinct vertical gradient – low PM10 concentrations in elevated regions

Urban PM10 concentrations

Regional and long-range Transport Investigation of long-range transport and regional accumulation by combination of backward-trajectories and EMEP emission inventory Typical situations of transport from importand cource regions in central eastern Europe.

Information stored in data-base After any data checking and correction, the following information is stored in the AQ data-base (on a half-hourly time basis): Final (corrected) half-hour mean values original half-hour mean values (as transmitted from the monitoring station) Validity flags Data check flags Information about corrections and changes: reason of correction (from a picklist) time who did it Zero- and span-values Status bits
