2. PM10 levels in Austria 2005

3. 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

4. Urban PM10 concentrations

5. 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.

6. Regional and long-range Transport – estimation of contributions to Vienna

7. Chemical composition of PM10

8. 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
