EuroAirnet Stages
Stages
1) Exposure assessment on European scale
based upon monitoring alone
2) Assessment from a combination of
monitoring and modeling
3) To support assessment of effects, and
cost-effective abatement

What has been the impact of
EuroAirnet?
 EuroAirnet has developed in parallel with
DEM/EoI
 EuroAirnet criteria have put emphasis on
the:
 Representiveness issue
• In broad terms: area, city, station selection
• In detail: representativeness area
 Data quality issue
– Methods
– QA/QC procedures
N:\adm\arkiv\overhead\stl
\etc-acc\geneve1.ppt 8
EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE
What has been the impact of
EuroAirnet?
 40 visits to 27 countries
 Countries have considered those issues
– Increased awareness (?)
– Modification of networks (?)
– Strengthening of QA/QC (?)

What has been the impact of
EuroAirnet?
Some examples:
 e.g. Austria, Finland, Germany, Spain :
EuroAirnet is subset of EoI
 e.g. Italy, Norway, UK (?) :
EuroAirnet = EoI

What has been the impact of
EuroAirnet?
Phare/accession countries:
The EAN/DEM process* has resulted in:
 EAN networks in 11 countries
 Regular data reporting to AIRBASE using
DEM
* Work carried out by the ETC-Phare Topic Link

Future of EuroAirnet
 EuroAirnet metadata into DEM
(new EoI)
 Local/national networks are now being
modified according to requirements from
AQ Directives:
Updating of station metadata needed
 ETC will use metadata as much as possible
in annual ”AQ Europe” assessments

EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE
Future of EuroAirnet
Crucial questions:
 How to improve data quality?
 How to improve representativeness?
 How to make AQ monitoring in Europe
more cost effective?
What do you see as further needs:
 Further develop EuroAirnet criteria?
 Continued selection/evaluation process?
 Need for - follow-up from ETC?
regular reminders?
