Air Pollution Indicators
![Page 2: Air Pollution Indicators. An indicator should... Be representive for environmental conditions; be simple and easy to interpret; shows trends over time;](https://reader035.fdocuments.us/reader035/viewer/2022070605/5a4d1b2a7f8b9ab059998de0/html5/thumbnails/2.jpg)
An indicator should...• Be representive for environmental
conditions;• be simple and easy to interpret;• shows trends over time;• shows contributions from sectors or
individual components;• be consistently used within the DPSIR-chain;• have a target value.

Assessment information D riving forces (economic sectors:
transport, combustion, solvent use)
P ressures (emissions: VOC & NOx)
S tate (air quality: ozone exceedances)
I mpacts (health, ecosystems, materials)
R esponses (policies, measures)

• Indicators will form building blocks of main EEA reports (Environmental Signals, TERM/EERM, Kiev, ..)
• Core set vs sub-sets to support thematic reports

Indicators - current set• Climate change
– policy update– emissions CO2 & non-CO2– temperature/precipitation change
• Stratospheric Ozone– ozone column– potential Cl– UV– production ODS, HCFC

AP Indicators - current setFocus on• Pressure & State• Urban Air Quality• Acidification• Pollutants from first DD + Ozone• retrospective (Env Sign)• Policy Update

AP Indicators - current set• Emission indicators
– information on trends (1980-present)– information on sector contributions– aggregated information on theme:
• ground-level ozone• acidification and eutrophication• pm10 exposure

Pressure Problems ?• PM10/PM2.5 -emission data• Consensus on aggregation procedure • Indicator for Urban Air Pollution?• Missing years (now simple interpolation)
• Emissions of toxic pollutants (HM, POP)?
![Page 15: Air Pollution Indicators. An indicator should... Be representive for environmental conditions; be simple and easy to interpret; shows trends over time;](https://reader035.fdocuments.us/reader035/viewer/2022070605/5a4d1b2a7f8b9ab059998de0/html5/thumbnails/15.jpg)
Air Pollution Indicators• Air Quality
– (urban) population exposure to• ozone• SO2• NO2• particulate (PM10)
– exceedance of critical loads (EMEP)• acid• nitrogen input
![Page 16: Air Pollution Indicators. An indicator should... Be representive for environmental conditions; be simple and easy to interpret; shows trends over time;](https://reader035.fdocuments.us/reader035/viewer/2022070605/5a4d1b2a7f8b9ab059998de0/html5/thumbnails/16.jpg)
Env Signals: UAQ• SO2, particulate (TSP, BS, PM10),
NO2, O3• observed data (AirBase, O3-dir)• counting exceedance days• not fully in line with DD• short term limit values

Urban AQ: NO2 NO2: Average number of exceedance days in urban areas
(1h >200 ug/m3). All urban sites excluding urban background stations.

State problems ?• Spatial coverage
– missing regions– urban or/and rural
• harmonisation of MM• stable network• temporal: historic data• most critical LV• model vs measurement
