#32026D1208EU Air Quality Modelling and Sampling Point Rules
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This decision sets technical rules for how EU countries must use air quality modelling and define the area represented by each air pollution sampling point. It supports the newer EU ambient air quality framework by making modelling methods more consistent across Member States. The practical effect falls mainly on national environmental authorities, air quality agencies, laboratories, and consultants that design monitoring networks or report air pollution data. They will need to apply minimum technical requirements, quality checks, and validation principles when using models for air quality assessment and sampling-point representativeness.

Key Changes
- Sets minimum technical requirements for air quality modelling applications used under the EU ambient air quality framework
- Defines quality assurance and validation principles for modelling used in air quality assessment
- Requires a more comparable approach to determining the spatial representativeness of pollution sampling points across Member States
Obligations
What this law requires
Use air quality modelling applications that meet minimum technical requirements when determining the spatial representativeness of air pollution sampling points.
Apply minimum quality assurance criteria and validation principles to modelling applications used for air quality assessment.
Apply minimum quality assurance criteria and validation principles to modelling applications used to determine the spatial representativeness of sampling points.
Publish information on the spatial representativeness of all air quality sampling points at least every five years.
Clearly define the area represented by each sampling point in zones where air pollutant levels are above the assessment threshold.
