The THOR model
The data used in the Indicator is collected and calculated by the National Environmental Research Institute in Denmark (NERI) the Department for Atmospheric Environment.

The model is an integrated air pollution monitoring system and can accurately forecast  three-days of air
pollution. By combining the information about
regional and local sources of pollution with
meteorological data it can predict  the air quality
down to an individual city street..

The Environmental Control Agency
In Copenhagen,  the Environmental Control Agency
distributes this data to citizens on this page. There are five categories of pollution: Warning, high, above average, average and below average. The same system is used in the indicator.

One of the air measuring stations is on the street with the heaviest traffic in Copenhagen: H.C. Andersens Boulevard with 70.000 vehicles passing by the city hall
daily. When comparing these measurements
with the prognosis of THOR the model proves itself.
The THOR model has an advantage as  it can calculate
pollution levels locally on more streets in the city.

Harmful substances in the air
Carbon dioxide CO2, contributes to global warming.
Carbon monooxide CO, from gasoline cars substitutes oxygen in the blood.
Nitrogen oxides NOx, Can pose health problems especially to people with asthma or bronchitis.
Ozone O3: Caused by pollution from traffic and industry. Can cause trouble in breathing.
Particles: Especially from diesel cars and by air borne circulation of dust and pollen, causes problems especially for people with respiratory or heart conditions.

The project is made also in relation to a lot of public debate about these issues in Danish media, below you find a selection of articles from the daily newspaper Politiken.
