Air Quality For
Canada
Air Quality is a rating scale for outdoor air in Canada. The lower the
AQI, the better the air quality. Six key air pollutants are monitored:
sulphur dioxide, ozone, nitrogen dioxide, total reduced sulphur
compounds, carbon monoxide and suspended particulates. These pollutants
were chosen because they have an adverse effect on humans and the
environment at high levels. Many provinces has air quality reports
except those that don't have a problem at this time.

The mixing layer is the atmospheric zone near the surface where
pollutants disperse rapidly. The depth of this layer depends on
the temperature and on the stability of the atmosphere at low
level. Lower values of mixing layer depth indicate that the
pollutants will be mixed in a smaller volume of air. Areas with
mixing layer depth below 400 metres are highlighted on the maps. |

The ventilation is an indication of the ability of the atmosphere
to effectively provide "fresh air" over a given point. It is
dependent on the mixing layer depth and the wind speed within that
layer.
Areas with poor ventilation (under 2500m²/s) are highlighted on
the maps. |

Wind Mileage |

The wind mileage is an approximation of the distance a parcel
would travel during the day if moved by the wind. The air quality
will suffer in areas with a low wind mileage values should these
areas become polluted. Areas with wind mileage below 200
kilometres are highlighted on the maps. |
