Lower Mainland Region EPD

Air Quality Data

The Lower Mainland Region's Ambient Air Quality Sampling Program is composed of a combination of continuous and non-continuous gas, particulate and meteorological monitors. In addition to monitoring undertaken by the Ministry of Environment, ambient air quality monitoring is also undertaken by industry when required as a condition of their Environmental Management Act discharge permit.

Ambient air quality monitors and meteorological stations currently operating within the Lower Mainland Region are listed in the table below. Air quality data from the stations noted below can be accessed by clicking on the station name in the table, or by going to Air Quality Online.
