Verified hourly air pollutant monitoring data and meteorological data prepared and published annually by the Ministry of Environment. These data sets contain quality-assured hourly readings from air quality monitoring stations across B.C., from 1980 up to the end of 2017. All data are in Pacific Standard Time.

Data files are available for: Pollutant Data:
  • AQHI - Air Quality Health Index
  • Carbon monoxide (CO) in parts per million (ppm)
  • Hydrogen sulfide (H2S) and Total reduced sulfur (TRS) in ppb
  • Nitric oxide (NO) in parts per billion (ppb)
  • Nitrogen dioxide (NO2) in ppb
  • Sulfur dioxide (SO2) in ppb
  • Ground-level ozone (O3) in ppb
  • PM2.5 (particulate matter with diameter of 2.5 micrometres or less) in micrograms per cubic metre (ug/m3)
  • PM10 (particulate matter with diameter of 10 micrometres or less) in ug/m3
Meteorological Data:
  • Air Temperature (TEMP) in degrees Celsius (°C)
  • Relative Humidity (HUMIDITY) in percent (%)
  • Wind Speed (WSPD) in meters per second (m/s)
  • Wind Direction (WDIR) in degrees from true north/azimuth (°)
  • Precipitation (PRECIP) in millimeters (mm)
  • Barometric Pressure (PRESSURE) in kilopascals (kPA) or millibars (mb)
Statistical Summary:

Contains the annual percentiles, means, exceedance counts of the hourly validated PM2.5, PM10, Ozone, NO, NO2, SO2, CO, TRS and H2S.
