Description

Verified hourly air pollutant monitoring data and meteorological data prepared and published annually by the Ministry of Environment. These data sets contain **quality-assured air quality hourly readings from 1980 up to the end of 2025 and quality-assured meteorological hourly readings from 1980 up to the end of 2024** from air quality monitoring stations across British Columbia. All data are in Pacific Standard Time.
