Hourly ambient nitrogen oxides (NOx, NO2, NO) data in parts per billion from provincial ambient air quality monitoring stations across Nova Scotia up to the end of 2025. This air quality station was established to replace the "Halifax Vogue" air quality monitoring station which ceased monitoring at the end of 2017. The Halifax Vogue station was less than 1 block away from the new "Halifax Johnston" station.
