- No breach of national air quality standards occurred in October 2023.
- The Customs Street city centre site recorded the highest levels of NO2 and SO2 concentrations in October.
- The average NO2 concentration recorded within the first 10 months of this year at the Customs Street site is 16% lower than the same period for the previous year. It is unclear what caused the decrease in the recorded NO2 levels at this site.
It is important to note that air quality at a monitoring site can vary from year to year due to weather and other influences (See Auckland air quality report, October 2021). For a brief short-term trend analysis of key pollutants concentration changes, please see Table 2.
