Air Quality Monitoring Network Newcastle Autumn 2021 seasonal newsletter

Air quality in the Newcastle region was predominantly good during autumn 2021. Daily particle levels were within national benchmarks for 97% of the time at Stockton and 100% of the time at all other stations. Stockton particle levels are affected by sea salt due to its proximity to the coast. Hourly particle levels were in the good to fair air quality categories from 99.1% to 100% of the time throughout the region. Regional air quality continued to improve compared to recent bushfire and drought-impacted years.
