Upper Hunter region
The monitoring region in the Upper Hunter runs from Merriwa in the north-west to near Broke in the south-east, across the local government areas of Upper Hunter, Muswellbrook and Singleton. Download the network site information (XLSX 44KB).
The Upper Hunter Air Quality Monitoring Network was created by the Department of Climate Change, Energy, the Environment and Water, in partnership with the Upper Hunter coal and power industries, in response to community concern about the effect of coal mining on air quality in the region. The monitoring stations were established between 2010 and 2012.
Monitoring
All monitoring stations report on:
- PM10 particles (particles with a diameter of 10 micrometres (µm) or less)
- wind speed
- wind direction
- temperature and humidity.
Four stations (Muswellbrook, Singleton, Merriwa and Camberwell) also report on particles with a diameter 2.5 µm or less (PM2.5). Reporting for nitrogen dioxide (NO2) and sulfur dioxide (SO2) data is undertaken at 3 stations (Muswellbrook, Singleton and Merriwa), and reporting of rain data is undertaken at 7 stations.
Reporting
We provide hourly values of pollutant levels measured at these stations. For 3 stations, Muswellbrook, Singleton and Merriwa, we provide more detailed air quality data.

Five-year network review
The second 5-year review of the Upper Hunter Air Quality Monitoring Network) was published in 2022. This review covers the network operations between 2017 and 2021 inclusive.
The first review of the network, which reviews the initial 5 years of operation up to 2016, was undertaken in 2017.

Research studies
The Upper Hunter Valley Particle Characterization Study was carried out in 2012 to study the composition of fine particles 2.5 microns and smaller in diameter (PM2.5) in the towns of Singleton and Muswellbrook.

Advisory committee
In September 2010, the Upper Hunter Air Quality Monitoring Network Advisory Committee was established. The charter of the committee is to advise the Department of Climate Change, Energy, the Environment and Water and the Environment Protection Authority on matters specifically related to the design and operation of the Upper Hunter Air Quality Monitoring Network.
