Station overview—Hopeland

Monitoring at Hopeland began in February 2015 to assess air quality in close proximity to an area of intensive coal seam gas (CSG) production run by Origin Energy. This monitoring station is managed by CSIRO’s GISERA as part of the Surat Basin Air Quality study. Environmental consultants operate the monitoring network on behalf of CSIRO/GISERA. Method and data validation is overseen by CSIRO.

About air quality categories

Air quality categories are used to make it easier to interpret air quality data by reducing the complexity associated with different pollutant concentration units and air quality guideline values.

Each air quality measurement from a monitoring station is assigned an air quality category rating based on comparison of the measurement value against the relevant air quality guideline. Five colour-coded air quality categories are used, being 'Good' (green), 'Fair' (yellow), 'Poor' (orange), 'Very Poor' (red) or 'Extremely Poor' (dark red). Values greater than the air quality guideline will be appear as ‘Poor’, ‘Very Poor’ or ‘Extremely Poor’.

About these parameters

Particle PM2.5

Airborne particles less than 2.5 micrometres in diameter, referred to as PM2.5, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.

The guideline for Particle PM2.5 is 50µg/m³ (1hr avg) and 25µg/m³ (24hr avg).

Particle PM2.5 is measured in micrograms per cubic metre.

Particle PM10

Airborne particles less than 10 micrometres in diameter, referred to as PM10, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.

The guideline for Particle PM10 is 100µg/m³ (1hr avg) and 50µg/m³ (24hr avg).

Particle PM10 is measured in micrograms per cubic metre.

More information about Particle PM10

Particles TSP

Airborne particles up to about 100 micrometres in diameter are referred to as TSP (total suspended particles). These particles are generated by combustion and non-combustion processes, including windblown dust, sea salt, earthworks, mining activities, industrial processes, motor vehicle engines and fires.

The guideline for Particles TSP is 100µg/m³ (1hr avg) and 80µg/m³ (24hr avg).

Particles TSP is measured in micrograms per cubic metre.

Carbon monoxide

Carbon monoxide is a colourless, odourless gas formed when substances containing carbon (such as petrol, gas, coal and wood) are burned with an insufficient supply of air. It has serious health impacts on humans and animals, especially those with cardiovascular disease.

The guideline for Carbon monoxide is 9ppm (8hr avg).

Carbon monoxide is measured in parts per million.

More information about Carbon monoxide

Nitrogen dioxide

Nitrogen dioxide is an acidic and highly corrosive gas. Nitrogen oxides are critical components of photochemical smog. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease and affect the senses.

The guideline for Nitrogen dioxide is 0.08ppm (1hr avg).

Nitrogen dioxide is measured in parts per million.

More information about Nitrogen dioxide

Ozone

Ozone is a colourless, highly reactive gas with a distinctive odour. The upper atmosphere ozone layer (at altitudes of 15–35km) protects the earth from harmful ultraviolet radiation from the sun. The ozone layer reduction represents a global atmosphere issue.

The guideline for Ozone is 0.1ppm (1hr avg).

Ozone is measured in parts per million.

Wind direction

When high pollutant concentrations occur at a monitoring station, wind data records can determine the general direction and area of the emissions. Identifying the sources means planning to reduce the impacts on air quality can take place. The measurement indicates the direction the wind is coming from.

Wind direction is measured in degrees.

More information about Wind direction

Wind speed

When high pollutant concentrations occur at a monitoring station, wind data records can determine the general direction and area of the emissions. Identifying the sources means planning to reduce the impacts on air quality can take place.

Wind speed is measured in metres per second.

Humidity

Like temperature and solar radiation, water vapour plays an important role in many thermal and photochemical reactions in the atmosphere.

Humidity is measured in percentage.

More information about Humidity

Temperature

Measuring temperature supports air quality assessment, air quality modelling and forecasting activities.

Temperature is measured in degrees Celsius.

More information about Temperature

Solar radiation

Measuring solar radiation is beneficial for modelling photochemical smog events, as the intensity of sunlight has an important influence on the rate of the chemical reactions that produce the smog. The cloudiness of the sky, time of day and geographic location all affect sunlight intensity.

More information about Solar radiation

Rainfall

Rain has a ‘scavenging’ effect when it washes particulate matter out of the atmosphere and dissolves gaseous pollutants. Removing particles improves visibility. Where there is frequent high rainfall, air quality is generally better.
