Cannon Hill (South East Queensland) 2020 hourly air quality and meteorological data

Period of operation: 1 January to 31 December 2020 (particle measurements impacted by car park development earthworks next to station at times in January)
Site location: Latitude: -27.4654; Longitude: 153.0872
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies fully
AS/NZS 3580.14 compliance (meteorology): Complies, except for:

• Temperature and relative humidity sensors located 10 metres above ground level.
• Rainfall measured by acoustic sensor

Wind sensor: Ultrasonic sensor

• The wind direction sensor is aligned to magnetic north. The reported wind direction is referenced to true north by application of a magnetic declination correction of +11 degrees to the sensor output value.

Temperature: Capacitive ceramic sensor

• Height above ground level: 10 metres.

Relative humidity: Capacitive thin film polymer sensor

• Height above ground level: 10 metres.

Rainfall: Vaisala RAINCAP® precipitation sensor.

• Height above ground level: 10 metres.

Barometric pressure: Capacitive silicon sensor.

• Height above ground level: 10 metres.

Ozone: UV absorption analyser operated in accordance with AS/NZS 3580.6.1

• Instrument output offset and/or scaled based on calibration and daily zero/span response data.

PM10/PM2.5: Dichotomous Tapered Element Oscillating Balance (TEOM) Model 1405-DF fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.13

• The FDMS system compensates for the loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• The reported PM10 and PM2.5 concentrations are calculated from running 1-hour average concentrations updated at six minute intervals.
• Negative hourly PM10/PM2.5 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

TSP: Tapered Element Oscillating Microbalance (TEOM) Model 1405 fitted with TSP inlet and operated in accordance with AS/NZS 3580.9.13 (excluding FDMS requirements)

• Measurement values do not compensate for loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• Negative hourly TSP concentrations less than -0.5 µg/m^3 are removed and concentrations between -0.5 µg/m^3 and 0.0 µg/m^3 are set to 0.0 µg/m^3.
