Springwood (South East Queensland) 2021 hourly air quality and meteorological data

Period of operation: 1 January to 31 December 2021
Site location: Latitude: -27.6125; Longitude: 153.1359
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies, except for:

• Trees above height of PM10/PM2.5 inlets within 5 metres south and west of the monitoring site.

AS/NZS 3580.14 compliance (meteorology): Complies, except for:

• Located below the upper level of a ridge running roughly northwest-southeast.
• Trees within 10 metres of the monitoring site (below height of wind sensor).

Wind: Ultrasonic sensor

• Height above ground level: 10 metres.
• 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: 3 metres.

Relative humidity: Capacitive thin film polymer sensor

• Height above ground level: 3 metres.

Rainfall: Vaisala RAINCAP® precipitation sensor

• Height above ground level: 10 metres.

Barometric pressure: Capacitive silicon sensor

• Height above ground level: 3 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.

Oxides of nitrogen (from 13 May): Chemiluminescence analyser operated in accordance with AS/NZS 3580.5.1

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

Sulfur dioxide: Ultraviolet fluorescence analyser operated in accordance with AS 3580.4.1

• 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.
