Arundel (Gold Coast) 2011 hourly air quality...

Period of operation: 1 January to 31 December 2011
Site location: Latitude: -27.9441; Longitude: 153.3656
AS/NZS 3580.1.1:2007 site classification: Neighbourhood
AS/NZS 3580.1.1:2007 compliance (pollutants): Complies with the exception of the following:

• Three-story building within 20 metres SW of the monitoring site
• Trees above height of inlet within 20 metres W of the monitoring site

AS/NZS 3580.14—2011 compliance (meteorology): Complies with the exception of the following:

• Located on northern side of slope below a ridge running east-west
• Three-story building within 20 metres SW of the monitoring site
• Trees within 20 metres W of the monitoring site
• Temperature and relative humidity sensors located at a height of 10 metres above ground level
• Monitoring shelter located on paved area

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: 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—2011

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

Oxides of nitrogen: Chemiluminescence analyser operated in accordance with AS/NZS 3580.5.1—2011

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

PM10 / PM2.5: Dichotomous Tapered Element Oscillating Balance (TEOM) fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.13—2013

• The FDMS system compensates for the loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• Negative hourly PM10 / PM2.5 concentrations down to -5 µg/m3 resulting from instrument noise at low particle concentrations are reported.
