Lutwyche (Brisbane) 2012 hourly air quality...

Period of operation: 1 January to 2 July 2012 (site closed)
Site location: Latitude: -27.4166; Longitude: 153.0376
AS/NZS 3580.1.1:2007 site classification: Peak (roadway construction works)
AS/NZS 3580.1.1:2007 compliance (pollutants): Complies with the exception of the following:

• Building higher than inlet within 20 metres S of monitoring site

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

• Building higher than wind sensor located within 20 metres S of monitoring site
• Monitoring shelter located on asphalted surface

Wind: Ultrasonic sensor

• Height above ground level: 6 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
Relative humidity: Capacitive thin film polymer sensor
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.
