South Brisbane (Brisbane) 2011 hourly air...

Period of operation: 1 January to 31 December 2011
Site location: Latitude: -27.4848; Longitude: 153.0321
AS/NZS 3580.1.1:2007 site classification: Peak (roadside)
AS/NZS 3580.1.1:2007 compliance (pollutants): Complies fully
AS/NZS 3580.14—2011 compliance (meteorology): Complies with the exception of the following:

• Wind measurements will be perturbed by elevated ground and roadways to the north and west of the monitoring site

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
Relative humidity: Capacitive thin film polymer sensor
Oxides of nitrogen: Chemiluminescence analyser operated in accordance with AS/NZS 3580.5.1—2010

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

Carbon monoxide: Infrared absorption analyser operated in accordance with AS 3580.7.1—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.

Please note: This dataset was updated to modify carbon monoxide values on 03 May 2018
