Boat Creek (Gladstone) 2011 hourly air quality...

Period of operation: 1 January to 31 December 2011

• Site was offline from 20 April to 24 July 2011 due to loss of power supply during construction works taking place on the property where the monitoring station is located

Site location: Latitude: -23.8199; Longitude: 151.1538
AS/NZS 3580.1.1:2007 site classification: Neighbourhood
AS/NZS 3580.1.1:2007 compliance (pollutants): Complies fully
AS/NZS 3580.14—2011 compliance (meteorology): Complies fully
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 +10 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

Sulfur dioxide: Ultraviolet fluorescence analyser operated in accordance with AS 3580.4.1—2008

• 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.

Visibility-reducing particles: Nephelometer operated in accordance with AS/NZS 3580.12.1:2001

• Detector spectral response centred at 530 nm.
• Instrument output offset and/or scaled based on calibration and daily zero/span response data
