The Gap (Mount Isa) 2011 hourly air quality and meteorological data

Period of operation: 1 January to 31 December 2011
Site location: Latitude: -20.7264; Longitude: 139.4977
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 with the exception of the following:

• Buildings higher than wind sensor located within 20 metres northeast and east of the monitoring site
• Monitoring shelter located on concreted surface

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 +6 degrees to the sensor output value.

Temperature: Capacitive ceramic sensor
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: Tapered Element Oscillating Balance (TEOM) operated in accordance with AS 3580.9.8—2001

• Measurement values do not compensate for loss of semi-volatile components from the collected particulate matter
• Instrument output values are adjusted in accordance with US EPA equivalence designation method EQPM-1090-079 requirements (scaled by 1.03, offset by +3.0)
• After adjustment, negative hourly PM10 concentrations less than -0.5 µg/m3 are removed and concentrations between -0.5 µg/m3 and 0.0 µg/m3 are set to 0.0 µg/m3
