The Gap (Mount Isa) 2010 hourly air quality and meteorological data

Period of operation: 1 January to 31 December 2010
Site location: Latitude: -20.7264; Longitude: 139.4977
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies fully
AS/NZS 3580.14 compliance (meteorology): Complies, except for:

• Buildings higher than wind sensor located within 20 metres north east 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

• Height above ground level: 3 metres.

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

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

PM10: Tapered Element Oscillating Balance (TEOM) Model 1400AB operated in accordance with AS 3580.9.8

• 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/m^3 are removed and concentrations between -0.5 µg/m^3 and 0.0 µg/m^3 are set to 0.0 µg/m^3.
