West Mackay (Mackay) 2019 hourly air quality...

Period of operation: 1 January to 31 December 2019
Site location: Latitude: -21.1596; Longitude: 149.1550
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies fully
AS/NZS 3580.14 compliance (meteorology): Complies fully

Wind: Ultrasonic sensor

• Height above ground: 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 +9 degrees to the sensor output value.

Temperature: Capacitive ceramic sensor
PM10 (to10 October): Tapered Element Oscillating Balance (TEOM) Model 1405 operated in accordance with AS/NZS 3580.9.16 (excluding FDMS requirements)

• Measurement values do not compensate for loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• 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.

PM10/PM2.5 (from 10 October): Scattered light spectrometry (TAPI Model 640X) operated in accordance with USEPA equivalence method designation requirements

• Reported concentrations are uncorrected instrument output values.

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

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