Period of operation: 1 January to 31 December 2020
Site location: Latitude: -27.4774; Longitude: 153.0281
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies, except for:

  • Equipment located in room on sixth floor of building.
  • Nephelometer inlet located on eastern side of building, 1 metre out from building.
  • PM10 inlet located on building roof above equipment room, 1 metre above roof surface.
  • Building lift shaft higher than PM10 inlet located 8 metres south of inlet.

AS/NZS 3580.14 compliance (meteorology): Complies, with exceptions:

  • Building lift shaft higher than wind sensor and within 10 metres of sensor.
  • Buildings higher than wind sensor located within 40 metres of sensor.

Wind: Ultrasonic sensor

  • Height above roof level: 4 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

  • Height above roof level: 4 metres.

Relative humidity: Capacitive thin film polymer sensor

  • Height above roof level: 4 metres

Rainfall: Vaisala RAINCAP® precipitation sensor

  • Height above roof level: 4 metres

Barometric pressure: Capacitive silicon sensor

  • Height above roof level: 4 metres

PM10 (until 8 January): Tapered Element Oscillating Balance (TEOM) Model 1405-F fitted with Filter Dynamics Measurement System operated in accordance with AS/NZS 3580.9.16

  • The FDMS system compensates for the loss of semi-volatile components from the collected particulate matter.
  • Reported concentrations are uncorrected instrument output values.
  • The reported PM10 concentrations are calculated from running 1-hour average concentrations updated at six minute intervals.
  • Negative hourly PM10 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

PM10/PM2.5 (from 8 January): 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.
