Ayr (Ayr) 2014 hourly air quality and meteorological data

URL: https://data.des.qld.gov.au/__data/assets/file/0025/83905/ayr-aq-2014.csv

Period of operation: 1 January to 31 December 2014
Site location: Latitude: -19.5839; Longitude: 147.4059
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:

  • Trees within 15 metres of the monitoring site.

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 +8 degrees to the sensor output value.

Temperature: Capacitive ceramic sensor
PM10 (1 January to 25 November): 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.

PM10 (26 November to 31 December): Tapered Element Oscillating Balance (TEOM) Model 1405 operated in accordance with AS/NZS 3580.9.13 (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.

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.
