Pimlico (Townsville) 2009 hourly air quality and meteorological data
datastore ActivePeriod of operation: 1 January to 31 December 2009
Region: Townsville
Site location: Latitude: -19.2871; Longitude: 146.7813
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:
- Isolated trees within 20 metres of the monitoring site.
- Three storey building located within 30 metres south 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
- Sensor mounted in non-aspirated radiation shield 4 metres above ground level – under still conditions reported temperature can be higher than actual.
Ozone: UV absorption analyser operated in accordance with AS/NZS 3580.6.1
- Instrument output offset and/or scaled based on calibration and daily zero/span response data.
Oxides of nitrogen: Chemiluminescence analyser operated in accordance with AS/NZS 3580.5.1
- Instrument output offset and/or scaled based on calibration and daily zero/span response data.
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.
