Targinie (Gladstone) 2009 hourly air quality...

Period of operation: 1 January to 31 December 2009
Region: Gladstone
Site location: Latitude: -23.7743; Longitude: 151.1060
AS/NZS 3580.1.1 site classification: Background
AS/NZS 3580.1.1 compliance (pollutants): Complies fully
AS/NZS 3580.14 compliance (meteorology): Complies, except for:

• Trees within 15 metres north west of the monitoring site.
• Temperature and relative humidity sensors located 10 metres above ground level.
• Rainfall measured by acoustic sensor.

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 +10 degrees to the sensor output value.

Temperature (from 20 January): Capacitive ceramic sensor

• Height above ground level: 10 metres.

Relative humidity (from 30 January): Capacitive thin film polymer sensor

• Height above ground level: 10 metres.

Rainfall (from 30 January): Vaisala RAINCAP® precipitation sensor

• Height above ground level: 10 metres.

Barometric pressure (from 12 May): Capacitive silicon sensor

• Height above ground level: 10 metres.

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/PM2.5: Dichotomous Tapered Element Oscillating Balance (TEOM) Model 1405-DF fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.13

• The FDMS system compensates for the loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• Negative hourly PM10/PM2.5 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

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.
