Rocklea (South East Queensland) 2009 hourly...

Period of operation: 1 January to 31 December 2009
Region: South East Queensland
Site location: Latitude: -27.5358; Longitude: 152.9934
AS/NZS 3580.1.1 site classification: Neighbourhood
AS/NZS 3580.1.1 compliance (pollutants): Complies, except for:

• Isolated trees above height of inlet within 10 metres west of the monitoring site.

AS/NZS 3580.14 compliance (meteorology): Complies, except for:

• Isolated trees within 10 metres west 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 +11 degrees to the sensor output value.

Temperature: Platinum resistance sensor
Relative humidity: Capacitive thin film polymer sensor
Rainfall: Tipping bucket gauge
Solar radiation: Pyranometer
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.

PM10 (to 16 October): 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.

PM2.5 (to 16 October): Tapered Element Oscillating Balance (TEOM) Model 1400AB fitted with Model 8500 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 PM2.5 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 17 October): 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 520 nm.
• Instrument output offset and/or scaled based on calibration and daily zero/span response data.
