Rocklea (Brisbane) 2011 hourly air quality and...

Period of operation: 1 January to 11 January 2011 (site offline due to flood damage)

• Monitoring site damaged by severe flooding and offline for remainder of year awaiting replacement monitoring station infrastructure

Site location: Latitude: -27.5358; Longitude: 152.9934
AS/NZS 3580.1.1:2007 site classification: Neighbourhood
AS/NZS 3580.1.1:2007 compliance (pollutants): Complies with the exception of the following:

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

AS/NZS 3580.14—2011 compliance (meteorology): Complies with the exception of the following:

• Temperature and relative humidity sensors located at a height of 10 metres above ground level

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—2010

• 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—2010

• Instrument output offset and/or scaled based on calibration and daily zero/span response data

PM10 / PM2.5: Dichotomous Tapered Element Oscillating Balance (TEOM) fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.13—2013

• 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/m3 resulting from instrument noise at low particle concentrations are reported.

Visibility-reducing particles: Nephelometer operated in accordance with AS/NZS 3580.12.1:2001

• Detector spectral response centred at 525 nm.
• Instrument output offset and/or scaled based on calibration and daily zero/span response data
