Queensland 2011 hourly PM2.5 data

Period of reporting: 1 January to 31 December 2011
Monitoring sites: Arundel, Lutwyche, Rocklea, South Brisbane, Springwood, Woolloongabba, Wynnum (South East Queensland); Boat Creek, Boyne Island, Clinton, South Gladstone, Targinie (Gladstone region)
Measurement units: micrograms per cubic metre (ug/m^3)
Measurement technique (Springwood, Wynnum): 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.
• Reported values are unadjusted instrument output values as per the requirements of the Air NEPM Technical Paper on Monitoring for Particles as PM2.5.
• 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.

Measurement technique (Arundel, Lutwyche, Rocklea, South Brisbane, Woolloongabba, Boat Creek, Boyne Island, Clinton, South Gladstone, Targinie): 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.
• The reported PM2.5 concentrations are calculated from running 1-hour average concentrations updated at six minute intervals.
• Negative hourly PM2.5 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.
