Measurement units: micrograms per cubic metre (ug/m^3)

Measurement technique (Flinders View, Mountain Creek, Auckland Point, Bluff, The Gap): Tapered Element Oscillating Balance (TEOM) Model 1405 operated in accordance with AS/NZS 3580.9.16 (excluding FDMS requirements)

• Measurement values do not compensate for loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• 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.

Measurement technique (Brisbane CBD (until 8 January)): Tapered Element Oscillating Balance (TEOM) Model 1405-F fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.16

• 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 PM10 concentrations are calculated from running 1-hour average concentrations updated at six minute intervals.
• Negative hourly PM10 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

Measurement technique (Lytton, Wynnum North, Wynnum West): Dichotomous Tapered Element Oscillating Balance (TEOM) Model 1405-D operated in accordance with AS/NZS 3580.9.13 (excluding FDMS requirements)

• Measurement values do not compensate for loss of semi-volatile components from the collected particulate matter.
• Reported concentrations are uncorrected instrument output values.
• Negative hourly PM10 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

Measurement technique (Cannon Hill, Rocklea, Southport, Springwood, Fisherman's Landing, South Gladstone: Dichotomous Tapered Element Oscillating Balance (TEOM) Model 1405-DF fitted with Filter Dynamics Measurement System (FDMS) operated in accordance with AS/NZS 3580.9.16

• 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 PM10 concentrations are calculated from running 1-hour average concentrations updated at six minute intervals.
• Negative hourly PM10 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.
