Queensland 2017 hourly PM10 data

Period of reporting: 1 January to December 2017

Monitoring sites: Brisbane CBD, Cannon Hill, Flinders View, Lytton, Mountain Creek, Rocklea, South Brisbane, Springwood, Woolloongabba, Wynnum North, Wynnum West (South East Queensland), Auckland Point, Boat Creek, Boyne Island, Clinton, Fisherman's Landing, South Gladstone, Targinie (Gladstone region), West Mackay (Mackay), Moranbah (Moranbah), Townsville Coast Guard, North Ward (Townsville), The Gap (Mount Isa)

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

Measurement technique (Townsville Coast Guard - to 24 March): 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.

Measurement technique (Flinders View, Mountain Creek, Auckland Point, West Mackay, Moranbah, 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): 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, South Brisbane, Springwood, Woolloongabba, Boat Creek, Boyne Island, Clinton, Fisherman's Landing, 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 3580.9.16

• 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 (Townsville Coast Guard - from 7 November, North Ward): Scattered light spectrometry (TAPI Model 640X) operated in accordance with USEPA equivalence method designation requirements

• Reported concentrations are uncorrected instrument output values.
