Queensland 2019 hourly PM2.5 data

Period of reporting: 1 January to 31 December 2019

Monitoring sites: Cannon Hill, Collingwood Park, Fisherman Island, Lytton, Rocklea, South Brisbane, Southport, Springwood, Woolloongabba, Wynnum North, Wynnum West (South East Queensland); Hopeland, Miles Airport, Tara Region 2 (South West Queensland); Boat Creek, Boyne Island, Clinton, Fisherman's Landing, South Gladstone, Targinie (Gladstone region); Blackwater, Moranbah (Central Queensland); West Mackay (Mackay); North Ward (Townsville)

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

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 PM2.5 concentrations down to -5 µg/m^3 resulting from instrument noise at low particle concentrations are reported.

Measurement technique (Cannon Hill, Rocklea, South Brisbane (until 10 June), Southport, Springwood, Woolloongabba (until 13 June), Boat Creek (until 26 March), Boyne Island (until 18 September), Clinton (until 27 March), Fisherman's Landing, South Gladstone, Targinie (until 17 September): 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.

Measurement technique (South Brisbane (from 10 June), Woolloongabba (from 18 June), Boat Creek (from 26 March), Boyne Island (from 18 September), Clinton (from 27 March), Targinie (from 17 September), Blackwater, Moranbah, West Mackay, North Ward): Scattered light spectrometry (TAPI Model 640X) operated in accordance with USEPA equivalence method designation requirements

• Reported concentrations are uncorrected instrument output values.

Measurement technique (Hopeland, Miles Airport, Tara Region 2): Optical light scattering method using Palas Fidas 200 instrument
