Abstract:
Measurements of volatile organic compounds (VOCs) were collected using an Ionicon 4000 Proton Transfer Reaction Time of Flight Mass Spectrometer (PTR-ToF-MS). Measurements were taken at Cataract Scout Park, Appin, N.S.W. (34°14'42.29"S 150°49'24.97"E) from an inlet 10 m above ground level as part of the Characterizing Organics and Aerosol Loading over Australia (COALA-2020) campaign. The campaign ran from mid-January to mid-March, 2020, with the instrument running from early February. Sample air was drawn down a 20 m PTFE inlet line with a bypass pump (flow rate 1.5 - 3 L min-1). Calibration occurred in situ using standard cylinders for the compounds reported below. Calibration uncertainty is ±20%. Additional compounds may be available on request. Measurements were processed using the Ionicon PTR-MS Viewer software. Measurements from February 2 - February 7 have been corrected to account for an identified inlet leak. A flat subtraction was applied, and resulting compound offsets are provided in the parameter comments. Data from February 7 – February 16 have been removed due to identified leak requiring greater corrections.
