Greenhouse gases measurements at Cataract Scout Park, Australia, taken during the COALA-2020 campaign
Measurements of greenhouse gases were collected using a Fourier transform infrared (FTIR) trace gas and isotope analyser (Spectronus Trace Greenhouse Gas and Isotope Analyser, Ecotech, Knoxfield, VIC, Australia; Griffith et al., 2012). Measurements were taken at Cataract Scout Park, Appin, N.S.W. (34°14'42.29"S 150°49'24.97"E) from an inlet 4.68 m above ground level in eucalypt forest as part of the Characterizing Organics and Aerosol Loading over Australia (COALA-2020) campaign. The instrument was operated with a sample flow rate into the 2.5 L cell of ~0.9 slpm. The instrument was calibrated against a suite of four reference gases traceable to WMO-GAW scales before deployment. Measurements of a target tank were performed every two days during the campaign to monitor instrument drift. Measurements are reported at one-minute time resolution.
