Air quality pollutants measurements at Cataract Scout Park, Australia, taken during the COALA-2020 campaign

Measurements of air quality pollutant concentration were collected using a New South Wales Department of Planning, Industry, and Environment Air Quality Monitoring Station (AQMS). Measured variables included relative humidity, ambient temperature, wind speed and direction, particulate matter less than 2.5 µm in diameter (PM2.5), particulate matter less than 10 µm in diameter (PM10), ozone, nitric oxide (NO), nitrous oxide (NO2), oxides of nitrogen (NOx), sulfur dioxide (SO2) and visibility by nephelometer. The station used was identical to those used in the DPIE air quality monitoring network around N.S.W. Details of the instrumentation used can be found here: https://www.environment.nsw.gov.au/topics/air/air-quality-basics/sampling-air-pollution. Measurements were taken at Cataract Scout Park, Appin, N.S.W. (34°14'42.29"S 150°49'24.97"E) as part of the Characterising Organics and Aerosol Loading over Australia (COALA-2020) campaign. Measurements are available from late December, 2019 to mid-March, 2020. Reported measurements are at 1-minute time resolution. Data have been filtered for flagged, outlying and negative values. All gaseous measurements were corrected using overnight zero and span measurements. Ozone was corrected overnight using only zero measurements. It must be noted that the sulfur dioxide record contains some data gaps.
