Measurements of photosynthetically active radiation (PAR) were taken using an Apogee SQ-110 sensor (Apogee Instruments, Inc., Logan, UT, USA). 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 Characterizing Organics and Aerosol Loading over Australia (COALA-2020) campaign. The sensor was placed on an exposed railing 4.35 m above ground level. Measurements were taken at 1 Hz resolution. The measurements reported here are 1-minute averages of 1 Hz measurements. Both PPFD (Photosynthetic Photon Flux Density, measured wavelength range 400-700 nm) and YPFD (Yield Photon Flux Density, measured wavelength range 360-760 nm) are reported.

COALA-2020 was funded by Australia's National Environmental Science Program through the Clean Air and Urban Landscapes hub
