Expt. C with gas-phase hydroxyacetone, photolysis, cloud processing, and HOOH oxidation with AS/glcyine seed particles in the CESAM chamber. HA addition, two water vapor additions, start of chamber illumination, start of continuous HOOH addition, and 2 cloud events are labeled. Panel a: total organic carbon readings and mass absorption coefficients at 365 nm from PILS/waveguide UV–vis, color coded to axes. b: chamber RH and droplet spectrometer counts (data ends at 11:15), color coded to axes. c: water-corrected PTR-ToF-MS data (m/z 75 HA, red line; m/z 33 HOOH frag, blue dotted line). d: Dilution- and wall-loss-corrected SMPS total aerosol mass (assuming density = 1 g cm–3) and counts, color-coded to axes. e: CAPS-ssa data at 450 nm (mass-corrected extinction, blue line; mass-corrected scattering, black line; single-scattering albedo, red dots; albedo measured immediately after instrument autozero, red triangles.
