Notes

b_sp (CE neph) -- continuous measurements (between listed times) of light scattering coefficient for aerosols measured with UW/CE nephelometer.
b_ap (OEC) -- light-absorption coefficient derived from long-path optical extinction cell and b_sp(CE neph).
b_ap (PSAP) -- continuous measurements (between listed times) of light-absorption coefficient (due to graphitic carbon) measured by Particle Soot Absorption Photometer
Humidigraph -- approximate times at which humidigraph was scanned from 30 to 90% relative humidity to obtain measurements of the aerosol humidification factor.
A³ -- continuous measurements (between listed times) with Aerosol Asymmetry Analyzer, which provides a measure of degree of non-sphericity of the aerosol.
The single-scattering albedo of smoke is derived frmo b_ap (OEC) and b_sp (CE neph) measurements. In some cases multiple plumes were transected, but the single-scattering albedo for each plume can be derived.
The single-scattering albedo of background air is derived from b_ap (PSAP) and b_sp (CE neph).
