Deriving brown carbon from multiwavelength absorption measurements: method and application to AERONET and Aethalometer observations (2016, background): “However, recent studies show that some OC can also absorb light, primarily at UV wavelengths (Arola et al., 2011; Hecobian et al., 2010; Chakrabarty et al., 2010; Kirchstetter et al., 2004; Chen and Bond, 2010).”
Optical properties and aging of light-absorbing secondary organic aerosol (2016, background): “Among ambient studies reporting BrC light absorption, high MAC values are almost exclusively reported for aerosols attributed to biomass burning (Kirchstetter et al., 2004; Hoffer et al., 2006; Alexander et al., 2008; Dinar et al., 2008; Chakrabarty et al., 2010; Lack et al., 2013), and the limited ”

Wintertime aerosol properties during foggy and nonfoggy days over urban center Delhi and their implications for shortwave radiative forcing (2006, methodology): “Wavelength dependence of absorption by aerosols have been investigated using a power law relationship of the form babs(l)=K.l � a where K and a are the absorption Angstrom coefficients and a is a measure of spectral dependence of aerosol absorption [ Kirchstetter et al., 2004 ].”
Strong spectral variation of biomass smoke light absorption and single scattering albedo observed with a novel dual-wavelength photoacoustic instrument (2008, background): “stronger light absorption toward the ultraviolet [Kirchstetter et al., 2004].”
Size-resolved measurements of brown carbon in water and methanol extracts and estimates of their contribution to ambient fine-particle light absorption (2013, background): “Reported values range from 0.002 to 0.27 at wavelengths between roughly 500–550 nm (Dinar et al., 2008; Hoffer et al., 2006; Lukacs et al., 2007; Kirchstetter et al., 2004).”
Exploring the observational constraints on the simulation of brown carbon (2017, background): “However, a fraction of OA is also found to efficiently absorb light, predominately at near-UV wavelengths (Kirchstetter et al., 2004; Hecobian et al., 2010; Arola et al., 2011).”

Particulate emissions from commercial shipping: Chemical, physical, and optical properties (2008, background): “Aungstro¨m exponents for absorption give an indication of the contribution of absorbers other than BC, with Au Abs � = 1 indicating mostly BC, while Au Abs > 1 tend to indicate organic matter or dust absorbing in the blue/UV wavelengths [Bergstrom et al., 2007; Kirchstetter et al., 2004 ].”
