Aircraft Instrument for Comprehensive Characterization of Aerosol Optical Properties, Part 2: Black and Brown Carbon Absorption and Absorption Enhancement Measured with Photo Acoustic Spectroscopy (2012, background): “2008) and (2) enhanced absorption of BC by lensing radiation through the coating to the BC core (Schnaiter et al. 2005; Bond et al. 2006).”
Limitations in the enhancement of visible light absorption due to mixing state (2006, methodology): “As shown in Table 2, amplification depends on core size alone after xshell becomes greater than 3. Laboratory experiments by Schnaiter et al. [2005] confirm that amplification does not appear to increase beyond a value of about 2. [40] Unlike the case of small cores and large shells discussed earl”
Aerosol light absorption and its measurement: A review (2009, background): “The inclusion of carbonaceous aerosols into the radiative transfer component of climate models presents several challenges: (1) aerosol light absorption can add a heating term to the cooling term of nonabsorbing aerosols, (2) carbonaceous aerosols can be non-spherical and inhomogeneous with combusti”
Coatings and their enhancement of black carbon light absorption in the tropical atmosphere (2008, methodology): “Optically significant coatings can enhance the absorption of solar radiation by BC aerosol [Jacobson, 2006; Lesins et al., 2002; Schnaiter et al., 2005; Mikhailov et al., 2006; Bond et al., 2006], perhaps by a factor 2, thereby increasing its direct climate forcing.”
Effects of Mixing State on Black Carbon Measurements by Laser-Induced Incandescence (2007, background): “Furthermore, experiments (e.g., Schnaiter et al. 2005; Mikhailov et al. 2006) and theoretical calculations (e.g., Fuller et al. 1999) have shown that the absorption cross section increases strongly when EC particles are internally mixed (e.g., coated by non-refractory materials).”
Exploiting simultaneous observational constraints on mass and absorption to estimate the global direct radiative forcing of black carbon and brown carbon (2014, background): “In addition, this coating or internal mixing can enhance the absorption of solar radiation (Fuller et al., 1999; Schnaiter et al., 2005; Bond and Bergstrom, 2006); therefore the aging process is important”
Mass Absorption Cross-Section of Ambient Black Carbon Aerosol in Relation to Chemical Age (2009, background): “BC MAC is reported to be dependent on BC mixing state in many studies (Gunter et al. 1993; Martins et al. 1998; Saathoff et al. 2003; Schnaiter et al. 2003, 2005; Doran et al. 2007).”
Variability in morphology, hygroscopicity, and optical properties of soot aerosols during atmospheric processing (2008, background): “In addition, previous experimental studies examined the optical properties of soot with coating of organic carbon or water (19, 20).”
On the attribution of black and brown carbon light absorption using the Ångström exponent (2013, background): “Absorption enhancements of this nature have been observed in some laboratory and field studies (e.g. Cappa et al., 2012; Cross et al., 2010; Schnaiter et al., 2005; Lack et al., 2012b, 2009).”
Simulating the evolution of soot mixing state with a particle-resolved aerosol model (2008, background): “[2003]; Schnaiter et al. [2005]; Bond et al. [2006]. Measurements show that atmospheric soot particles are internally mixed with other aerosol species in varying proportions, and that the hydrophobic portion of the aerosols decreases significantly as the distance from the sources increases [Andreae ”
Aerosol Mixing State: Measurements, Modeling, and Impacts (2019, methodology): “However, Schnaiter et al. (2005) also pointed out that closure for other quantities such as the single-scattering albedo, the Ångström RIEMER ET AL.”
Amplification of Light Absorption of Black Carbon by Organic Coating (2010, methodology): “The maximum γ of 2.0 was also observed by soot coated with secondary organic aerosol (Schnaiter et al. 2005).”
Efficacy of climate forcings (2005, background): “Absorption by BC was increased a factor of two over that calculated for external mixing to approximate enhancement of absorption that accompanies realistic internal mixing of BC with other aerosol compositions [Chylek et al., 1995; Schnaiter et al., 2005].”
