• Aerosol light absorption and its measurement: A review (2009, background): “The heating of light absorbing aerosols changes the local atmospheric temperature, which influences relative humidity, atmospheric circulation and stability and thereby cloud formation and lifetime (semi-direct effect) [7,8].”
• Emissions from the laboratory combustion of wildland fuels: Particle morphology and size (2006, background): “of clouds due to light absorption and heating by BC (semidirect effect) [Ackerman et al., 2000; Lohmann and Feichter, 2001].”
• Direct radiative effect of aerosols as determined from a combination of MODIS retrievals and GOCART simulations (2004, background): “As suggested by several recent studies, a combination of large atmospheric absorption and surface cooling can increase the stratification of lower atmosphere and has important implications for atmospheric circulations, global climate, hydrology cycle, and air pollution [e.g., Ramanathan et al., 2001”
• Radiative effects of aerosols on the evolution of the atmospheric boundary layer (2002, result): “Since all observed aerosols are at least moderately absorbing, our results are consistent with the recent cloud-burning observations related to absorbing aerosols [Ackerman et al., 2000].”
• Precipitating Condensation Clouds in Substellar Atmospheres (2001, methodology): “3b of Ackerman et al. 2000b).”
• Climate forcings in Goddard Institute for Space Studies SI2000 simulations (2002, background): “[51] Aerosols cause climate forcing in several ways: (1) the direct effect of aerosols on solar and infrared radiation, which has been studied extensively, (2) the semidirect-direct effect on clouds, as absorbing aerosols heat the atmosphere and thus tend to reduce large-scale cloud cover [RF-CR; Ac”
• A study of internal and external mixing scenarios and its effect on aerosol optical properties and direct radiative forcing (2002, background): “Of particular interest is the treatment of black carbon since its high absorption coefficient makes it particularly sensitive to mixing assumptions and a contributor to radiative heating [e.g., Jacobson, 2000, 2001a; Ackerman et al., 2000].”
• Inferring black carbon content and specific absorption from Aerosol Robotic Network (AERONET) aerosol retrievals (2005, background): “Absorbing aerosols may also be responsible for a second indirect effect, whereby clouds evaporate more rapidly because of absorbing haze and cloud condensation nuclei [ Ackerman et al., 2000 ].”
• Variability in morphology, hygroscopicity, and optical properties of soot aerosols during atmospheric processing (2008, background): “Also, on the basis of mesoscale model simulations, absorption of solar radiation by internally mixed soot aerosols causes warming in the middle atmosphere and reduction in cloudiness over the tropics (4).”
• Aerosol–climate interactions in the Norwegian Earth System Model – NorESM1-M (2012, background): “The semi-direct effect is potentially positive due to decreased low level cloudiness when increased aerosol absorption reduces relative humidity (Hansen et al., 1997) or due to reduced boundary-layer turbulent fluxes and cumulus clouds (Ackerman et al., 2000).”
• Aerosol-cloud interaction inferred from MODIS satellite data and global aerosol models (2006, background): “A wide range of measurements show that anthropogenic aerosol alter clouds and their optical properties (Ackerman et al., 2000; Andreae et al., 2004; Kaufman et al., 2005a; Kim et al., 2003; Koren et al., 2004, 2005; Penner et al., 2004; Ramanathan et al., 2001; Rosenfeld, 2000; Rosenfeld et al.,…”
• Radiative forcing of climate change (2002, background): “Ackerman et al. (2000) point out that this can warm the atmosphere and “burn off” clouds.”
• Evaluation of the aerosol indirect effect in marine stratocumulus clouds : droplet number, size, liquid water path, and radiative impact (2005, result): “respectively. The two higher values are still an order of magnitude lower than those used for calculations of the ‘‘semidirect’’ effect by Ackerman et al. [2000] to represent more polluted conditions in the Indian Ocean.”
• Global observations of aerosol‐cloud‐precipitation‐climate interactions (2014, background): “In addition, a large variety of other microphysical effects have been identified such as the invigoration of water [Koren et al., 2014] and mixed phase [Rosenfeld et al., 2008a] clouds, and the “cloud-burning effect” [Ackerman et al., 2000; Johnson et al., 2004; Kaufman et al., 2005a].”
