• Global observations of aerosol‐cloud‐precipitation‐climate interactions (2014, background): “…for Environmental Research (HIAPER) Pole-to-Pole (HIPPO) project over the Pacific Ocean, showed that the BC concentrations in themiddle and upper troposphere were overestimated by all models up to an order of magnitude, with an average overestimation by a factor of 5 [Schwarz et al., 2010].”
• 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): “More recently, measurements of BC through laser-induced incandescence have provided powerful insight into the distribution of BC from local to global scales (Schwarz et al. 2010) and on the potential for BC particles to be coated (Schwarz et al. 2008b).”
• Contrasting the direct radiative effect and direct radiative forcing of aerosols (2014, unknown): “Schwarz et al. (2010) show that the AeroCom I models generally overestimate BC (by an average a factor of 5) in remote regions based on comparisons with the HIPPO airborne observations over the Pacific.”
• Enhanced Solar Energy Absorption by Internally-Mixed Black Carbon in Snow Grains (2012, background): “(2011) that improved the 10 simulated atmospheric BC distribution in remote regions like the Arctic, relative to observations (Schwarz et al., 2010).”
• Toward a Minimal Representation of Aerosols in Climate Models: Comparative Decomposition of Aerosol Direct, Semidirect, and Indirect Radiative Forcing (2012, background): “In addition, CAM tends to put a larger fraction of BC in the upper troposphere/lower stratosphere than other models do (Schwarz et al. 2010; Liu et al. 2011), which can increase the direct forcing by BC by 20% (Zarzycki and Bond 2010).”
• Radiative forcing in the ACCMIP historical and future climate simulations (2013, background): “Comparison with remote in situ measurements indicates that most models overestimate BC (Schwarz et al., 2010), suggesting that the oceanic AAOD underestimates may be due to an underestimate of the Southern Hemisphere sources or lifetime of dust.”
• Black carbon vertical profiles strongly affect its radiative forcing uncertainty (2012, background): “Several studies have previously indicated that the vertical transport is one area where the models still differ signifi-cantly (Koffi et al., 2012; Schwarz et al., 2010; Textor et al., 2006, 2007).”
• Investigating cloud absorption effects: Global absorption properties of black carbon, tar balls, and soil dust in clouds and aerosols (2012, methodology): “[54] To examine whether the model overpredicts BC, either in the column average or vertical profile, modeled BC vertical profiles were compared with data between 67 S and 80 N over the Pacific from 1–31 January 2009 from the HIPPO campaign [Schwarz et al., 2010] (Figure 11).”
