A new two-moment bulk stratiform cloud microphysics scheme in the Community Atmosphere Model, version 3 (CAM3). Part I: Description and numerical tests (2008, background): “Currently, in the new scheme, NIN is not directly related to the aerosol characteristics (e.g., concentration of dust aerosols), although recent work (Khvorostyanov and Curry 2005; Kärcher and Lohmann 2002, 2003; Liu et al. 2007) has begun to address this issue.”
Effect of sulfuric acid coating on heterogeneous ice nucleation by soot aerosol particles (2005, methodology): “Concepts developed for the homogeneous freezing mode [Kärcher and Lohmann, 2002b] have recently been improved and applied for immersion freezing [Kärcher and Lohmann, 2003].”
Climate impacts of ice nucleation (2012, methodology): “[2008] using the ice nucleation parameterization of Kärcher and Lohmann [2002]. If the dust number concentration exceeds 10 L 1 heterogeneous nucleation sets in above a critical relative humidity of 130%.”
Technical Note: On the use of nudging for aerosol–climate model intercomparison studies (2014, background): “Further analysis suggested that this lack of sensitivity to temperature nudging in ECHAM6-HAM2 is possibly attributable to the smaller (compared to CAM5) contribution of homogeneous nucleation to ice crystal number concentration (especially over the tropics), and the weaker sensitivity of ice format”
A parameterization of cirrus cloud formation: Heterogeneous freezing (2003, methodology): “[46] In this work we present a method to formulate simple expressions for Jhet that (1) reduce to the homogeneous rates by Koop et al. [2000a] in the limit of pure liquid particles (as employed in our parameterization for homogeneous freezing) and that (2) are flexible enough to fit any given experi”
The global influence of dust mineralogical composition on heterogeneous ice nucleation in mixed-phase clouds (2008, background): “302 with only four instead of six shortwave spectral bands and without the cirrus scheme by Kärcher and Lohmann (2002) and Lohmann and Kärcher (2002), which gives a slightly different aerosol indirect effect than in Lohmann et al (2007).”
