A modeling study of the response of tropical deep convection to the increase of cloud condensation nuclei concentration: 1. Dynamics and microphysics (2005, background): “3.1. Number Concentrations of Hydrometeors [30] The majority of CCNs are activated at the cloud base, where perhaps the highest supersaturation with respect to water is formed because of both the adiabatic cooling brought by updraft and the lack of disturbance in relative humidity by condensation of”
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].”
A microphysics guide to cirrus clouds – Part 1: Cirrus types (2015, background): “MAID are heterogeneous freezing after Kärcher et al. (2006) and homogeneous freezing after Koop et al. (2000). The heterogeneously freezing ice nuclei (IN) can vary in concentration as well as freezing threshold (RHice, see Fig.”
Ice supersaturation in the ECMWF integrated forecast system (2007, methodology): “The scheme assumes the following: (1) Ice nucleation initiates when the supersaturation locally reaches the threshold specified by Kärcher and Lohmann (2002).”
The Origin of High Ice Crystal Number Densities in Cirrus Clouds (2005, methodology): “This approach is similar to that used by Kärcher and Lohmann (2002); however, we note that the number density calculated by their method is a factor of 2 lower than when the comprehensive microphysical box model is used.”
Aerosol-cloud-precipitation effects over Germany as simulated by a convective-scale numerical weather prediction model (2011, methodology): “Ice nucleation via homogeneous freezing of aqueous solution droplets has recently also been included in the SB microphysics scheme following Kärcher and Lohmann (2002) andKärcher et al. (2006). The competition of heterogeneous and homogeneous ice nucleation is explicitly taken into account, i.”

A microphysics guide to cirrus – Part 2: Climatologies of clouds and humidity from observations (2020, result): “The results of the radiative forcing calculations for the slow- and fast-updraft cirrus are in agreement with investigations from lidar observations reported by Kienast-Sjögren et al. (2016) and Campbell et al. (2016), who observed cirrus with optical depth up to 1 and 3, respectively, and found a d”
