Analysis and quantification of the diversities of aerosol life cycles within AeroCom (2005, unknown): “(2003) MPI HAM Lohmann and Roeckner (1996); Tompkins (2002) Tiedtke (1989) with modification for penetrative convection according to Nordeng (1994) Stier et al.”
A parameterization of cirrus cloud formation: Homogeneous freezing of supercooled aerosols (2002, methodology): “In the European Center for Medium Range Weather Forecast model Hamburg version (ECHAM) GCM, for example, Lohmann et al. [1999] estimated the variances w used in the cloud droplet activation scheme by 0:7 ffiffiffiffiffiffiffiffiffi TKE p ; where TKE is the turbulent kinetic energy.”
A parameterization of cirrus cloud formation: Heterogeneous freezing (2003, methodology): “[20] The physics of ice initiation in cirrus is largely controlled by two distinct timescales [Kärcher and Lohmann, 2002a, 2002b].”
Inclusion of Ice Microphysics in the NCAR Community Atmospheric Model Version 3 (CAM3) (2007, methodology): “Another method to calculate the cloudscale updraft velocity is to use a velocity derived from the turbulent kinetic energy (TKE; Lohmann 2002).”
First interactive simulations of cirrus clouds formed by homogeneous freezing in the ECHAM general circulation model (2002, methodology): “[8] The ECHAM model used in this study is a modified version based on the model by Lohmann et al. [1999a] and Lohmann [2002].”
Global indirect aerosol effects: a review (2004, unknown): “Depending on the fraction of black carbon as contact ice nuclei, the anthropogenic aerosol burden can be reduced between 38% and 58% as compared to the simulation where black carbon does not act as a contact nuclei (Lohmann, 2002a).”
The global influence of dust mineralogical composition on heterogeneous ice nucleation in mixed-phase clouds (2008, methodology): “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).”
Global model simulations of the impact of ocean-going ships on aerosols, clouds, and the radiation budget (2007, methodology): “Activated particles are used as input for a microphysical cloud scheme ( Lohmann et al., 1999; Lohmann, 2002) replacing the original cloud module of the GCM.”
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.”
A Classical-Theory-Based Parameterization of Heterogeneous Ice Nucleation by Mineral Dust, Soot, and Biological Particles in a Global Climate Model (2010, methodology): “Parameterizations that are used in large-scale models are mostly empirical (Lohmann 2002; Lohmann and Diehl 2006; Hoose et al. 2008; Morrison and Gettelman 2008; Phillips et al. 2008; Storelvmo et al. 2008a).”
Cloud microphysics and aerosol indirect effects in the global climate model ECHAM5-HAM (2007, methodology): “In ECHAM4 an empirical relationship between the mean volume radius r v and the effective radius (Moss, pers. comm. and (Lohmann, 2002b)) has been used: r i = 1.61r 3 v + 3.56 × 10 −4 r 6 v (5) where r v is obtained from the cloud ice mixing ratio in the cloudy part of the grid box q i and the ice…”
Mesoscale modeling of springtime Arctic mixed-phase stratiform clouds using a new two-moment bulk microphysics scheme (2005, background): “Lohmann (2002b) found that increasing the number of contact nuclei led to more rapid glaciation, increased amounts of ice, and increased precipitation in a general circulation model study.”
