Advanced Two-Moment Bulk Microphysics for Global Models. Part II: Global Model Solutions and Aerosol–Cloud Interactions* (2015, methodology): “Comparisons to the simulations are difficult due to cloud-top gradients in drop sizes, so we also use in situ ranges of drop size for clean (C) and polluted (P) conditions [see Gettelman et al. (2008) for details].”
An improved representation of the raindrop size distribution for single‐moment microphysics schemes (2012, background): “, 2005) or an exponential distribution (Lin et al., 1983; Rutledge and Hobbs, 1983; Fowler et al., 1996; Wilson and Ballard, 1999; Seifert and Beheng, 2006; Morrison and Gettelman, 2008; Thompson et al., 2008).”
Spatial variability of liquid cloud and rain: observations and microphysical effects (2014, methodology): “Morrison and Gettelman (2008) formulated their microphysics scheme to account for subgrid variability in the calculation of autoconversion and accretion rates; however, they only considered variability of liquid water content, not rainwater content, and had no method of evaluating what the…”
Different contact angle distributions for heterogeneous ice nucleation in the Community Atmospheric Model version 5 (2014, methodology): “CAM5 152 CAM5 includes a two-moment stratiform cloud microphysics scheme (Morrison 153 and Gettelman 2008 (MG08); Gettelman et al., 2008, 2010).”

Toward a Minimal Representation of Aerosols in Climate Models: Comparative Decomposition of Aerosol Direct, Semidirect, and Indirect Radiative Forcing (2012, unknown): “Stratiform cloud microphysics predicts number and mass mixing ratios of droplets and ice crystals and diagnoses number and mass mixing ratios of rain and snow as described by Liu et al. (2007), Morrison and Gettelman (2008), and Gettelman et al. (2008, 2010).”
Are climate model simulations of clouds improving? An evaluation using the ISCCP simulator (2012, background): “In the CAM, the new microphysics is directly responsible for a substantial reduction in liquid water path over middle-latitudes that contributes to its reduction of optically thick clouds [see Figure 12f of Gettelman et al., 2008].”
Climate impacts of ice nucleation (2012, methodology): “CAM5 has a 2-moment cloudmicrophysics scheme [Morrison et al., 2005;Gettelman et al., 2008], coupled to aModal AerosolModel with 3 modes [Liu et al., 2012a].”
Constraining cloud droplet number concentration in GCMs suppresses the aerosol indirect effect (2009, methodology): “Simulations are also shown for NCAR CAM3 with a different two-moment microphysics scheme by Gettelman et al. [2008] , and a different aerosol model (the MOZART Bulk Aerosol Model (BAM) [Tie et al., 2005]), but a similar formulation of droplet activation [Abdul-Razzak and Ghan, 2000]; and for CAM-Os”
