Dispersion of Cloud Droplet Size Distributions, Cloud Parameterizations and Indirect Aerosol Effects
Most studies of the effect of aerosols on cloud radiative properties have considered only changes in the cloud droplet concentration, neglecting changes in the spectral shape of the cloud droplet size distribution. However, it has been shown that that the spectral dispersion of the cloud droplet size distribution (defined as the ratio of the standard deviation to the mean radius of the droplet ...

متن کاملParameterization of Cloud Droplet Effective Radius: Effects of Spectral Dispersion and Skewness of Cloud Droplet Size Distributions
Effective radius re (defined as the ratio of the third to the second moment of a droplet size distribution) is one of the crucial variables that determine the radiative properties of liquid water clouds (Hansen and Travis 1974). The inclusion and parameterization of re in climate models has proven to be critical for assessing global climate change (Slingo 1990; Dandin et al. 1997). There has be...
متن کاملTesting Cloud Microphysics Parameterizations in NCAR CAM5 with ISDAC and M-PACE Observations
[1] Arctic clouds simulated by the National Center for Atmospheric Research (NCAR) Community Atmospheric Model version 5 (CAM5) are evaluated with observations from the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Indirect and Semi-Direct Aerosol Campaign (ISDAC) and Mixed-Phase Arctic Cloud Experiment (M-PACE), which were conducted at its North Slope of Alaska site i...
متن کاملEffects of Spectral Dispersion of Cloud Droplet Size Distributions on Radiative Properties of Clouds and Dispersion Forcing
where L is the liquid water content, and ρw is the density of water. In effect, these studies implicitly assume the only effect of aerosols on cloud microphysical properties is to increase N, and re can be parameterized by Eq. (1) for monodisperse droplet size distributions. Eq. (1) has also been used in the parameterization of re. However, available data suggests the spectral shape of the clou...
