Abstract: A parameterization is described for low-level clouds that are characteristic of the Arctic during winter. This parameterization simulates the activation of aerosols, the aggregation/coalescence, and the gravitational ...

Abstract: In support to the development of the Northern Aerosol Regional Climate Model, a single column model with explicit aerosol and cloud microphysics is described. It is designed specifically to investigate cloud?aerosol ...

Abstract: The spectral-difference algorithm of Barker and Marshak for inferring optical depth τ of broken clouds has been shown numerically to be potentially useful. Their method estimates cloud-base reflectance and τ using spectral ...

Abstract: Several observational datasets were used to assess the quality of the radiative characteristics of the Canadian Climate Centre (CCC) second-generation GCM. The GCM data were obtained from the Atmospheric Model Intercomparison ...
