Effective Refractive Indices of Water and Sulfate Drops Containing Absorbing Inclusions
Publisher: American Meteorological Society
Abstract: In this study the range of visible refractive indices and single-scattering albedos that can be obtained using various mean field formulations for mixtures of two components, where one component absorbs in the visible, is ...
Another Look at the Influence of Absorbing Aerosols in Drops on Cloud Absorption: Large Aerosols
Publisher: American Meteorological Society
Abstract: Since as early as 1969, solar absorbing aerosols inside of cloud drops have been suggested to influence cloud radiative properties. The absorbing aerosols were invoked to help explain two ?anomalies?: 1) the maximum visible ...
The Attenuation of Sunlight by High-Latitude Clouds: Spectral Dependence and Its Physical Mechanisms
Publisher: American Meteorological Society
Abstract: Measurements of the ground-level solar irradiance from Palmer Station, Antarctica, and Ushuaia, Argentina, reveal a systematic wavelength dependence in the attenuation provided by cloudy skies. As wavelength increases from ...
How Different Calculations of the Refractive Index Affect Estimates of the Radiative Forcing Efficiency of Ammonium Sulfate Aerosols
Publisher: American Meteorological Society
Abstract: alculations of the radiative properties of hydrated ammonium sulfate (AS) aerosols often employ the conventional volume mixing rule, in which the refractive indices of AS and water are linearly averaged, weighted by their ...
