Effect of Aerosol Composition on Cloud Droplet Size Distribution: A Numerical Study
Publisher: American Meteorological Society
Abstract: Numerical computations have been performed to study the effect on the characteristics of a condensationally produced droplet size distribution of a variability in the kind and fraction of soluble material among atmospheric ...
Approximation Formulas to Calculate Infrared Extinction by an Aerosol Having a Junge Size Distribution
Publisher: American Meteorological Society
Abstract: The exact Mie curves for the extinction efficiency factor Qe as a function of the normalized size parameter ?=2α(n?1) are approximated by eight continuous linear segments. These linear approximations for Qe are used to ...
Angular Truncation Error of the Integrating Nephelometer in the Fog Droplet Size Range
Publisher: American Meteorological Society
Abstract: Integrating nephelometers have an inherent error, known as the angular truncation error, which arises from the fact that they integrate scattered light intensity over a truncated angular range from ?1 > 0° to ?2 < 180°. ...
Dependence of the Supersaturation Spectrum of CCN on Aerosol Size Distribution and Composition
Publisher: American Meteorological Society
Abstract: Simultaneous measurements of aerosol size distribution and the supersaturation spectrum of cloud condensation nuclei (CCN) made at the Second International Workshop on Condensation and Ice Nuclei are used to investigate ...
A Numerical Model of the Formation of Droplet Spectra in Advection Fogs at Sea and Its Applicability to Fogs off Nova Scotia
Publisher: American Meteorological Society
Abstract: A one-dimensional numerical model of the formation and evolution of droplet spectra during the early stage of formation of advection fogs at sea is described. The model computes the evolution of a specified population of ...
Approximation Formulas for the Equilibrium Size of an Aerosol Particle as a Function of Its Dry Size and Composition and the Ambient Relative Humidity
Publisher: American Meteorological Society
Abstract: Approximations to the exact equations describing the variation with relative humidity of the equilibrium size of aqueous solution droplets are developed. For relative humidities between 81 and 99.5%, and for droplets formed ...
