Abstract: Simultaneous measurements have been made of the concentrations of cloud condensation nuclei, sodium-containing particles, Aitken nuclei, and the magnitude of the light scattering coefficient of the air, for a period of two ...

Abstract: The original automatic cloud condensation nucleus counter developed by Radke and Hobbs has been improved by reducing the size and weight of the instrument and increasing the sampling rate. In comparison tests with four ...

Abstract: A cloud condensation nuclei counter has been developed in which the concentration of water droplets which form on cloud condensation nuclei in a large thermal diffusion chamber is determined electronically by measuring the ...

Abstract: An airborne instrument which provides real-time measurements of the concentrations of ice particles in excess of a certain size has been developed. The instrument utilizes a beam of polarized light and the birefringent ...

Abstract: Since the Ptarmigan flights in the 1950s, the springtime visibility reduction in the Arctic has been identified with pollution aerosol. However, observed values of the dry aerosol extinction coefficient are too small to ...

Abstract: Anthropogenic aerosols are composed of a variety of aerosol types and components including water-soluble inorganic species (e.g., sulfate, nitrate, ammonium), condensed organic species, elemental or black carbon, and mineral ...
