Abstract: The concentration of sulfate ion in precipitated water was examined in instances when the type of cloud and its base temperature were well defined, and the precipitating cloud isolated from continental surface air. The ...

Abstract: A mensuration and description method is proposed that allows objective and simultaneous expression of the physical properties of snow crystals, rime drops, and aerosol particles. It is based on the statistics of Hatch and ...

Abstract: A series of aerosol and meteorological observations have been obtained for the trade wind region, from a meteorological tower on the north shore of Oahu. These observations have been supported by aircraft experiments, and ...

Abstract: Ice crystal precipitation was observed and the crystals replicated, at the South Pole during January and February 1974. The crystals were of columnar form. These columns were hollow or prismatic, and sometimes were in the ...

Abstract: Aerosol number concentrations were measured, using a photoelectric nucleus counter, at three locations in Antarctica. This nucleus counter was of high sensitivity and equipped with a diffusion battery to permit estimation ...

Abstract: Total aerosol concentrations have been observed twice daily at the South Pole since January 1974, using a Pollak photoelectric nucleus counter. The aerosol size distribution has been approximated using the Rich diffuser ...

Abstract: A laboratory model of a breaking wave or whitecap was constructed, and the aerosol produced by it was investigated intensively. Submicron- and even Aitken-sized particles were produced: the presence of salt particles of ...

Abstract: The photoelectric condensation nucleus counter of Pollak with convergent light beam has been compared with an electrical aerosol detector using monodisperse aerosols with particle diameters between 0.025 and 0.15 ?m, ...
