Abstract : To learn more about potential fog condensation nuclei content, 71 Anderson sampler particulate samples from the White Sands Missile Range, New Mexico area were examined. During a portion of the sampling period, from September to December, 1969, the Royco light scattering counter was employed simultaneously. Sulfates appeared to account for most of the soluble and thus potential condensation nuclei. Moisture was an important positive influence on the number of these particles; wind speed decreased their number. In general, the number of large and giant particles remained constant throughout the day. Daytime fluctuations were attributed to incursions of foreign air masses or to rain washout. It is concluded that the sulfate ion is sufficiently abundant in this and other nonurban areas to be a dominant constituent in cloud and fog condensation nuclei. (Author)
