Infrared optical constants of aerosols at some locations.

ABSTRACT

Spectra of absorption indices and data on gross chemical composition for two size classes of water soluble and dust fractions of high-volume aerosol samples are presented for several locations (mainly Bedford, Massachusetts; Meppen in Germany; Riverside and San Nicolas Island in California and some maritime locations). The absorption data were obtained by the KBr-pressed disk method. It has been found that re-grinding of the pellets increases the absorption by salt samples considerably.
