The present knowledge of the atmospheric aerosols is summarized briefly with respect to geographical distribution, time variations, optical properties, chemical nature, and natural and artificial sources. The measurement techniques for determining aerosol properties are sumarized with the limitations and results from each. The problems resulting from variations in refractive index, shape, composition, volatile constituents, relative humidity and time from collection until measurement are described. Needed measurements on atmospheric aerosols are outlined with some of the latest methods for obtaining them, including the needs and goals of some world-wide programs.
