Abstract
The integrating nephelometer is a convenient instrument for measuring the atmospheric scattering coefficient at a point and may be used to estimate visual range. This paper describes an instrument of this type, developed for use in a study of the relationship between visibility and the concentration of air pollutants. The instrument has a stabilized response and is suitable for automatic operation over long periods. Difficulties of calibration are discussed and the results of a field trial are presented.Keywords
