On the behaviour of the atmospheric scattering coefficient shortly before a change in airmass
Abstract From 24 November 1983 to 6 May 1984 the aerosol scattering coefficient was measured continuously at Vienna, Austria. Before a change in air mass the variation of this coefficient followed patterns highly characteristic of the type of change. Approximately 3 h before the passage of a front the scattering coefficient increased by a factor of two or more without a corresponding increase of relative humidity and then dropped to or below its previous value. A slow change in the weather situation accompanied by slowly veering winds gave wild variations of the scattering coefficient according to different plumes passing the measuring site. When this change was completed the scattering coefficient returned to its normal pattern.
