Abstract:Measurements of the maximum hourly average concentration of sulphur dioxide at Tilbury, grouped according to wind speed and vertical temperature profile, are compared with values calculated from an expression developed by Moore (1972). It is concluded that the expression can be used to predict Tilbury concentrations without change in the parameters derived from North-fleet data. The expression still applies, even in conditions when chimney down-wash has been observed, indicating that the fraction of the plume material involved in down-wash is fairly small.
