Paper I: the measurement of plume rise and dispersion at tilbury power station

Abstract A description is given of the system of instrumentation which has been installed at Tilbury Power Station to record continuously: 1. (a) surface sulphur dioxide concentration at distances from 1 km to 13 km downwind of a 360 MW power station with two 100 m stacks 2. (b) The rise of the plume 3. (c) Lapse rate, humidity, turbulence, wind speed and wind direction up to 187 m above ground level. The paper is intended as a common introduction to a number of papers which will present the experimental results.
