This thesis describes the design and construction of a differential absorption lidar system for the measurement of ambient levels of sulphur dioxide in agricultural environments. Chapter 1 discusses the effects of sulphur dioxide in the environment together with the most common methods used for analysis. The principles of the lidar technique are presented in Chapter 2. Chapter 3 describes in detail the instrumental system design including the laser transmitter, the telescope receiver, the transient signal digitizer and the microcomputer used for experimental control and data handling. The electronic control circuitry and computer programs are described in Chapters 4 and 5. An account of preliminary experimental results is given in Chapter 6 and the error involved in the measurement of the spatial distribution of sulphur dioxide is investigated in Chapter 7. Appendices I and II give schematic electronic circuit diagrams and computer program flow charts.
