The contents of this thesis describes the design, modification and testing of a differential absorption laser lidar system for the determination of ambient levels of sulphur dioxide in suburban land agricultural environments. Chapter 1 discusses the origins of atmospheric sulphur dioxide pollution and its determination by conventional techniques. The principles of the differential absorption technique are presented in Chapter 2. Chapter 3 presents an extensive error analysis while Chapter 4 describes the instrumental design and the system modifications. The computer programs (both control and data processing) are discussed in Chapter 5. The results of preliminary testing and the performance of the system as a tool for measuring atmospheric S02 are presented in Chapters 6 and 7 respectively. Suggestions for the future and conclusions are presented in Chapter 8. Appendices I - V contain the electronic circuit descriptions and the computer program flow charts.
