Ground-Based Ultraviolet Differential Absorption Lidar (DIAL) System and Measurements

A ground-based Differential Absorption Lidar (DIAL) system was developed by SRI International to measure the atmospheric distribution of several pollutants: SO2, O3, and NO2, gases commonly associated with fossil fuel combustion. Although earlier DIAL research was funded by the National Science Foundation (Grant 1974, 1975), the system described in this paper was developed for the Electric Power Research Institute (EPRI), primarily for use in their Plume Model Validation (PMV) Project (Hilst, 1978). The DIAL system is also being used by utility companies to characterize power plant plume diffusion and is available through SRI to other institutions for similar studies.
