A mobile Lidar system, mounted in a van, was used to depict the temporal and spatial variations of the mixing depth over the Los Angeles Basin, during the LARPP field tests in the fall of 1973. Lidar profiles are interpreted and compared to vertical temperature and moisture profiles measured by helicopter and standard meteorological sounding techniques. Lidar echo anomalies are classified into mixing layer height or significant levels based on backscatter slop evaluation. The qualitative aspects of each backscatter signature are used in describing the nature and altitude of inversion bases, moisture layers, stratus and fog layers.
