Abstract: A series of low-level tracer experiments conducted in metropolitan St. Louis is described. Values of dispersion parameters, calculated from the tracer data, are related to readily measured or derived meteorological indices ...

Abstract: Elevated pollution layers are observed over Los Angeles with an aircraft equipped with a downward-looking lidar. For the first time, detailed ancillary upper-air kinematic and thermodynamic data were collected simultaneously ...

Abstract: Airborne lidar and supplementary measurements made during a major study of air chemistry in southern California (SCCCAMP 1985) provided a rare opportunity to examine atmospheric boundary-layer structure in a coastal area ...

Abstract: The deployment of a space-based Doppler lidar would provide information that is fundamental to advancing the understanding and prediction of weather and climate. This paper reviews the concepts of wind measurement by Doppler ...
