Abstract

Numerical models are widely used to study the complex phenomenon of air pollution. Nevertheless, their predictions should be compared with range- and time-resolved measurements. In this paper, we suggest LISA (Lidar with Integrated Spectroscopy and Anemometry), a laser radar able to simultaneously retrieve the profiles of aerosol loads, wind vectors, and trace gases. Six beams are emitted in the atmosphere: two are slanting and four are vertical. The beam propagation at different wavelengths gives information on the aerosol load. The wind vector is reconstructed from its components along the three beam directions. The concentration of a trace gas is obtained by differential absorption.
