Abstract : A new lidar technique is proposed for the remote determination of the obscuration effects of natural and man-made aerosols. It is based on the simultaneous measurement of the lidar returns at different fields of view. By rationing these returns, we eliminate the need for a backscatter-to-extinction relation which makes the inversion of the single-scattering lidar measurements subject to uncertainties. A system operating at 1.054 micron and fields of view of 5, 25, 50 and 75 mrad is described. Preliminary results are discussed.
