A brief survey is presented of the available techniques of remote
environmental control over the air space condition. The paper demonstrates
that the most acceptable method for operative gas composition monitoring
in the near-earth atmospheric layers is one of spontaneous combination
scattering (SCS), while the traditional aerosol component lidar analytic
techniques are largely erroneous. A conclusion is made about the lidar
holographic techniques. A scheme is proposed of a gas-aerosol polarization
holographic lidar, in which the air gas composition is controlled, using
the SCS method, while aerosols are studied by analyzing the aerosol
particle registered polarization holograms in atmospheric cross-sections
along the probing path.
