Abstract:

The results of numerical statistical simulations of experiments of the cloud layer ground-based sensing by the terahertz linearly polarized radiation at few wavelengths from the atmospheric transparency windows are presented in the paper. Liquid droplet size distributions, summarized results of many years field measurements in the midlatitudes of the Earth and the distributions obtained by aircraft experiments off Great Britain coast are used in the scattering layer models. The models of the scattering medium take into account the vertical stratification of the water vapor concentration in the atmosphere and the differences in the cloud layer microstructure at the top and base.

Keywords:

cloud droplet size distribution, terahertz radiation, remote sensing, polarization, Monte Carlo method, local estimate
