Reconstruction of aerosol microphysical properties sometimes is like an art. With the lack of complete information about EM wave scattering on particles, we have to use some approximations. This is especially important in lidar sounding of the atmosphere. Aerosol scattering properties depends on complex refractive index of scattering medium, incident wavelengths, aerosol size distribution, scattering angle. On practice we only have backscattering signal at some wavelengths at backscattering. In this paper, we consider a new approach to processing active remote sensing data, which allows us to estimate the concentration of particles, as well as to estimate the most likely values of the complex refractive index. This approach is based on the further development of the Umov effect.
In this article we present the numerical study of aerosol condensation growth. Such events occurs when relative humidity exceeds 75%. We found that depolarization ratio does not uniquely determine the degree of sphericity of aerosol particles.
In this paper we present a new measurement tool - polarimeter, based on video matrix. Polarimetric measure- ments are usefull, for example, when monitoring water areas pollutions and atmosphere constituents. New device is small enough to mount on unmanned aircraft vehicles (quadrocopters) and stationary platforms. Device and corresponding software turns it into real-time monitoring system, that helps to solve some research problems.
