Laser meter of atmospheric aerosol inhomogeneity properties in visible and ultraviolet spectral bands

The purpose of this study was to describe laser meter of atmospheric aerosol inhomogeneity properties in visible spectral band for the wavelength of 532 nm and in UV spectral band for the eyes safe wavelength of 355 nm. We examine the parameters of laser meter units and describe control flow chart of processing measurement data. We illustrate the findings of the research with the examples of typical laser echo-signal from the atmosphere and spatio-temporal distribution of variability index of back scatter volume coefficient in atmosphere. Measurement data show that average aerosol inhomogeneity size equals ~5 m and variability index reach the value ~3-6% for the wavelength of 532 nm and ~1,2-2,1% for the wavelength of 355 nm.
