Light Pollution in Ultraviolet and Visible Spectrum: Effect on Different Visual Perceptions
Figure 3
The is the aerosol optical thickness at the reference wavelength 500 nm.
One of the most interesting features of this figure is the possibility to extract the portions of sky glow levels in VIS spectral band. The aim is to evaluate the radiative fluxes based on the luminous fluxes that humans can feel as sky glow. The evaluated ratios are measured in lx.W−1.m2.
