Abstract :
Measurement of polarized properties of the skylight from the ground is one of an effective means of investigating the optical and physical parameters. A new system to measure the natural skylight polarized radiance distribution has been developed. The system is based on the field spectrometer Analytical Spectral Devices (ASD) with a dichroic linear polarizing filter. With this system sequences of radiance data were obtained which can be determined the linear polarization components of the skylight. The ground-based measurements are compared with simulations based on semi-empirical Rayleigh model.
