Ground-based Hyperspectral Measurements of the Skylight Polarized Properties

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.
