%0 Journal Article %T Method for Estimation of Aerosol Parameters Based on Ground Based Atmospheric Polarization Irradiance Measurements %A Kohei Arai %J International Journal of Advanced Computer Sciences and Applications %D 2013 %I The Science and Information (SAI) Organization %X Method for aerosol refractive index estimation with ground based polarization measurement data is proposed. The proposed method uses a dependency of refractive index on p and s polarized down welling solar diffuse irradiance. It is much easy to measure p and s polarized irradiance on the ground with a portable measuring instrument rather than solar direct, diffuse and aureole measurements. Through theoretical and simulation studies, it is found that the proposed method show a good estimation accuracy of refractive index using measured down welling p and s polarized irradiance data with a measuring instrument pointing to the direction which is perpendicular to the sun in the principal plane. Field experimental results also show a validity of the proposed method in comparison to the estimated results from the conventional method with solar direct, diffuse and aureole measurement data. %K Degree of Polarization %K aerosol refractive index %K size distribution %U http://www.thesai.org/Downloads/Volume4No2/Paper_34-Method_for_Estimation_of_Aerosol_Parameters_Based_on_Ground_Based_Atmospheric_Polarization_Irradiance_Measurements.pdf
