Paper Abstract

The method and computation algorithm have been developed to assess the effect of scattered light on a signal received by a sun photometer while a cloud optical thickness is measured. The approach provides estimations of impact of scattered light for any receiver field of view with allowance for angular dispersion of sunlight. The accuracy of measurements has been investigated as a function of zenith angle of the Sun, receiver field of view, wavelength, cloud optical thickness. The effect of aerosol scattering is an undercloud layer on the accuracy of cloud optical thickness measurement has also been considered.
