Abstract:

The main objective in the experimental phase of the research was the modification of a photoelectric polarimeter for the measurement of skylight polarization. A single monochromator, acquired for better calibration, was also used for measurements of the optical thickness of the atmosphere. The monochromator was built into a yoke and provided with a simple sun follower which kept the slit of the monochromator constantly illuminated by sun radiation. By scanning through the entire spectrum, the intensity of the sun radiation in all wavelengths was recorded at suitable time intervals. Then, the optical thickness was determined. In the theoretical aspect of the research, the main emphasis was directed towards the evaluation of the effect of large aerosol particle scattering on the polarization of skylight. Another topic of theoretical research was the effect of ozone absorption. The corrections to the sky radiation from a molecular atmosphere due to ozone absorption were computed with the assumption that the ozone in the atmosphere is concentrated at the top of the atmosphere. Lastly, the computations of the effect of sea surface reflection on skylight were performed. Author
