Measuring Limb Vibrations of Solar Images,r- and lunar-limb images), one of the most important problems is that of establishing quantitative relationships between the statistical characteristics of these fluctuations and the weather conditions on the propagation path. But rather few attempts have been made to establish such relationships.

Light Polarization as an Independent Measure of Atmospheric Purity and Transmittance, it. That the purity, or turbidity, of the atmosphere can be assessed from the polarizing properties of its gaseous and aerosol components is a point that does not meet with any fundamental objections.
