Abstract
In an effort to develop an index of atmospheric turbidity, measurements of the polarization and intensity of light from the sunlit sky were made at the South Pole station, Antarctica. Preliminary data from these measurements at wavelengths of 0.398 and 0.70 μm taken in the vertical plane through the sun are shown and compared with similar data computed for a pure molecular atmosphere overlying a highly reflecting Lambert type surface. The general features of the measured fields are similar to those of the theoretical model, but some consistent discrepancies exist for both the intensity and degree of polarization. It is suggested that the discrepancies are probably due to the fact that a Lambert type surface is not a good approximation to the actual snow surface which exists at the South Pole.
