GLORIES ON VENUS: EXISTENCE CONDITIONS AND THE EFFECT OF SIZE AND SHAPE VARIATIONS

Abstract

We have studied in detail the question of the existence of glory with different parameters of scattering particles. We have found that prominent glory can exist at more wide range of size variations, than is believed to be before. Spherical sulphuric acid droplet having size R = 1.05 µm could produce glory even at size variation νef f ≈ 0.34µm at wavelength 0.513 µm, as well as at 0.365 and 0.965 µm this variation is even wider. Moreover, we studied the influence of shape variation on glory formation. We found that nonspherical particles can produce glory too, and determine the range of appropriate nonsphericity of Venusian atmosphere particles.
