Visible and Infrared Obscuration Effects of Ice Fog

Abstract

Ice fog is a phenomenon which causes severe obscuration effects at visible and infrared wavelengths in areas where there is a source of water vapor and the ambient temperature falls below -30 C. In this report, Mie scattering calculations have been used to simulate ice fog obscurations and to derive relationships between extinction at these wavelengths. the results are used to compare the extent of the obscuration by ice fog at various wavelengths. Visible wavelengths are found to be less obscured than 1.06, 3.5 to 5.0, and 11.5 to 12. 0 micrometers and more obscured than 3.0 and 8 to 11 micrometers.
