Transmission of 2.0 to 3.4 Micron Infrared Radiation in Ice Fog

Abstract

Limited measurements are made of the transmission of infrared radiation (2.00- to 3.40-micron wavelengths) through ice fog. The experimental results are compared with the spectral transmission predicted by Mie theory for ice spheres and for water fog. The experimental measurements of attenuation by ice fog tend to agree, within the experimental error expected, with values predicted by Mie theory for ice spheres. The present studies are adversely affected by the limited state of the art making accurate measurements of ice fog concentration, and by inadequate control of environmental CO2.
