Studies of Electro-Optical Attenuation in the Vicinity of Cloud Base
Abstract
Field measurements of atmospheric transmission in the 10.6 micron wavelength, the 3-5 micron and the 8-12 micron spectral regions over several seasons of the year have been conducted. EO weapon system designers must design for atmospheric effects predicted by these models. This research helps make improvements to the accuracy required. Field measurements were carried out under various atmospheric conditions including those which affect molecular absorption most. These measurements included the appropriate meteorological and optical parameters. Results of the measurements were used to improve empirically the tansmission models and to develop theoretical models for the cloud base physics. Previous efforts by the principal investigator have provided some improvements to the AF Geophysics Laboratory's transmission models and to the British Ministry of Defence's sensor development program. This research effort enhances understanding of absorption of electromagnetic radiation in the atmospheric windows by pre-cloud aerosols and by molecular action. Keywords include: Clouds, Visibility, Electro-Optics, Atmospheric attenuation.
