Relationships between Ir Extinction, Absorption, and Liquid Water Content of Fogs.
Abstract
It is well known that atmospheric fog and haze particles degrade the performance of DOD electro-optical sensors. A quantitative assessment of these effects unfortunately requires knowledge of droplet size distributions, which generally have complex spacial and temporal variations. The problem would be simplified considerably if estimates of the radiative properties of fog and haze particles could be made without detailed knowledge of their size distributions. In this report, an attempt is made to find relationships between the radiative properties of fogs and hazes (in particular the volume extinction and absorption coefficients) and their liquid water content, that are relatively independent on droplet size distribution.
