Considerations in the Optical Characterization of the Atmosphere.
Abstract
The US Army uses various types of electro-optical devices involving wavelengths from the visible to the near infrared. The performance of these sensors can be adversely affected by turbid atmospheres, especially those containing fog and haze. This report provides a brief review of the characteristics of fogs and hazes and offers a few recommendations on fog and haze measurements. In particular, attempts are made to answer such questions as: (1) whether the fog and haze characteristics found in some United States localities are comparable to those in certain places in West Germany, (2) whether the present standard meteorological measurements made at weather stations are suitable for determining fog optical properties, (3) whether the current fog numerical modeling would be relevant to field operations, and (4) what basic measurements are needed to describe adquately the foggy and hazy environments. Finally, an example of fog and haze measurements conducted on the campus of the State University of New York at Albany is briefly described. (Author)
