Paper Abstract

Knowledge of the aerosol extinction coefficient at infrared wavelengths is necessary for predicting the performance of electro-optical systems such as thermal imagers. Recently, Gerber Scientific Inc. has developed an instrument that makes a local measurement of the aerosol extinction coefficient at a wavelength of 10.6 micrometers . It exploits the strong correlation observed between visible light forward scattered between 0 and 3.6 degree(s) and the infrared extinction coefficient. We report field measurements made with this instrument in advection fog conditions and compare the results with transmissometer measurements of extinction in the 10 - 12 micrometers band.
