Experimentally Determined Relationship between Extinction and Liquid Water Content.
Abstract
Simultaneous environmental chamber measurements have been made of 10.27 micrometers extinction coefficients and liquid water content of droplet distributions with sizes spanning those of light to heavy fogs. The measurements yield a linear relation which is nearly independent of droplet size distribution, in agreement with recent calculated results and predictions. Liquid water content varied from 0.01 to 3.3 gm/cu m and droplet size distributions with single mode and bimodal differential extinction coefficient curves (extinction coefficient as a function of droplet size) were included. The spectral variation of extinction coefficient between 9.2 micrometers and 10.8 micrometers was also measured. The results are in good agreement with the variation calculated for typical droplet size distributions. (Author)
