title: Extinction of CO2 laser radiation by fog and rain.
abstract: Results of extinction measurements of CO(2) laser radiation by fog and rain are discussed. Experimental results obtained in fog with extinction ranging from 1 to 72 dB/km and in rain with extinction ranging from 1.7 to 17 dB/km are reported. Extinction by fog is supported by an extensive particle size data base. Calculations of extinction obtained from size distributions yielded extinction in excess of 290 dB/km. Measurements show that transmission losses in dense fog can easily be 6 orders of magnitude greater than losses in heavy rain.
