Abstract

Keywords

The study tested a two-component cloud containing an

aerosol and gas component, which is necessary to identify

by spectroradiometric method. We analyzed the joint

disturbing action on identification of aerosol radiation

scattering and the transmission spectrum saturation out-

side of the characteristic absorption lines. We obtained

analytical solutions for specific equations of the passive

cloud location in the infrared wavelength range. The study

shows that each equation can have two solutions. The

solutions give the minimum and maximum concentrations

of the gaseous component, when it is possible to identify it

in the presence of the available aerosol concentrations. We

obtained an asymptotic solution corresponding to the case

when at the concentration of gas components there occurs

saturation of only characteristic absorption lines. The

solution shows the limit value of the aerosol concentration,

when it is possible to identify the gas component for the

existing signal/noise ratio of the used spectroradiometer

Emergency emission, identification

of dangerous substance, gas-aerosol

cloud, absorption spectrum, spectro-

radiometer
