| Abstract: | The influence of the aerosol component on the total transmission of sounding IR radiation is analyzed. The emissions of both
industrial and natural origins into the atmosphere were regarded as the medium. It is noted that, in studying the radiative
transport through gas-aerosol mixtures, it is necessary to take into account both molecular absorption and scattering from
aerosol particles. It is shown that there are certain boundary values of the microphysical parameters of aerosol where it
is sufficient to take into account only one of the above-mentioned factors of radiation extinction. The quantitative values
of the parameters of an aerosol medium, on the basis of which the solution of the transport equation can be significantly
simplified, are given. |
