Abstract

The results are compared of investigation of the continuous extinction of visible and IR radiation and the continuum absorption by water vapor in the wavelength range 10.6 micrometer obtained both in field experiment and laboratory chamber. The reliability is confirmed of the results of investigation of the continuous extinction of optical visible and IR radiation that non-linearly depends on absolute humidity of air. The possible reasons are considered leading to the increase of minimum values of the extinction coefficients as absolute humidity increases. One can conclude based on the analysis that the physical reason of the continuous absorption can be absorption by fine aerosol that does not scatter radiation in visible wavelength range.
