The character of aerosol absorption in the short-wave spectral region
Abstract
Spectroscopic analysis of fractional aerosol samples shows that the poorly selective character of absorption of atmospheric aerosol is due mainly to the presence of a subfraction formed by soot particles in the 0.002-0.05 micron size range. A method is proposed for determining soot particle concentration based on the spectral dependence of the extinction coefficient in the near infrared. The specific volume of the soot fraction in the atmosphere is estimated to be sufficient for soot to play an important role in the radiation balance of the earth's atmosphere.
