The Effects of Relative Humidity on Atmospheric Aerosol Extinction in the 3-5 Micrometers and 8-15 Micrometers Spectral Regions,

Abstract

The variation of the infrared aerosol extinction coefficient as a function of relative humidity is studied. This is based on a two component particle distribution model. The aerosol extinction coefficient increases by a factor of more than 10 throughout the 3-5 and 8-15 micrometers spectral regions as the relative humidity increases from 0.5 to 0.99. For high relative humidities, a region of lower extinction around 10-11 micrometers is noticed. (Author)
