Infrared Absorptivity of Ice Ih and Its Atmospheric Emission.
Abstract
Quantitative spectra of atmospheric ice Ih are presented for 3.4 to 15 micrometers, and absorptivity coefficients for ice and liquid water at 8 to 14 micrometers are presented and compared. A modified equation modeling contributions of water in the vapor, liquid, and ice Ih phases to total atmospheric emission is presented. In the infrared 'continuum' at 8 to 14 micrometers, traces of either ice Ih or liquid water aerosol can affect radiance measurements more strongly than large concentrations of the vapor. Whereas water vapor has been studied extensively as a source of infrared emission in the atmosphere, liquid water and ice contributions have been appreciated only recently. (Author)
