Abstract
We measure infrared absorption spectra of 18 hydrochlorofluorocarbons and hydrofluorocarbons, seven of which do not yet appear in the litera ture. The spectra are used in a narrowband model of the terrestrial in frared radiation to calculate radiative forcing and global warming pot entials. We investigate the sensitivity of the radiative forcing to th e absorption spectrum temperature dependence, halocarbon vertical prof ile, stratospheric adjustment, cloudiness, spectral overlap, and latit ude, and we make some recommendations for the reporting of radiative f orcings that would help to resolve discrepancies between assessments. We investigate simple methods of estimating instantaneous radiative fo rcing directly from a molecule's absorption spectrum and we present a new method that agrees to within 0.3% with our narrowband model result s.
