S. Pinnock et al., RADIATIVE FORCING OF CLIMATE BY HYDROCHLOROFLUOROCARBONS AND HYDROFLUOROCARBONS, JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES, 100(D11), 1995, pp. 23227-23238
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
