Abstract

Absolute infrared photoabsorption cross-sections have been measured over the range 600–1500 cm−1 for the powerful greenhouse gas SF5CF3 at high resolution (0.03 cm-1) and at temperatures between 203 and 298 K. Our data indicate that the integrated absorption intensity shows a weak negative dependence on temperature. It is concluded therefore that previous calculations of radiative forcings and global warming potentials based on room-temperature data are reasonable estimates for the atmosphere, but may be low by a few percent.
