Radiative Efficiency and Global Warming Potential of the VOC-exempt Hydrofluorocarbon HFC-43-10mee

Abstract:

HFC-43-10mee (C₅H₂F₁₀) is a substitute to CFC-113, HCFC-141b and methyl chloroform, as well as an alternative to high global warming potential PFCs. Recent observations have shown that the global mean tropospheric abundance of HFC-43-10mee have increased steadily from the 1990’s to reach 0.211 ppt in 2012. To date, the emission of this compound is not regulated. The radiative efficiency (RE) of HFC-43-10mee has recently been re-evaluated at 0.42 W.m^-2 ppb^-1 giving a global warming potential of 1650 for a time horizon of 100 years. However, the initial RE, from which the new values were derived, originates from an unpublished source.

We present the radiative efficiency and global warming potential calculated from laboratory absorption cross-section spectra of a pure vapor of HFC-43-10mee. Acquisitions have been performed in the 550-4000 cm^-1 spectral range using Fourier transform spectroscopy.
