Download results for all compounds (Excel file)

This file contains lifetimes, radiative efficiencies (RE), global warming potentials (GWP) and global temperature-change potentials (GTP) for the more than 200 compounds included in Hodnebrog et al. (2013). The GWP values are given for time horizons of 20, 100 and 500 years, while the GTP values are given for time horizons of 20, 50 and 100 years. The compounds are listed with chemical names, formulas, acronyms and CAS numbers.

Simple method for calculating REs and GWPs (Excel file)

The original Pinnock et al. (1995) curve and the Oslo simulation of the Pinnock curve are given here (sheet 2 and 3). The latter curve is given in wavenumber resolutions of both 10 cm-1 and 1 cm-1, and can be used to calculate instantaneous RE when the absorption cross-section of a compound is known. In sheet 1, the RE and GWP 100-yr values can be calculated from the instantaneous RE, lifetime and molar mass of a compound.

References to lifetimes (PDF file)

For the majority of compounds, lifetime estimates have been taken from the 2010 Scientific Assessment of Ozone Depletion from the World Meteorological Organization (WMO, 2010). This PDF document gives references to lifetime estimates for compounds where WMO (2010) has not been used.

References to absorption cross-sections (PDF file)

Tables with references to absorption cross-sections used to calculate the RE for each compound can be found here. The absorption cross-sections come from a variety of sources, including the HITRAN-2008 and GEISA-2011 databases, authors of published papers, and supplementary material to published papers. Experimental absorption cross-sections have been used for the majority of compounds, but for a few compounds theoretical spectra were used because of unavailability of experimental spectra.
