The annual mean global forcing data used in the LC18 paper, based on the best estimates provided in the IPCC AR5 WG1 report, but incorporating recent revisions to greenhouse gas forcing and to post-1990 ozone and aerosol forcing estimates and extended to 2016,  are available here.

All the data files required to reproduce the LC18 results are available within a zip archive, here. These include data for forcing (AR5_Forc.new.csv and AR5_Forc.range.new.csv), planetary heat content (AR5_HC.new.csv) and global surface temperature (HadCRUT4_ensemble.zip, C&W_ensemble.txt and C&W_mean&uncertainty.txt) estimates and uncertainties. The archive also includes estimated ECS and ECShist/ICS values for 31 CMIP5 models (ECStoICS.csv and, saved in native R format, ECStoICS.2_50.Rd).
