Title: CESM run f.c54125clm2.FXHIST.f19_f19.WX.001 data Description: Output are from the CESM2(WACCM-X 2.0). These are results from a free running historical simulation. The model has a horizontal resolution of 1.9˚ latitude by 2.5˚ longitude. This simulation followed the “REFC1D” protocol of the Chemistry Climate Model Initiative [Eyring et al., 2013] for the specification of time-dependent greenhouse gases and ozone depleting substances. Data are provided for evaluation/validation purposes. Please contact marsh@ucar.edu for terms of use. Eyring et al.
