CESM2 2 degree SSP2-4.5 and SSP5-8.5 Experiments

This dataset runs the 2 degree CESM2 SSP2-4.5 and SSP5-8.5 experiments following the protocol described in: Meinshausen, M., Nicholls, Z. R., Lewis, J., Gidden, M. J., Vogel, E., Freund, M., ... & Wang, R. H. (2020). The shared socioeconomic pathway (SSP) greenhouse gas concentrations and their extensions to 2500. Geoscientific Model Development, 13 (8), 3571-3605, https://doi.org/10.5194/gmd-13-3571-2020, 2020.

Each SSP scenario runs is comprised of 4 experiments: * One simulation spanning 2015-2100 using the SSP protocol which restarted using data from the historical run b.e21.BHIST.f19_g17.CMIP6-historical-2deg.001 at year 2015. * One simulation spanning 2100-2130 which cycles through the forcing of the year 2100 for 30 years. This experiment is meant to create a short climate variability dataset. * One simulation spanning 2100-2300 extending the SSP simulation from the end of 2100. * One simulation spanning 2250-2280 which cycles through the forcing from year 2250.

These simulations can be directly compared to their 1 degree CESM2 counterparts.

See the Documentation tab for a complete list of available variables.

These runs were supported with resources from NSF OPP (#2045075 and #2044965).
