CESM1.2 Ensemble for the Samalas Eruption

This dataset contains model simulation output from CESM1.2 for the 1258 CE Samalas volcanic eruption. The data are organized into two categories: (1) Full-Forcing Experiments (M13C-FF_TS) Simulations spanning January 1256 to December 1260. File naming convention: TS_b.e11.B1850C5CN.f19_g16.LME.Restart.to.1258.#.cam.h0.1256_1260.nc where # denotes the ensemble member number 001-015. (2) Pacemaker Experiments Simulations spanning April 1258 to March 1260, divided into two groups: Cooling Group (prescribed SST cooling applied to specified ocean basins): Atmosphere variable: *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.A.I..cam.h0.1258_1260.nc — Both the tropical Indian Ocean and equatorial Atlantic cooling *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.ATL.cam.h0.1258_1260.nc — Equatorial Atlantic cooling only *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.Indian.cam.h0.1258_1260.nc — Tropical Indian Ocean cooling only Ocean variable: *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.A.I.pop.h.1258_1260.nc — Both the tropical Indian Ocean and equatorial Atlantic cooling *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.ATL.pop.h.1258_1260.nc — Equatorial Atlantic cooling only *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cooling.mme.Indian.pop.h.1258_1260.nc — Tropical Indian Ocean cooling only Climatology Group (climatological SST prescribed as control): Atmosphere variable: *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.ATL.Indian.cam.h0.1258_1260.nc — Both the tropical Indian Ocean and equatorial Atlantic SST nudged to climatology *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.ATL.cam.h0.1258_1260.nc — Equatorial Atlantic SST nudged to climatology only *_merge_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.Indian.cam.h0.1258_1260.nc — Tropical Indian Ocean SST nudged to climatology only Ocean variable: *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.ATL.Indian.pop.h.1258_1260.nc — Both the tropical Indian Ocean and equatorial Atlantic SST nudged to climatology *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.ATL.pop.h.1258_1260.nc — Equatorial Atlantic SST nudged to climatology only *_merge_b.e11.B1850C5CN.f19_g16.LME.April.1258.#.Pacemaker.cli.Indian.pop.h.1258_1260.nc — Tropical Indian Ocean SST nudged to climatology only where * denotes the variable name; # denotes the ensemble member number 001-015.
