SLAB OCEAN SIMULATIONS

Structure of filenames:
[Variable].[Simulation_Name].ts.001-100.ANN.nc

All files contain the annual, 100-year timeseries for a single variable. For analysis, the first 40 years are considered to be the model equilibration period. Years 40-100 are used as the equilibrated signal.

Variables:
TREFHT = 2D Surface Air Temperature
PREC = 2D Convective and Largescale Precipitation Rates

E_2000_CAM5_1850aero = Control simulation, year 2000 conditions in all but anthropogenic aerosols, anthropogenic aerosols at year 1850 values.
E_2000_CAM5_1850aero_BRonly_Jan18 = Brazil-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of Brazil
E_2000_CAM5_1850aero_CHonly_Jan18 = China-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of China
E_2000_CAM5_1850aero_EAonly_Jan18 = East Africa-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of East Africa
E_2000_CAM5_1850aero_EUonly_Jan18 = Europe-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of Western Europe
E_2000_CAM5_1850aero_INonly_Jan18 = India-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of India
E_2000_CAM5_1850aero_NESonly_Jan18 = Indonesia-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of Indonesia
E_2000_CAM5_1850aero_USonly_Jan18 = US-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of the United States
E_2000_CAM5_1850aero_SAonly_Jan18 = South Africa-only perturbation simulation, control simulation conditions, but with fixed aerosol perturbation added within geographic boundaries of South Africa

ATMOSPHERE-ONLY SIMULATIONS

Structure of filenames:
[Variable].[Simulation_Name].ts.001-60.ANN.nc OR
[Variable].[Simulation_Name].mon.001-60.nc

Files contain either the annual, 60-year timeseries ('...ANN.nc') or the monthly, 60-year timeseries ('...mon....nc') for a single variable. For analysis, the first 20 years are considered to be the model equilibration period. Years 20-60 are used as the equilibrated signal.

PREC = 2D Convective and Large-scale Precipitation Rates
PRECL = 2D Large-scale Precipitation Rates
PRECC = 2D Convective Precipitation Rates
FLNT = 2D Net longwave flux at top of model
FLNS = 2D Net longwave flux at the surface
