CESM data: The Impact of Orbital Precession on Air-Sea CO21 Exchange in the Southern Ocean

CESM output data designed to study the impact of orbital precession on air-sea carbon dioxide flux in the Southern Ocean. These variables contain only the primary model output variables needed to analyze changes in carbon flux. "HighPrec" refers to a simulation set to have maximum seasonal variability in the Southern Hemisphere (the perihelion of Earth's orbit occuring during the SH summer solstice) and maximum eccentricity. "NoPrec" and equilibration both have no eccentricity, and thus no precessional forcing.

1. "CESM.b.T31_g37.Equilibration.0-500.pop.nc" contains the global air-sea carbon dioxide flux for the first 500 years of equilibration.

2. "CESM.b.T31_g37.Equilibration.500-1000.pop.nc" contains the global air-sea carbon dioxide flux for the last 500 years of equilibration.

3. "CESM.b.T31_g37.HighPrec.SO.pop.DIC.nc" contains the Southern Ocean dissolved inorganic carbon for 100 years of HighPrec.

4. "CESM.b.T31_g37.NoPrec.SO.pop.DIC.nc" contains the Southern Ocean dissolved inorganic carbon for 100 years of NoPrec.

5. "CESM.b.T31_g37.NoPrec.SO.pop.nc" contains the ocean temperature, alkalinity, salinity, surface meridional windstress, ice fraction, gas transfer velocity, atmospheric surface pressure, surface pCO2, schmidt number, atmospheric CO2, barotropic streamfunction, and meridional overturning circulation in the Southern Ocean for 100 years of NoPrec.

6. "CESM.b.T31_g37.HighPrec.SO.pop.nc" contains the ocean temperature, alkalinity, salinity, surface meridional windstress, ice fraction, gas transfer velocity, atmospheric surface pressure, surface pCO2, schmidt number, atmospheric CO2, barotropic streamfunction, and meridional overturning circulation in the Southern Ocean for 100 years of HighPrec.

7. "CESM.b.T31_g37.NoPrec.SH.cam.nc" contains the Southern Hemisphere atmospheric temperature, zonal wind, and surface pressure for 100 years of NoPrec.

8. "CESM.b.T31_g37.HighPrec.SH.cam.nc" contains the Southern Hemisphere atmospheric temperature, zonal wind, and surface pressure for 100 years of HighPrec.
