Data in support of "Antarctic Bottom Water sensitivity to spatio-temporal variations in Antarctic meltwater fluxes"

 This data contains the unprocessed output from the five equilibrium  simulations used in the paper "Antarctic Bottom Water sensitivity to spatio-temporal variations in Antarctic meltwater fluxes".  Simulations were run using the ocean and sea-ice components of CESM1, and the atmosphere was data-driven, and based on ERA5 reanalysis from 1958 until 1980. All data is in netcdf, and includes the description of flag values, and units. The five simulations differ in the freshwater flux scheme as described below:

Simulation UNIF - files: ga1.f09_g16.308
Forced with freshwater fluxes from the Antarctic Ice Sheet (AIS), uniformly distributed around the Antarctic coast. Total freshwater flux from AIS: 2075 Gt/yr

Simulation BM - files: ga1.f09_g16.208
Forced with asymmetric zonal freshwater fluxes from the AIS.
Total freshwater flux from AIS: 2075 Gt/yr

Simulation VARI - files: ga1.f09_g16.108
Forced with asymmetric zonal and meridional freshwater fluxes from the AIS. Total freshwater flux from AIS: 2075 Gt/yr

Simulation CV - files: ga1.f09_g16.408
Forced with asymmetric meridional freshwater fluxes from the AIS, to mimic iceberg melting. Total freshwater flux from AIS: 934 Gt/yr

Simulation VARI120% - files: ga1.f09_g16.x18
Same as VARI, but the total freshwater fluxes were increased by 20%. Total freshwater flux from AIS: 2490 Gt/yr
