This contains the CESM forcing files and ocean model output used in Chiang
J.C.H, K. Tokos, S.-Y. Lee, and K. Matsumoto, Contrasting impacts of the
South Pacific Split Jet and the Southern Annular Mode modulation on
Southern Ocean circulation and biogeochemistry. In revision
for Paleoceanography, Oct 2017.
See Chiang et al. (2017) for details.
1. Forcing files There are four tar files that contain the forcing fields
for each of the four simulations done: SJ_weak_POP2_forcing.tar - weak
Split Jet; SJ_strong_POP2_forcing.tar - strong Split
Jet; SAM_negative_POP2_forcing.tar - negative
SAM; SAM_positive_POP2_forcing.tar - positive SAM The model used is
the Community Earth System Model (CESM) 1.2.2, using the
compset “2000_DATM%NYF_SLND_CICE_POP2_DROF%NYF_SGLC_SWAV”. It includes
prognostic ocean (POP2) and sea ice (CICE) modules, but with a prescribed
‘data’ atmosphere (DATM) and ‘data’ runoff (DROF). Details of the model,
and code, can be found here: http://www2.cesm.ucar.edu Each tar file
contains 3 files, replacing the standard 'Normal year' forcing
files used (nyf.giss.T62.051007.nc; nyf.gxgxs.T62.051007.nc;
and nyf.ncep.T62.050923.nc) 2. Model output There are four NETCDF
files that contain the annual average of the last 20 years of 600-year
simulations using the forcing fields above. The data was regridded from
the gx1v6 horizontal resolution to a uniform 1x1 degree resolution, using
the netcdf NCO's 'ncremap' function.
SAM_negative_20yrclim.nc - negative SAM
simulation; SAM_positive_20yrclim.nc - positive SAM simulation;
SJ_weak_20yrclim.nc - weak Split Jet simulation; and SJ_strong_20yrclim.nc
- strong Split Jet simulation See the master field
list http://www.cesm.ucar.edu/models/atm-cam/docs/cam2.0/UsersGuide/UG-45.html#TABLE2_7 for description of each output variable
