This data set supports the analysis presented in the manuscript: “Labrador Sea freshening linked to Beaufort Gyre freshwater release” (LA-UR-20-20936), which is under review for publication by Nature Communications. The model output is from a 186-year long simulation with the E3SMv0-HiLAT code that was described in the technical report: “An eddy-permitting ocean-sea ice general circulation model (E3SMv0-HiLAT03): Description and evaluation” (LA-UR-19-25177; doi:10.2172/1542803), by Zhang et al. The ocean and sea ice components are active, and their grid is configured with a nominal 0.3 degree horizontal resolution. The model is forced by an atmospheric data set that represents the atmospheric state from 1948 through 2009, and is repeated for 3 cycles. # --- # Data description # Fri Jul 24 16:55:12 MDT 2020 # Contacts: Jiaxu Zhang ([e-mail]) and Wilbert Weijer ([e-mail]) # --- Simulation length: 186 years Simulation machine: LANL HPC facility, on Grizzly Case name: t32_GIAF_woa13rest_deepenNares_Griz Time range: 012101-018612 (corresponding to Jan 1948 to Dec 2009) Grid file: gridFile/tx0.3v2_grid.nc In the post-processed files: pop = ocean output from POP2 mon = monthly ann = annual mean clim = monthly climatology ltm = long-term annual mean dec = decadal mean YYYYMM-YYYYMM = time range FastRel = Fast release case, corresponding to the 016001-017212 period FastAcc = Fast accumulation case, corresponding to the 017301-018512 period NH = data only contain the Northern Hemisphere Similarly, there are files for "BG" (Beaufort Gyre), "Davis_Strait", "Fram_Strait", "Labrador_Sea", "Labrador_Sea_Outflow", "Lancaster_Sound", and "Nares_Strait". These regions are illustrated in Figure 1 of the manuscript. Variable names: SALT = salinity UES = East flux of SALT UVEL = Zonal Velocity VNS = North flux of SALT VVEL = Meridional velocity DYE01 = dye tracer that tags the Beaufort Gyre freshwater (from surface to the reference salinity of 34.6) DSALT01 = salt tracer that tags the Beaufort Gyre salinity (from ...
