Description
This dataset contains the underlying data for the manuscript Brown et al., Arctic Ocean freshwater dynamics: transient response to increasing river runoff and precipitation, submitted to JGR-Oceans
-----------------------------------
Descriptors in the filenames, shown below as *, correspond to the various simulations, as follows:
Simulations forced with JRA-25 reanalysis data:
AR: Unperturbed control simulation
B1: Simulation involving a step change in river runoff of -30%
C1: Simulation involving a step change in river runoff of +30%
B7: Simulation involving a step change in precipitation of -30%
C8: Simulation involving a step change in precipitation of +30%
Simulations forced with the CORE-II climatology:
AR_CORE: Unperturbed control simulation
P-30_CORE: Simulation involving a step change in precipitation of -30%
P+30_CORE: Simulation involving a step change in precipitation of +30%
-----------------------------------
The files named as fwvolume_Sref35_*.nc contain the variables:
freshwater: horizontally-integrated liquid freshwater volume in m^3
freshwater_pos: as before, but including only positive values in the integration
h_f: basin-mean freshwater height in m
h_f_pos: as before, but including only positive values in the integration
The reference salinity used in each case is 35.
-----------------------------------
The files named as freshwater_h_f_*.nc contain horizontally-gridded, depth-integrated liquid freshwater heights in m. The integration is made to a depth of 276.68m.
h_f_34p8: freshwater height, using a reference salinity of 34.8
h_f_34p8_pos: as before, but including only positive values in the integration
h_f_35: freshwater height, using a reference salinity of 35
h_f_35_pos: as before, but including only positive values in the integration
The grid for these files is grid.nc
-----------------------------------
The files named as fluxes_ed3_*.nc contain strait-integrated volume fluxes (in m^3 s^-1) into and out of the Arctic domain:
f: liquid volume flux
fw: freshwater, with variables numbered 1 using a reference salinity of 34.8 and those numbered 2 using a reference salinity of 35
ice: sea ice volume flux
The first dimension, ngate, of the variables indicates the strait:
1) Fram Strait
2) Barents Sea Opening
3) Bering Strait
4) Amundsen Gulf
5) McClure Strait
6) Canadian Arctic Archipelago
7) Nares Strait
-----------------------------------
Sea ice volumes (in m^3) for the JRA-25 forced simulations are contained in the files named area_int_*.nc with variable name "ivol"
-----------------------------------
Basin-integrated liquid freshwater volumes for a further series of JRA-forced runoff perturbation experiments are contained within the file FWLvol_AO_Sref35_runoff.mat:
R_10: a step increase in runoff of 10%
R_60: a step increase in runoff of 60%
R_100: a step increase in runoff of 100%
The reference salinity is 35 and depth of integration 276.68m
