Attribute Value
Methodology
  • The MMP observations were provided by Gunnar Voet at Scripps. The model data was computed using the MITgcm ( http://mitgcm.org/) on the Niagara supercomputer located in Toronto, CA. The model data was gathered and processed by the data set creator.
Description
  • These MATLAB data files contain all the observations and model output used in the article Improved Internal Gravity Wave Spectral Continuum in a Regional Ocean Model by Nelson et al., recently submitted to Journal of Geophysical Research: Oceans.

These MATLAB data files contain all the data used in the article
Improved Internal Gravity Wave Spectral Continuum1in a Regional Ocean Model
by Nelson et al., 2019.

Obs_* files contain data from the MMP observations. The other files are
from the MITgcm ocean model runs with the following labels:
LLC4320: global run, 2km horizontal spacing, 90 depth levels
One-to-One: regional run, 2km horizontal spacing, 90 depth levels
Finer-Dz: regional run, 2km horizontal spacing, 270 depth levels
Finer-Dx: regional run, 0.25km horizontal spacing, 90 depth levels
Finer-Both: regional run, 0.25km horizontal spacing, 270 depth levels

NOTES:
- LLC4320 is also studied in other works (e.g., Savage et al. 2017)
- The regional run is forced at the boundaries by LLC4320.
- The region simulated is 24N-32N, 193E-199E.

Each file contains the following variables:
Variable Dimensions Units Full name
x 1 x 1 Degrees Longitude
y 1 x 1 Degrees Latitude
z nz x 1 meters Depth (positive downwards)
p nz x 1 dbars Pressure
t 1 x nt d.o.y. Time in day of year (d.o.y.)
T nz x nt Deg. Celsius Measured temperature (NOTE: This is not potential temperature!)
S nz x nt psu Practical salinity (NOTE: This is equal to absolute salinity for the model!)
U nz x nt m/s Zonal velocity
V nz x nt m/s Meridional velocity
W nz x nt m/s Vertical velocity (positive upwards)

Dimension definitions:
nz: # of depth levels
nt: # of time steps
