Ullman This directory contains all of the necessary files for regridding the new Green tidal dissipation dataset (diss_ITfric.nc) to the CESM grid. This new file contains only the dissipation due to internal wave drag and does not include the bottom drag dissapation (as in the original file). This new file is likely more appropriate/comparable to our tidal parameterization that removes dissipation in shallow depths (most bottom drag occurs on the shelves) New Green data file before regrid: diss_ITfric.nc In attempting to regrid the original fixed Green file to CESM using ncl, it was found that ncl balks at such high-resolution, so I regridded the Green data to the ETOPO20 (~1/3 deg resolution), which is the same resolution as the ER03 data (dis20.nc). Relevant files: regrid_newgreen_2_dis20grid.jnl : ferret script to do conservative regrid from original to ETOPO20 dis20.nc : ER03 data called by ferret script, only for target grid diss_green_ITfric_dis20res.nc : new Green data, regridded to ETOPO20 grid Note: the added benefit of this regrid to ETOPO20 grid is that we can use the ETOPO20 bathymetry data to do a subgridscale regrid to CESM (i.e. 3D from Schmittner and Egbert, 2014) *******2D regrid******* *********************** For 2D regrid, use diss_regrid_green_to_CESM_2D.ncl type "ncl diss_regrid_green_to_CESM_2D.ncl" (assuming ncl is loaded on your machine) A few notes on this script: 1. The current code is written to do a conservative regrid, but this can be adjusted to be bilinear interpolation or "nearest neighbor" at line 77 (or thereabouts) 2. This new Green data file no longer has negative dissipation in the original data, but negatives are "removed" just in case The total global dissipation in the original Green dataset is ~1.3 TW. Note, this is much less than the dissipation of the earlier files, due to the removal of the bottom drag dissipation. For comparison of global dissipation, one must scale to the differing areas. For CESM grid, this can be found in the file TAREA_CESMgrid.nc. In ferret, the global values of original files on a regular LAT/LON grid can be calculated using a definite integral (@din) Relevant files: diss_green_ITfric.CESM.conserve.2D.nc - final regridded output file diss_green_ITfric_SCRIP.nc - SCRIP file needed for regrid map_diss_green_TO_gx1v6.conserve.nc - regrid weights used in the interpolation gx1v6_SCRIP.nc - necessary SCRIP file containing CESM grid information *******3D regrid******* *********************** For 3D regrid, use diss_regrid_green_to_CESM_3D.ncl type "ncl diss_regrid_green_to_CESM_3D.ncl" (assuming ncl is loaded on your machine) Notes: 1. Like above, this code is set up to use a conservative regrid. Can be adjusted at line 105 2. Subgridscale parameterization assigns depth of dissipation in CESM 3D grid according to ETOPO20 bathymetry 3. All dissipation assigned to depths below CESM grid depth are summed an placed in bottom gridcell 4. negatives are set to zero after the regrid. diss_green_ITfric.CESMgrid.conserve.3D.nc - final 3D regridded file
