set_gridparams_ESGgrid module

set_gridparams_ESGgrid(lon_ctr, lat_ctr, nx, ny, halo_width, delx, dely, pazi, constants)

Sets the parameters for a grid that is to be generated using the “ESGgrid” grid generation method (i.e., when GRID_GEN_METHOD: "ESGgrid").

Parameters:

  • lon_ctr (float) – The longitude of the center of the grid (in degrees).

  • lat_ctr (float) – The latitude of the center of the grid (in degrees).

  • nx (int) – The number of cells in the zonal direction on the regional grid.

  • ny (int) – The number of cells in the meridional direction on the regional grid.

  • halo_width (int) – The width (in number of grid cells) of the wide halo to add around the regional grid before shaving the halo down to the width(s) expected by the forecast model. For predefined grids, this value is set in setup.py based on the ESGgrid_WIDE_HALO_WIDTH value in predef_grid_params.yaml.

  • delx (float) – The cell size in the zonal direction of the regional grid (in meters).

  • dely (float) – The cell size in the meridional direction of the regional grid (in meters).

  • pazi (float) – The rotational parameter for the “ESGgrid” (in degrees).

  • constants (dict) – Dictionary of SRW constants

Returns:

Dictionary of inputs and 4 outputs (see return statement in code for details)
