                                             --output OUTPUT

Named Arguments

--source-grid

Input file (GRIB or NetCDF).

--target-grid

Input file (GRIB or NetCDF).

--mir

MIR command (default: ‘mir’).

Default: “mir”

--rounding

Round latitudes and longitudes to this precision (default: None).

--check

Check for duplicate lat/lon pairs.

Default: False

--mir_args

MIR arguments. Usage: –mir_args arg1=val1 arg2=val2 …

--output

Output NPZ file. The name will be used to determine the type of regrid file to create.

Named Arguments

--lam-grid: Input file (GRIB or NetCDF).
--global-grid: Input file (GRIB or NetCDF).
--distance-km: Distance in kilometers to consider for the mask. If None, use the spacing of the global grid.
--output: Output NPZ file. The name will be used to determine the type of regrid file to create.
--plot: A path in which to plot the mask.
