mesmer.io.load_constant_files.load_regs_ls_wgt_lon_lat(reg_type, lon, lat)

Load constant files.

Parameters

  • reg_type (str) – region type (“ar6.land”, “countries”, “srex”)

  • lon (dict) – longitude dictionary with key

    • [“c”] (1d array with longitudes at center of grid cell)

  • lat (dict) – latitude dictionary with key

    • [“c”] (1d array with latitudes at center of grid cell)

Returns

  • reg_dict (dict) – region dictionary with keys

    • [“type”] (region type)

    • [“abbrevs”] (abbreviations for regions)

    • [“names”] (full names of regions)

    • [“grids”] (3d array (region, lat, lon) of subsampled region fraction)

    • [“grid_b”] (2d array (lat, lon) of regions with each grid point being assigned to a single region (“binary” grid))

    • [“full”] (full Region object (for plotting region outlines))

  • ls (dict) – land-sea dictionary with keys

    • [“grid_raw”] (2d array (lat, lon) of subsampled land fraction)

    • [“grid_no_ANT”] (grid_raw with Antarctica removed)

  • wgt (np.ndarray) – 2d array (lat,lon) of weights to be used for area weighted means

  • lon (dict) – longitude dictionary with added keys

    • [“e”] (1d array with longitudes at edges of grid cells)

    • [“grid”] (2d array (lat,lon) of longitudes)

  • lat (dict) – latitude dictionary with added keys

    • [“e”] (1d array with latitudes at edges of grid cells)

    • [“grid”] (2d array (lat,lon) of latitudes)

Notes

  • If additional region types are added in this function, mesmer.utils.select.extract_land() needs to be adapted too
