pyremap.descriptor.LatLonGridDescriptor.read

classmethod LatLonGridDescriptor.read(filename=None, ds=None, lat_var_name='lat', lon_var_name='lon', mesh_name=None, regional=None)[source]

Read the lat-lon grid from a file with the given lat/lon var names.

Parameters:

  • filename (str, optional) – The path of the file containing the lat-lon grid (if ds is not supplied directly)

  • ds (xarray.Dataset, optional) – The path of the file containing the lat-lon grid (if supplied, filename will be ignored)

  • lat_var_name (str, optional) – The name of the latitude and longitude variables in the grid file

  • lon_var_name (str, optional) – The name of the latitude and longitude variables in the grid file

  • mesh_name (str or None, optional) – The name of the mesh or grid, used to give mapping files unique names

  • regional (bool or None, optional) – Whether this is a regional or global grid. If None, this will be determined automatically by checking the limits of the corner latitude and longitude to see if they cover the globe.
