CoordSys

class ESMF.api.constants.CoordSys

This flag indicates the coordinate system of a Grid. This value is useful both to indicate to other users the type of the coordinates, but also to control how the coordinates are interpreted in regridding methods (e.g. Regrid()).

CART = <CoordSys.CART: 0>

Cartesian coordinate system. In this system, the Cartesian coordinates are mapped to the Grid coordinate dimensions in the following order: x,y,z. (e.g. using coord_dim=1 in Grid.get_coords() references the y dimension)

SPH_DEG = <CoordSys.SPH_DEG: 1>

Spherical coordinates in degrees. In this system, the spherical coordinates are mapped to the Grid coordinate dimensions in the following order: longitude, latitude, radius. (E.g. using coord_dim=1 in Grid.get_coords() references the latitude dimension) Note, however, that Regrid() currently just supports longitude and latitude (i.e. with this system, only Grids of dimension 2 are supported in the regridding).

SPH_RAD = <CoordSys.SPH_RAD: 2>

Spherical coordinates in radians. In this system, the spherical coordinates are mapped to the Grid coordinate dimensions in the following order: longitude, latitude, radius. (E.g. using coord_dim=1 in Grid.get_coords() references the latitude dimension) Note, however, that Regrid() currently just supports longitude and latitude (i.e. with this system, only Grids of dimension 2 are supported in the regridding).
