Grid

Staggered grid wrapping a base curvilinear grid — A / B / C / D variants — with per-stagger location keys.

Logically rectangular Cartesian mesh with optional non-uniform spacing per axis (1D / 2D / 3D).

Six gnomonic panels covering the sphere; in-panel curvilinear (ξ, η) coordinates with cross-panel ghost stitching.

Geodesic triangular mesh on the sphere; recursively subdivided icosahedron.

Regular spherical lat-lon mesh with metric corrections for the spherical surface.

Quasi-uniform Voronoi mesh on the sphere with icosahedral dual (12 pentagons + hexagons).

1D vertical column with arbitrary level spacing — pressure / sigma / hybrid coordinates.
