Coordinates

Geometry.AbstractPoint
Geometry.float_type

Points represent locations in space, specified by coordinates in a given coordinate system (Cartesian, spherical, etc), whereas vectors, on the other hand, represent displacements in space.

An analogy with time works well: times (also called instants or datetimes) are locations in time, while, durations are displacements in time.

Note 1: Latitude and longitude are specified via angles (and, therefore, trigonometric functions: cosd, sind, acosd, asind, tand,...) in degrees, not in radians. Moreover, lat (usually denoted by \theta) \in [-90.0, 90.0], and long (usually denoted by \lambda) \in [-180.0, 180.0].

Note 2:: In a Geometry.LatLongZPoint(lat, long, z), z represents the elevation above the surface of the sphere with radius R (implicitly accounted for in the geoemtry).

Note 3: There are also a set of specific Cartesian points (Cartesian1Point(x1), Cartesian2Point(x2), etc). These are occasionally useful for converting everything to a full Cartesian domain (e.g. for visualization purposes). These are distinct from XYZPoint as ZPoint can mean different things in different domains.

Spaces

A Space represents a discretized function space over some domain. Currently two main discretizations are supported: Spectral Element Discretization (both Continuous Galerkin and Discontinuous Galerkin types) and a staggered Finite Difference Discretization. Combination of these two in the horizontal/vertical directions, respectively, is what we call a hybrid space.

Sketch of a 2DX hybrid discretization:

Finite Difference Spaces

ClimaCore.jl supports staggered Finite Difference discretizations. Finite Differences discretize an interval domain by approximating the function by a value at either the center of each element (also referred to as cell) (CenterFiniteDifferenceSpace), or the interfaces (faces in 3D, edges in 2D or points in 1D) between elements (FaceFiniteDifferenceSpace).

Users should construct either the center or face space from the mesh, then construct the other space from the original one: this internally reuses the same data structures, and avoids allocating additional memory.
