Points are not distributed +uniformly within an element, and elements are also not necessarily organized in +a simple way. For these reasons, remapping to regular grids becomes a +fundamental operations when inspecting the simulation output. In this section, +we describe the remappers currently available in `ClimaCore`. + +Broadly speaking, we can classify remappers in two categories: non-conservative, +and conservative. Conservative remappers preserve areas (and masses) when going +from the spectral grid to Cartesian ones. Conservative remappers are non-local +operations (meaning that they require communication between different elements) +and are more expensive, so they are typically reserved to operations where +physical conservation is important (e.g., exchange between component models in a +coupled simulation). On the other hand, non-conservative remappers are local to +an element and faster to evaluate, which makes them suitable to operations like +diagnostics and plotting, where having perfect physical conservation is not as +important. + +### Non-conservative remapping + +Non-conservative remappers are fast and don't require communication, but they +are not as accurate as conservative remappers, especially with large elements +with sharp gradients. These remappers are optimally suited for diagnostics and +plots. + +# `Remapper` + +The main remapper currently implemented utilizes a Lagrange interpolation with +the barycentric formula in [Berrut2004], equation (3.2), for the horizontal +interpolation. Vertical interpolation is linear except in the boundary elements +where it is 0th order. + +## Quick start + +Assuming you have a `ClimaCore` `Field` with name `field`, the simplest way to +interpolate into a uniform grid is with +```julia +julia> import ClimaCore.Remapping +julia> Remapping.interpolate(field) +``` + +This will return an Array with the `field` interpolated on some uniform grid +that is automatically determined based on the `Space` of definition of `field`. + +To obtain such coordinates, you can call the +[`Remapping.default_target_hcoords`](@ref) and +[`Remapping.default_target_zcoords`](@ref) functions. These functions return an +Array with the coordinates over which interpolation will occur. These arrays are +of `Geometry.Point`s. + +Multiple `fields` can be interpolated at the same time as long as they share the +underlying space. + + +[`Remapping.interpolate`](@ref) allocates new output arrays. As such, it is not +suitable for performance-critical applications. [`Remapping.interpolate!`](@ref) +performs interpolation in-place. Even better, it is to create a +[`Remapping.Remapper`](@ref) object and use it directly. + +## More performance + + + + +```julia +Remapper(space, target_hcoords, target_zcoords, buffer_length = 1) +Remapper(space; target_hcoords, target_zcoords, buffer_length = 1) +Remapper(space, target_hcoords; buffer_length = 1) +Remapper(space, target_zcoords; buffer_length = 1) +``` + +Return a `Remapper` responsible for interpolating any `Field` defined on the +given `space` to the Cartesian product of `target_hcoords` with +`target_zcoords`. + +`target_zcoords` can be `nothing` for interpolation on horizontal spaces. Similarly, `target_hcoords` can be `nothing` for interpolation on vertical spaces. + +The `Remapper` is designed to not be tied to any particular `Field`. You can use the same `Remapper` for any `Field` as long as they are all defined on the same `topology`. + +`Remapper` is the main argument to the `interpolate` function. + +### Keyword arguments + +`buffer_length` is size of the internal buffer in the Remapper to store intermediate values for interpolation. Effectively, this controls how many fields can be remapped simultaneously in `interpolate`.

If more fields are passed, the `remapper` will batch work with size up to its `buffer_length`. + +This call mutates the internal (private) state of the `remapper`. + + +`interpolate!` writes the output to the given `dest`ination. `dest` is expected to be defined on the root process and to be `nothing` for the other processes. + +**Note:** `interpolate` allocates new arrays and has some internal type-instability, `interpolate!` is non-allocating and type-stable. + +When using `interpolate!`, the `dest`ination has to be the same array type as the device in use (e.g., `CuArray` for CUDA runs). + +### Example + +Given `field1`,`field2`, two `Field` defined on a cubed sphere. + +```julia +longpts = range(-180.0, 180.0, 21) +latpts = range(-80.0, 80.0, 21) +zpts = range(0.0, 1000.0, 21) + +hcoords = [Geometry.LatLongPoint(lat, long) for long in longpts, lat in latpts] +zcoords = [Geometry.ZPoint(z) for z in zpts] + +space = axes(field1) + +remapper = Remapper(space, hcoords, zcoords) + +int1 = interpolate(remapper, field1) +int2 = interpolate(remapper, field2) + +# Or +int12 = interpolate(remapper, [field1, field2]) +# With int1 = int12[1, :, :, :] +``` + +## Convenience Interpolation + +```julia +interpolate(field::ClimaCore.Fields; + hresolution = 180, + resolution = 50, + target_hcoords = default_target_hcoords(space; hresolution), + target_zcoords = default_target_vcoords(space; vresolution) + ) +``` + +Interpolate the given fields on the Cartesian product of `target_hcoords` with `target_zcoords` (if not empty). + +Coordinates have to be `ClimaCore.Geometry.Points`. + +**Note:** do not use this method when performance is important.

Different `Field`s defined on the same `Space` can +share a `Remapper`, so that interpolation can be optimized. + +Example +======== + +Given `field`, a `Field` defined on a cubed sphere. + +By default, a target uniform grid is chosen (with resolution `hresolution` and +`zresolution`), so remapping is simply +```julia +julia> interpolate(field) +``` +This will return an array of interpolated values. + +Resolution can be specified +```julia +julia> interpolate(field; hresolution = 100, zresolution = 50) +``` +Coordinates can be also specified directly: +```julia +julia> longpts = range(-180.0, 180.0, 21) +julia> latpts = range(-80.0, 80.0, 21) +julia> zpts = range(0.0, 1000.0, 21) + +julia> hcoords = [Geometry.LatLongPoint(lat, long) for long in longpts, lat in latpts] +julia> zcoords = [Geometry.ZPoint(z) for z in zpts] + +julia> interpolate(field, target_hcoords, target_zcoords) +``` + +If you need the array of coordinates, you can call +[`default_target_hcoords`](@ref) (or [`default_target_vcoords`](@ref)) passing +`axes(field)`. This will return an array of `Geometry.Point`s. The functions +[`Geometry.Components`](@ref) and [`Geometry.Component`](@ref) can be used to extract the components as numeric +values.
