Extend the possible interpolation methods for different grids (mostly ICON grid data) #36
We already have interpolation functions and data structures for cartesian grids. Could we extend the interpolation functions to deal with icosahedral grids?
[ ] Literature research: Can libraries be used for it?
[ ] What routines can be shared with LaMETTA, YAC, ICON?
[ ] Implement an icosahedral met grid type.
[ ] Write a reading function for ico met type.
[ ] Implement index search functions for the ICON grid.
[ ] Implement a horizontal interpolation from the ICON grid to air parcel positions...
[ ] Implement a horizontal interpolation from the ICON grid to the lat-lon support grid, which is required for parameterizations.
[ ] Formulate a hybrid coordinate with potential temperature in the stratosphere and a non-hydrostatic coordinate in the troposphere.
[ ] Generalize the vertical coordinate system in MPTRAC.
[ ] Implement exact interpolations for winds on pressure levels that consider the tilt of the levels against the eta coordinate.
[ ] Implement the vertical interpolation function and combine it with the horizontal interpolations.
[ ] Implement a control flow to select between cartesian, icosahedral or any other potential grid geometry.
