Precomputed weights inventory

Warning

With the precomputed backend we can only perform the regridding if the pre-generated interpolation weights for the given source and target gridspec combination are available. At the moment, the support is limited to the following cases:

• only global grids are supported

• for regular latitude-longitude grids only the default scanning mode used at ECMWF is supported (values start at North-West and follow in consecutive rows from West to East)

The pages below contain all the source and target gridspec combinations for which precomputed weights are available. The information is grouped by source grid type.

• reduced_gg (octahedral)
• reduced_gg
• healpix (ring)
• healpix (nested)
• regular_ll
• orca
