Deprecations

The interpolate() method is replaced by regrid()

Using MIR for regridding

The default backend for the newly added regrid() method is now MIR, ECMWF’s MIR (Meteorological Interpolation and Regridding) library. See the notebook examples:

• MIR: regridding numpy arrays

• MIR: regridding HEALPix GRIB fieldlist

• MIR: regridding octahedral GRIB fieldlist

• MIR: using different interpolations

The regrid method

The interpolate() method was replaced by regrid(), which provides a more flexible and powerful interface for regridding data. The new method allows you to specify different backends and options for regridding. The following backends are available:

Backend	Description
mir	use ECMWF’s Meteorological Interpolation and Regridding library (MIR) to perform the regridding. This is the default.
precomputed	use precomputed interpolation weights stored in a remote inventory managed by ECMWF
precomputed-local	use precomputed interpolation weights stored in a local inventory

Other new features

• Added configuration control. Currently, it is only related to the precomputed and precomputed-local backends in regrid(). See the Configuration notebook for details.

• Added in-memory cache for precomputed interpolation weights for the precomputed and precomputed-local backends. See the Matrix memory cache notebook for details.
