HEALPix support
- with the latest versions of ecCodes, MIR and Atlas, Metview now supports the HEALPix grid, including:
- conversion to Geopoints (:func:`grib_to_geo`)
- regridding from HEALPix to other grids (:func:`regrid`)
- extraction of latitudes and longitudes (:func:`latitudes`, :func:`longitudes`)
- :func:`nearest_gridpoint`
In order to plot a GRIB file with data in HEALPix grid, it is suggested to convert to Geopoints, and plot the result with Symbol Plotting (:func:`msymb`).
Fixes:
- :func:`regrid`: fixed issue when regridding wind components (e.g. U/V) to a regular lat/lon grid; the values at the poles now vary as if in a ring, in conformance with the WMO standard
- :func:`regrid`: fixed performance issue when processing ORCA grids from GRIB
- :func:`nearest_gridpoint`: fixed issue when the input is one of: Lambert Azimuthal Equal Area, Mercator, HEALPix
- :func:`flextra_run`: fixed issue where it could pick up the definition files of a different ecCodes from the one that FLEXTRA was built with
