HEALPix support
with the latest versions of ecCodes, MIR and Atlas, Metview now supports the HEALPix grid, including:
conversion to Geopoints (
grib_to_geo()
)regridding from HEALPix to other grids (
regrid()
)extraction of latitudes and longitudes (
latitudes()
,longitudes()
)
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 (msymb()
).
Fixes:
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 standardregrid()
: fixed performance issue when processing ORCA grids from GRIBnearest_gridpoint()
: fixed issue when the input is one of: Lambert Azimuthal Equal Area, Mercator, HEALPixflextra_run()
: fixed issue where it could pick up the definition files of a different ecCodes from the one that FLEXTRA was built with
