This release provides support for octahedral reduced Gaussian grids, including the upcoming release resolution O1280 (Gaussian Grids supported by MARS and ProdGen). Also together with this preview is BUFR tables version 000406. To take full advantage of this preview, you should combine it with FFTW (fftw.org), which is a requirement for SH to octahedral interpolation. It requires grib_api/1.14.2.
In this preview release some unit tests fail, when comparing interpolation results (wrong GRIB header key) to reference data. These will be resolved on grib_api/1.14.3. The affected tests are:
- intuvp2_sh_vod_to_O80_compare
- intf2_sh_2t_to_O80_compare_cmp
- intf2_sh_vod_to_O80_compare_cmp
- intf2_sh_z_to_O80_compare_cmp
- intf2_N640_to_O80_compare
- intf2_O640_to_O80_compare_cmp
Since these are major changes we have decided to provide this first version as a preview and invite users to comment.
