Notes

  • This release provides support for octahedral reduced Gaussian grids
  • This release requires grib_api/1.14.2
  • Tested against BUFR tables version 000406, please check also changes of the previous version 000405

  • Changes to HIRLAM functions interface, CHARACTER*1 HTYPE as new argument as follows:

    • HIRLAM(L12PNT,OLDFLD,KOUNT,KGAUSS,HTYPE,AREA,POLE,GRID,NEWFLD,KSIZE,NLON,NLAT)
    • HIRLSM(L12PNT,OLDFLD,KOUNT,KGAUSS,HTYPE,AREA,POLE,GRID,NEWFLD,KSIZE,NLON,NLAT)
    • HIRLAMW(L12PNT,OLDFLDU,OLDFLDV,KOUNT,KGAUSS,HTYPE,AREA,POLE,GRID,NEWFLDU,NEWFLDV,KSIZE,NLON,NLAT)
  • HTYPE should be one of:
    • 'R' for "quasi-regular" reduced Gaussian grid (equivalent to 'N')
    • 'O' for octahedral reduced Gaussian grid, or
    • 'F' for regular Gaussian grid
    • 'U' for a user-defined gaussian grid
  • New HSH2GG function, controlling SH interpolation to Gaussian grids, replaces:
    • HSP2GG
    • HSP2GG2
    • HSP2GG3
  • New INTOUT parameter name CHARACTER*(*) HPARN "gridname", interpreting parameter value CHARACTER*(*) CHARV, describing a list of supported grids as in Gaussian Grids supported by MARS and ProdGen. This is the available method to set interpolation to octahedral reduced Gaussian grids.

  • Build system:

    • conditional compilation of components (interpolation, GRIBEX and BUFR)

    • revision of definitions and code reusing, stricter compilation options

  • FFTW is an optional Fast Fourier Transform library dependency, required for SH to octahedral reduced Gaussian grid interpolations
  • Improved interpolation testing
  • Added new HIRLAM LSM masks for specific reduced Gaussian grids:
    • N64, N96, N512, N128
    • O64, O80, O96, O128, O160, O200, O256, O320, O400, O512, O640, O1024, O1280
  • When using INTF2  (e.g. via MARS),  GRIB "latitudeOfLastGridPoint" for wave model interpolations in some cases was encoded wrongly to -79.0xx and is now corrected to be -90+0.5*inc (see

    )

Known issues

  • This release is a preview release, and fails some unit tests. The failures happen when comparing interpolation results to reference data (bundled with the package), where the results GRIB header (wrong) are different from the reference data (correct). This is a known issue with grib_api/1.14.2 and will be resolved on grib_api/1.14.3. The affected tests are:
    • 8 - intuvp2_sh_vod_to_O80_compare (Failed)
    • 19 - intf2_sh_2t_to_O80_compare_cmp (Failed)
    • 30 - intf2_sh_vod_to_O80_compare_cmp (Failed)
    • 41 - intf2_sh_z_to_O80_compare_cmp (Failed)
    • 57 - intf2_N640_to_O80_compare (Failed)
    • 68 - intf2_O640_to_O80_compare_cmp (Failed)
