v5.1.0

We are pleased to announce the release of version 5.1.0 of NCEPLIBS-ip.

The NCEP general interpolation library contains Fortran 90 subprograms to be used for interpolating between nearly all (rectilinear) grids used at NCEP, as well as spectral processing routines.

For more detailed documentation see https://noaa-emc.github.io/NCEPLIBS-ip/.

New This Release

• WMO and NCEP rotated lat-lon grids are now both supported (#231, #241)
• sp routines are now accessed through sp_mod (#230)
• ipxetas is now deprecated (disabled by default; #245)
• LU decomposition routines have been replaced with LAPACK equivalents (#227)

Version 5.0.0

We are pleased to announce the release of version 5.0.0 of NCEPLIBS-ip.

The NCEP general interpolation library contains Fortran 90 subprograms to be used for interpolating between nearly all (rectilinear) grids used at NCEP.

For more detailed documentation see https://noaa-emc.github.io/NCEPLIBS-ip/.

New This Release

• This releases merges the functionality of NCEPLIBS-sp library (as of v2.5.0) into NCEPLIBS-ip (#93). The subroutines from the sp library can be accessed in the same way as before, i.e., simply link to ip v5.0.0 and they will be available without the need for use statements (this will change in the next release, where former sp functionality will be accessed through Fortran modules). In most cases, codes using NCEPLIBS-sp should be able to remove any sp-related module loads or CMake find_library or find_package calls and use NCEPLIBS-ip v5.0.0 instead without further code modification. Note that NCEPLIBS-sp documentation has been merged into the updated NCEPLIBS-ip documentation.
• Fixed a bug that was causing issues for building tests with multiple make threads. (#209)

What's Changed

• add v4.3.0 and v4.4.0 to package.py by @AlexanderRichert-NOAA in #208
• Merge sp into ip by @AlexanderRichert-NOAA in #210

Full Changelog: v4.4.0...v5.0.0

Version 4.4.0

We are pleased to announce the release of version 4.4.0 of NCEPLIBS-ip.

The NCEP general interpolation library contains Fortran 90 subprograms to be used for interpolating between nearly all (rectilinear) grids used at NCEP.

For more detailed documentation see https://noaa-emc.github.io/NCEPLIBS-ip/.

New This Release

• The NCEPLIBS-ip CMake config is generalized to support any combination of _4/_d/_8 builds (#199). Without this fix, users must build the _4 version in order for the ip package to be found by dependent CMake configurations (e.g., grib_util, UFS_UTILS).

Version 4.1.0

We are pleased to announce the release of version 4.1.0 of NCEPLIBS-ip.

The NCEP general interpolation library (iplib) contains Fortran 90 subprograms to be used for interpolating between nearly all (rectilinear) grids used at NCEP.

For more detailed documentation see https://noaa-emc.github.io/NCEPLIBS-ip/.

New This Release

• Fixes and improvements for station point interpolation (#167)
• Many documentation improvements (see #97 , #96, #95, #89, #60, #100)
• Improvements in CI system (see #87, #74, #131, #172, #175)
• Updates to build options for real precision and shared vs. static (#129, #135, #136, #140, #180)

For more detailed documentation see https://noaa-emc.github.io/NCEPLIBS-ip/.

New This Release

• Combined the ip and ip2 libraries. Existing interfaces remain the same, but they are now in a Fortran module. Add use ip_mod to access ip/ip2 routines (see #38).
• Compiler will be more strict about proper typke/kind/rank passed to subroutines.
• The individual tests from ip/ip2 pass along with the regression tests from UFS_UTILS.
• Converted documentation to Doxygen. See #22
