grib2io-interp: Interpolation Component Package for grib2ioIntroductiongrib2io-interpis an interpolation component package forgrib2io.  This package provides a Python interface to theNCEPLIBS-ipFortran library via a NumPy/F2PY extension module.  Originally, grib2io-interp was a part of the grib2io package, but since it requires NumPy.distutils to build and install, it needs to be handled separately from the main grib2io source that are usingsetuptools.  This package contains an extension module,interpolate, that provides interfaces to Fortran subroutines and these subroutines serve as wrappers to NCEPLIBS-ip subroutines.  The following table illustrates the mapping:grib2io-interpNCEPLIBS-ipinterpolate.interpolate_scalaripolates_grib2interpolate.interpolate_vectoripolatev_grib2NOTE:It is recommended that you usegrib2io.interpolatefunction to access the interpolation subroutines provided by grib2io-interp.DocumentationNOAA-MDL/grib2io-interpRequired SoftwareDespite this package being a component for grib2io, grib2io is not a formal dependency for grib2io-interp.Python3.8, 3.9, 3.10, and 3.11NCEPLIBS-ip5.0.0+setuptools 61.0+NumPy 1.22+Fortran Compiler: GNU (gfortran) and Intel (ifort) have been tested.NCEPLIBS-ipIMPORTANT:Beginning with version 5.0.0 of the NCEP Interpolation(NCEPLIBS-ip)library, the NCEP Spectral Interpolation(NCEPLIBS-sp)library is now integrated into NCEPLIBS-ip.InstallationIf NCEPLIBS-ip has been installed to custom location (i.e. not default paths), then define the root of the installation via environment variableIP_DIR.pipinstallgrib2io-interpBuild and Install from SourceClone GitHub repository or download a source release fromGitHuborPyPI.Editsetup.cfgto define the NCEPLIBS-ip library installation pathORdefineIP_DIRenvironment variable.Build and install.

Therefore, the development evolution of grib2io will mainly focus on how best to serve that purpose and its primary user's -- mainly meteorologists, physical scientists, and software developers supporting the missions within NOAA's National Weather Service (NWS) and National Centers for Environmental Prediction (NCEP), and other NOAA organizations.DisclaimerThis repository is a scientific product and is not official communication of the National Oceanic and Atmospheric Administration, or the United States Department of Commerce.
