  • GRIB_API
    ECMWF has developed a C GRIB API for encoding, decoding and data manipulation in GRIB-2 format. All TIGGE parameters should be recognized through GRIB_API.
  • grib2_to_netcdf
    grib2_to_netcdf is an NCAR  conversion utility built on the ECMWF GRIB_API and Unidata NetCDF libraries. The utility converts regular lat/lon gridded TIGGE data from GRIB-2 to NetCDF format.

Other External tools

  • NCAR TIGGE portal
    A wide range of tools for manipulating TIGGE data is available there. They include tools from a range of different providers to visualise and manipulate GRIB2 and netcdf data, and to support model validationTools
    • NCL
      The NCAR Command Language (NCL) is a free interpreted language designed specifically for scientific data processing and visualization. NCL has robust file input and output with support for NetCDF, HDF, GRIB-1 and GRIB-2 file formats, including support for all published TIGGE GRIB-2 parameters. 

    • PyNGL and PyNIO

      PyNGL and PyNIO provide a Python interface to most of the NCL tool and its functionality, with an emphasis on high quality 2D visualizations. PyNIO, in particular supports TIGGE GRIB-2 with the functionality provided by NCL.

    • MET
      Model EvaluationTools (MET) is a suite of software utilities designed by NCAR Developmental Testbed Center (DTC) to the provide the capability to verify model forecasts using observational model validation data.

  • TIGGE Museum
    The museum includes a set of scripts to download TIGGE data, and plot it (using GrADS ) in file TIGGE_sample.tar.gz - available directly from here.
