• 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

• 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.
• Cyclone XML tools
  Tools for use with Cyclone XML data are available from the CAWCR CXML website.
• NCAR Tools
  • 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. .
    NCL is provided with a couple of useful command line tools:
    
    • ncl_filedump - prints the contents of supported files in a netCDF-like view.
    • ncl_convert2nc - converts one or more files in any of the supported formats to netCDF formatted files.

  • PyNGL and PyNIO

    PyNGL and PyNIO provide a Python interface to most of the NCL tool tools 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 validate model forecasts using observational model validation data.

• NOAA Tools
  • NCEP tools for GRIB-2
    National Centers for Environmental Prediction (NCEP) provides a generalized set of codes for encoding, decoding and data manipulation in GRIB-2 format. Many TIGGE parameters will not be recognized using's NCEP's GRIB-2 table definitions.
  • wgrib2
    Climate Prediction Center (CPC) provides a tool (wgrib2) for examining and manipulating GRIB-2 files. Many TIGGE parameters will not be recognized using wgrib2. A mofified version of wgrib2 designed to read all TIGGE parameters can be downloaded here: tiggewgrib2.tar (only tested on Sun OS 2.10, and Linux).
  • ncBrowse
    ncBrowse is a GUI based tool that can be used to visualize TIGGE NetCDF data.
• Unidata tools

• • GEMPAK provides functionality for analysis of GRIB-2 data.
  • GRIB Java Decoder provides file manipulation functionality.
  • Unidata IDV is a GUI based tool that can be used to visualize both NetCDF and GRIB-2 data.

• NASA tool: 

  • Panoply is a GUI based tool that can be used to visualize TIGGE NetCDF data and easily compute/plot zonal averages.
