ecCodes is a package developed by ECMWF which provides an application programming interface and a set of tools for decoding and encoding messages in the following formats:

• WMO FM-92 GRIB edition 1 and edition 2
• WMO FM-94 BUFR edition 3 and edition 4
• WMO GTS abbreviated header (only decoding)

A useful set of command line tools provide quick access to the messages. C, Fortran 90 and Python interfaces provide access to the main ecCodes functionality.

ecCodes is an evolution of GRIB API. It is designed to provide the user with a simple set of functions to access data from several formats with a key/value approach.

1. Download ecCodes from https://software.ecmwf.int/wiki/display/ECC/Releases

2. Unpack distribution:

   tar -xzf eccodes-x.y.z-Source.tar.gz
   

3. Create a separate directory to build ecCodes:

   mkdir build
   cd build
   

4. Run cmake pointing to the source and specify the installation location:

   cmake  ../eccodes-x.y.z-Source -DCMAKE_INSTALL_PREFIX=/path/to/where/you/install/eccodes
   

   It is strongly recommended that you install into a clean directory

5. Compile, test and install:

   make
   ctest
   make install
   

To add the Python3 bindings, use pip3 install from PyPI as follows:

pip3 install eccodes

or

pip3 install --install-option="--prefix=/path/to/where/you/install/eccodes" eccodes
