| Description: | 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,
and Fortran 90 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.
For GRIB encoding and decoding, the GRIB-API functionality is provided fully
in ecCodes with only minor interface and behaviour changes. Interfaces for C,
and Fortran 90 are all maintained as in GRIB-API. However, the
GRIB-API Fortran 77 interface is no longer available.
In addition, a new set of functions with the prefix "codes_" is provided to
operate on all the supported message formats. These functions have the same
interface and behaviour as the "grib_" functions.
A selection of GRIB-API tools has been included in ecCodes (ecCodes GRIB
tools), while new tools are available for the BUFR (ecCodes BUFR tools) and
GTS formats. The new tools have been developed to be as similar as possible
to the existing GRIB-API tools maintaining, where possible, the same options
and behaviour. A significant difference compared with GRIB-API tools is that
bufr_dump produces output in JSON format suitable for many web based
applications. |
