IntroductionThe ECMWF grib_api software library provides a set of functions/subroutines and command line tools for encoding and decoding WMO FM-92 GRIB edition 1 and edition 2 messages. The OpenIFS model uses GRIB for its input and output files. The grib_api software library must be build and installed before you try to build OpenIFS on your system. Although you may have a version of grib_api on your system already that would most likely work, it is recommended that you build and install the version of the software provided on the OpenIFS ftp site. This version will have been tested with OpenIFS and known to work. For more information about grib_api, please visit the grib_api website. |
