Here is what has worked for me:. Wait til you see the final cfgrib implementation that allow writing to gribs (soon, currently in alpha) as well. In this case, the file only contains one kind of vertical level # - pressure (hPa), but it could conceivably contain output on sigma levels, hybrid # sigma coordinates, altitude etc. Note: this package is in the process of being replaced by ecCodes which is a superset of GRIB API. GRIB2 format data for eccodes-lib - 0. Variations in the way pressure level fields can be stored, and in the parameter IDs used for each field, mean that. More subroutine codes_bufr_new_from_samples (bufrid, samplename, status) Create a new valid bufrid from a BUFR sample contained in a samples directory pointed by the environment variable ECCODES_SAMPLES_PATH. This move was done to align with the ECMWF and their commitment to only developing the GRIB API within ecCodes and not as a separate library. You can also use eccodes (then you need to change your loader flags in the makefile accordingly). You can get basic information about the content of a GRIB file from the command line using the grib/eccodes utilities, for example by applying grib_ls. Templates. 使用 ecCodes 和 scipy 实现对 GRIB2 文件的裁剪与插值. ecCodes is now the primary GRIB encoding/decoding package used at ECMWF. ecCodes is an evolution of GRIB-API.
