ECMWF grib2 data files (ECMWF / grib2)¶
Description¶
Read grib files from ECMWF
Grib files are provided either for 3D fields or, for surface variables, for 2D fields. Activate the surface option for treating 2D grib files. In case of grib files for cumulated variables, activate the decumul option. In this case 2 dates are saved in the fetch list and the decumulation is next_date - date
Yaml arguments¶
The following arguments are used to configure the plugin. pyCIF will return an exception at the initialization if mandatory arguments are not specified, or if any argument does not fit accepted values or type:
Optional arguments¶
decumul: (optional): False
activates decumulation
accepted type: <class ‘bool’>
surface: (optional): False
for treating 2D fields (e.g. surface variables)
accepted type: <class ‘bool’>
expand_psurf: (optional): False
Expand surface pressure to full pressure field
accepted type: <class ‘bool’>
pressure_thickness: (optional): False
Returns the pressure thickness of each level. To be used with expand_psurf
accepted type: <class ‘bool’>
domain_file: (optional)
Name of the file to use to deduce the domain, if different from the file format specified for data reading
accepted type: <class ‘str’>
