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¶
dir: (optional):
Path to the corresponding component. This value is used if not provided in parameters
accepted type: str
file: (optional):
File format in the given directory. This value is used if not provided in parameters
accepted type: str
varname: (optional):
Variable name to use to read data filesinstead of the parameter name if different to the parameter name
accepted type: str
file_freq: (optional): 3H
Frequency at which files are saved
accepted type: str
decumul: (optional): False
activates decumulation
accepted type: bool
cumul_length: (optional): 12
if cumulation length differ from 12h, in hour
accepted type: int
surface: (optional): False
for treating 2D fields (e.g. surface variables)
accepted type: bool
expand_psurf: (optional): False
Expand surface pressure to full pressure field
accepted type: bool
pressure_thickness: (optional): False
Returns the pressure thickness of each level. To be used with expand_psurf
accepted type: 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: str
