DIAGMET meteorological processing for CHIMERE (diagmet
/ std
)¶
Description¶
This transform replicates what was done in the historical diagmet.f90 script associated to CHIMERE. It processes variables from ECMWF grib files to produce variables required by CHIMERE.
Warning
At the moment, the yaml is not convenient to use. Every input parameter must be included. In the future, something equivalent to ecm_par.f90 should be implemented.
For the time being, please use the following yaml sample in your datavect paragraph:

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:
Mandatory arguments¶
file_landuse: (mandatory)
Path to the LANDUSE file (computed elsewhere)
accepted type: <class ‘str’>
file_landpar: (mandatory)
Path to the LANDPAR file
accepted type: <class ‘str’>
Optional arguments¶
pblmin: (optional): 20
Minimum PBL height
accepted type: <class ‘float’>
uwinfac: (optional): False
Use urban wind correction in the surface layer.
Warning
In the original diagmet, the values were inverted. One should use 1 to disable the function and 0 to activate it. Now, True means using it and False not using it.
accepted type: <class ‘bool’>
uflxadd: (optional): False
Use additional urban heat flux
accepted type: <class ‘bool’>
upblmin: (optional): False
Use urban correction for minimal urban PBL height
accepted type: <class ‘bool’>
cice: (optional): True
Use cloud ice water in addition to cloud liquid water
accepted type: <class ‘bool’>
rain: (optional): False
Use rain water in addition to cloud liquid water
accepted type: <class ‘bool’>
clol: (optional): 0
Use low clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity
accepted type: <class ‘int’>
clom: (optional): 0
Use medium clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity
accepted type: <class ‘int’>
cloh: (optional): 0
Use high clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity
accepted type: <class ‘int’>
usta: (optional): recompute
Read Ustar or recompute from Louis 1982
accepted values: [‘read’, ‘recompute’]
deepc: (optional): True
Read deep convection (it False, put all DP fluxes at 0)
accepted type: <class ‘bool’>
