DIAGMET meteorological processing for CHIMERE diagmet/std

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 : str, mandatory

Path to the LANDUSE file (computed elsewhere)

file_landpar : str, mandatory

Path to the LANDPAR file

Optional arguments#

parameter : str, optional

Parameter name on which the transform works on

component : str, optional

Component name on which the transform works on

orig_parameter_plg : Plugin, optional

Plugin object on which the transform works on

orig_component_plg : Plugin, optional

Corresponding component object on which the transform works on

successor : str, optional

Name of the successor transform

precursor : str, optional

Name of the precursor transform

pblmin : float, optional, default 20

Minimum PBL height

uwinfac : bool, optional, default 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.

uflxadd : bool, optional, default False

Use additional urban heat flux

upblmin : bool, optional, default False

Use urban correction for minimal urban PBL height

cice : bool, optional, default True

Use cloud ice water in addition to cloud liquid water

rain : bool, optional, default False

Use rain water in addition to cloud liquid water

clol : int, optional, default 0

Use low clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity

clom : int, optional, default 0

Use medium clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity

cloh : int, optional, default 0

Use high clouds: 0 = read, 1 = use liquid water, 2 = use relative humidity

usta : “read” or “recompute”, optional, default “recompute”

Read Ustar or recompute from Louis 1982

deep_convection : bool, optional, default True

Read deep convection (it False, put all DP fluxes at 0)

Requirements#

The current plugin requires the present plugins to run properly:
