Vertical interpolation and re-mapping (vertical_interpolation
/ std
)¶
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¶
method: (mandatory)
- Method used for the interpolation
static-levels:
linear: a linear interpolation. Uses the coordinate specified in
coord_out
closest: gets closest levels
accepted values:
static-levels: determines levels from pre-determined levels as specified in the argument
file_statlev
linear: a linear interpolation. Uses the coordinate specified in
coord_out
closest: gets closest levels
match-layer: finds the layer matching outputs.
layer-weighted: finds the layers matching outputs, and weights according to the thickness in each input layers
Optional arguments¶
parameter: (optional)
Parameter name on which the transform works on
accepted type: str
component: (optional)
Component name on which the transform works on
accepted type: str
orig_parameter_plg: (optional)
Plugin object on which the transform works on
accepted type: Plugin
orig_component_plg: (optional)
Corresponding component object on which the transform works on
accepted type: Plugin
successor: (optional)
Name of the successor transform
accepted type: str
precursor: (optional)
Name of the precursor transform
accepted type: str
coord_in: (optional): pres
Coordinates for inputs, pres, height
accepted type: str
file_statlev: (optional):
File with model levels in which stations are. The expected format is:
#STAT LAT LON LEV alt(m) ALT 82.45 -62.52 1 210 JFJ 46.548 7.987 10 3580 MHD 53.33 -9.9 1 8The first line is ignored. The important informations are the first columns with the station ID (should be consistent with the station name in your monitor file, and the fourth column specifying the level in the model (in python index starting from 0)
accepted type: str
ignore_level: (optional): False
Don’t do any vertical interpolation for sparse data and just propagate levels from inputs and outputs
accepted type: bool
coord_out: (optional): pres
Coordinates for outputs
accepted type: str
psurf: (optional): 1013.25
Standard surfce pressure to use in computations with alpha/beta coordinate
accepted type: float
fill_nans: (optional): False
Use in combination with
method
=linear
. Fill values outside the convex hull of inputs by using the closest valid (above or below) valueaccepted type: bool
target_top: (optional): False
Interpolate to the top of a domain
accepted type: bool
sparse_in: (optional): False
Whether inputs are sparse data
accepted type: bool
sparse_out: (optional): False
Whether outputs are sparse data
accepted type: bool
