earthkit.meteo.vertical.fieldlist.interpolate_pressure_to_height_levels(data, target_h, z, zs=None, h_type='geometric', h_reference='ground', interpolation='linear', aux_bottom_data=None, aux_bottom_h=None, aux_top_data=None, aux_top_h=None)¶

Interpolate data from pressure levels to height levels.

Parameters:

data (FieldList) – Data on pressure levels to be interpolated. Fields must correspond to a distinct set of pressure levels in arbitrary order. Must have at least two fields.
target_h (ArrayLike | FieldList | Field) – Target height levels (m). The type and reference of the height are defined by h_type and h_reference.
z (FieldList) – Geopotential (m2/s2) on the same pressure levels as data. The number of fields and levels must be the same as in data, but the level ordering can be different.
zs (FieldList|Field|None, optional) – Surface geopotential (m2/s2). Can be a single Field or a FieldList. If a FieldList is provided, it must contain exactly one Field. Only used when h_reference is “ground”.
h_type ({"geometric", "geopotential"}, default "geometric") –
Type of height to compute. Default is "geometric". Possible values:
- "geometric": geometric height (m)
- "geopotential": geopotential height (m)
h_reference ({"ground", "sea"}, default "ground") –
Reference level for the height calculation. Default is "ground". Possible values:
- "ground": height with respect to the ground/surface level
- "sea": height with respect to the sea level
interpolation ({"linear", "log", "nearest"}, default "linear") –
Interpolation mode. Default is "linear". Possible values:
- "linear": linear interpolation in height
- "log": linear interpolation in log-height
- "nearest": nearest level interpolation
aux_bottom_data (float | FieldList | Field | None) – Auxiliary data for interpolation below the bottom pressure level.
aux_bottom_h (float | FieldList | Field | None, optional) – Heights (m) of aux_bottom_data.
aux_top_data (float | FieldList | Field | None, optional) – Auxiliary data for interpolation above the top pressure level.
aux_top_h (float | FieldList | Field | None, optional) – Heights (m) of aux_top_data.

Returns:

Data interpolated to the target height levels. When interpolation is not possible for a given target height level, the corresponding output values are set to NaN.

Return type:

FieldList
