earthkit.meteo.vertical.geopotential_from_geopotential_height

earthkit.meteo.vertical.geopotential_from_geopotential_height(gh: ArrayLike) → ArrayLike

earthkit.meteo.vertical.geopotential_from_geopotential_height(gh: xarray.DataArray) → xarray.DataArray

earthkit.meteo.vertical.geopotential_from_geopotential_height(gh: earthkit.data.FieldList) → earthkit.data.FieldList

Compute geopotential from geopotential height.

Parameters:

gh (array-like | xarray.DataArray | FieldList) – Geopotential height (m).

Returns:

Geopotential (m2/s2).

Return type:

array-like | xarray.DataArray | FieldList

The computation is based on the following definition:

\[z = gh \cdot g\]

where \(g\) is the gravitational acceleration on the surface of the Earth (see earthkit.meteo.constants.g).

Implementations

geopotential_from_geopotential_height() calls one of the following implementations depending on the type of the input arguments:

• earthkit.meteo.vertical.array.geopotential_from_geopotential_height() for array-like

• earthkit.meteo.vertical.xarray.geopotential_from_geopotential_height() for xarray.DataArray

• earthkit.meteo.vertical.fieldlist.geopotential_from_geopotential_height() for FieldList

The function returns an object of the same type as the input arguments.
