earthkit.meteo.vertical.fieldlist.geopotential_from_geometric_height

earthkit.meteo.vertical.fieldlist.geopotential_from_geometric_height(h, R_earth=constants.R_earth)

Compute geopotential from geometric height.

Parameters:

• h (FieldList|Field) – Geometric height with respect to the sea level (m).

• R_earth (float, optional) – Average radius of the Earth (m).

Returns:

Geopotential (m2/s2). The result has the same type as the input (FieldList or Field).

Return type:

FieldList|Field

Notes

The computation is based on the following formula:

\[z = \frac{h \cdot g \cdot R_{earth}}{R_{earth} + h}\]

where

• \(R_{earth}\) is the average radius of the Earth (see earthkit.meteo.constants.R_earth)

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