earthkit.meteo.vertical.fieldlist.geopotential_height_from_geometric_height¶
- earthkit.meteo.vertical.fieldlist.geopotential_height_from_geometric_height(h, R_earth=constants.R_earth)¶
Compute geopotential height 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 height (m). 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:
\[gh = \frac{h \cdot R_{earth}}{R_{earth} + h}\]where \(R_{earth}\) is the average radius of the Earth (see
earthkit.meteo.constants.R_earth).
