earthkit.meteo.vertical.fieldlist.geometric_height_from_geopotential_height¶
- earthkit.meteo.vertical.fieldlist.geometric_height_from_geopotential_height(gh, R_earth=constants.R_earth)¶
Compute geometric height from geopotential height.
- Parameters:
gh (
FieldList|Field) – Geopotential height (m).R_earth (
float, optional) – Average radius of the Earth (m).
- Returns:
Geometric 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:
\[h = \frac{R_{earth} \cdot gh}{R_{earth} - gh}\]where \(R_{earth}\) is the average radius of the Earth (see
earthkit.meteo.constants.R_earth).
