earthkit.meteo.vertical.xarray.geometric_height_from_geopotential_height¶
- earthkit.meteo.vertical.xarray.geometric_height_from_geopotential_height(gh, R_earth=constants.R_earth)¶
Compute the geometric height from geopotential height.
- Parameters:
gh (
xr.DataArray) – Geopotential height (m)R_earth (
float) – Average radius of the Earth (m)
- Returns:
Geometric height (m)
- Return type:
xr.DataArray
The computation is based on the following formula:
\[h = \frac{R_{earth} gh}{R_{earth} - gh}\]where \(R_{earth}\) is the average radius of the Earth (see
earthkit.meteo.constants.R_earth)
