geometric_height_from_geopotential

geometric_height_from_geopotential(z)

New in Metview version 5.23.0

Compute the geometric height from geopotential.

Parameters

z (number, ndarray or Fieldset) – geopotential (m2/s2)

Return type

same type as z

The computation of geometric height is based on the following formula:

\[h = \frac{R \frac{z}{g}}{R - \frac{z}{g}}\]

where:

  • R is the radius of the Earth (6378388 m)

  • g is the gravitational acceleration (9.81 m/s2)

When a Fieldset returned the ecCodes paramIds of the resulting fields are set to 3008 (geometric height).
