ufs2arco.Layers2Pressure.calc_geopotential#

Layers2Pressure.calc_geopotential(hgtsfc: DataArray, delz: DataArray) → DataArray#

Compute geopotential field

Note

If delz is computed by calc_delz(), then a hydrostatic approximation is used. This may be inconsistent with the original simulation/dataset.

Parameters:

  • hgtsfc (xr.DataArray) – surface/orographic height, and vertical layer thickness

  • delz (xr.DataArray) – surface/orographic height, and vertical layer thickness

Returns:

geopotential (xr.DataArray) – height in [m^2 / s^2] (i.e. height * gravity)
