polaris.ocean.vertical.ztilde.z_tilde_from_pressure

polaris.ocean.vertical.ztilde.z_tilde_from_pressure(p: DataArray) → DataArray

Convert sea pressure to pseudo-height.

z_tilde = -p / (rho0 * g)

Parameters:

p (xarray.DataArray) – Sea pressure in Pascals (Pa).

Returns:

xarray.DataArray – Pseudo-height with the same shape and coords as p (units: m).
