polaris.ocean.vertical.ztilde.pressure_from_z_tilde

polaris.ocean.vertical.ztilde.pressure_from_z_tilde(z_tilde: DataArray) → DataArray[source]

Convert pseudo-height to sea pressure.

p = -z_tilde * (rho0 * g)

Parameters:: z_tilde (xarray.DataArray) – Pseudo-height in meters (m), positive upward.
Returns:: xarray.DataArray – Sea pressure with the same shape and coords as z_tilde (Pa).
