geocat.comp.interpolation.pressure_at_hybrid_levels(psfc, hya, hyb, p0=100000.0)#

Pressure at the hybrid levels.

\[p(k) = hya(k) * p0 + hyb(k) * psfc\]

Parameters:

psfc (xarray.DataArray, numpy.ndarray) – A multi-dimensional array of surface pressures (Pa)
hya (xarray.DataArray, numpy.ndarray) – An array of the hybrid A coefficients. Must be 1D if type numpy.ndarray (unitless).
hyb (xarray.DataArray, numpy.ndarray) – An array of the hybrid B coefficients. Must be same type and length as hya and be 1D if type numpy.ndarray (unitless)
p0 (float, optional) – Scalar numeric value equal to surface reference pressure (Pa). Defaults to 100000 Pa.

Returns:

output (xarray.DataArray) – Computed pressure at the provided hybrid levels (Pa)
