cf.Bounds.Z

Bounds.Z

True if and only if the data are coordinates for a CF ‘Z’ axis.

CF ‘Z’ axis coordinates are defined by having one or more of the following:

  • The axis property has the value 'Z'

  • Units of pressure, level, layer or sigma_level

  • The positive property has the value 'up' or 'down' (case insensitive)

  • The standard_name property is one of 'atmosphere_ln_pressure_coordinate', 'atmosphere_sigma_coordinate', 'atmosphere_hybrid_sigma_pressure_coordinate', 'atmosphere_hybrid_height_coordinate', 'atmosphere_sleve_coordinate’, 'ocean_sigma_coordinate', 'ocean_s_coordinate', 'ocean_s_coordinate_g1', 'ocean_s_coordinate_g2', 'ocean_sigma_z_coordinate' or 'ocean_double_sigma_coordinate'
