cf.DimensionCoordinate.Z¶
-
DimensionCoordinate.Z¶ True if and only if the coordinates are for a CF Z axis.
CF Z axis coordinates are for a vertical axis have one or more of the following:
- The
axisproperty has the value'Z' - Units of pressure (see
cf.Units.ispressurefor details), level, layer, or sigma_level - The
positiveproperty has the value'up'or'down'(case insensitive) - The
standard_nameproperty 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'
Examples: >>> c.Units <CF Units: Pa> >>> c.Z True
>>> c.Units.equivalent(cf.Units('K')) and c.positive == 'up' True >>> c.Z True
>>> c.axis == 'Z' and c.Z True
>>> c.Units <CF Units: sigma_level> >>> c.Z True
>>> c.standard_name 'ocean_sigma_coordinate' >>> c.Z True
