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'
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
