cfdm.Bounds


class cfdm.Bounds(properties=None, data=None, source=None, copy=True, _use_data=True)[source]

Bases: cfdm.mixin.netcdf.NetCDFVariable, cfdm.mixin.netcdf.NetCDFDimension, cfdm.mixin.propertiesdata.PropertiesData, cfdm.core.bounds.Bounds

A cell bounds component of a coordinate or domain ancillary construct of the CF data model.

An array of cell bounds spans the same domain axes as its coordinate array, with the addition of an extra dimension whose size is that of the number of vertices of each cell. This extra dimension does not correspond to a domain axis construct since it does not relate to an independent axis of the domain. Note that, for climatological time axes, the bounds are interpreted in a special way indicated by the cell method constructs.

In the CF data model, a bounds component does not have its own properties because they can not logically be different to those of the coordinate construct itself. However, it is sometimes desired to store attributes on a CF-netCDF bounds variable, so it is also allowed to provide properties to a bounds component.

NetCDF interface

The netCDF variable name of the bounds may be accessed with the nc_set_variable, nc_get_variable, nc_del_variable and nc_has_variable methods.

New in version 1.7.0.

Initialization

Parameters:
properties: dict, optional

Set descriptive properties. The dictionary keys are property names, with corresponding values. Ignored if the source parameter is set.

Parameter example:

properties={'standard_name': 'grid_latitude'}

Properties may also be set after initialisation with the set_properties and set_property methods.

data: Data, optional

Set the data. Ignored if the source parameter is set.

The data also may be set after initialisation with the set_data method.

source: optional

Initialize the properties and data from those of source.

copy: bool, optional

If False then do not deep copy input parameters prior to initialization. By default arguments are deep copied.
