cfdm.core.CellMethod¶

class
cfdm.core.
CellMethod
(axes=None, method=None, qualifiers=None, source=None, copy=True)[source]¶ Bases:
cfdm.core.abstract.container.Container
A cell method construct of the CF data model.
One or more cell method constructs describe how the cell values of the field construct represent the variation of the physical quantity within its cells, i.e. the structure of the data at a higher resolution.
A single cell method construct consists of a set of axes, a “method” property which describes how a value of the field construct’s data array describes the variation of the quantity within a cell over those axes (e.g. a value might represent the cell area average), and descriptive qualifiers serving to indicate more precisely how the method was applied (e.g. recording the spacing of the original data, or the fact that the method was applied only over El Nino years).
New in version (cfdm): 1.7.0
Initialisation
 Parameters
 axes: (sequence of)
str
, optional Set the axes of the cell method construct, specified either by the construct identifiers of domain axis constructs, standard names, or the special string
'area'
.The axes may also be set after initialisation with the
set_axes
method. Parameter example:
axes='domainaxis0'
 Parameter example:
axes=['domainaxis0']
 Parameter example:
axes=('domainaxis0', 'domainaxis1')
 Parameter example:
axes='area'
 Parameter example:
axes=['domainaxis2', 'time']
 method:
str
, optional Set the axes of the cell method construct. Either one or more domain axis construct identifiers or standard names. Ignored if the source parameter is set.
The method may also be set after initialisation with the
set_method
method. Parameter example:
method='mean'
 qualifiers:
dict
, optional Set descriptive qualifiers. The dictionary keys are qualifier names, with corresponding values. Ignored if the source parameter is set.
Qualifiers may also be set after initialisation with the
qualifiers
andset_qualifier
methods. Parameter example:
qualifiers={'comment': 'sampled instantaneously'}
 Parameter example:
qualifiers={'where': 'sea', ''over': 'ice'}
 source: optional
Initialise the axes, method and qualifiers from those of source.
Note that if source is a
CellMethod
instance thencfdm.core.CellMethod(source=source)
is equivalent tosource.copy()
. copy:
bool
, optional If False then do not deep copy input parameters prior to initialisation. By default arguments are deep copied.
