class cf.RaggedIndexedContiguousArray(compressed_array=None, shape=None, size=None, ndim=None, count_variable=None, index_variable=None)

Bases: cf.data.abstract.compressedarray.CompressedArray, cfdm.data.raggedindexedcontiguousarray.RaggedIndexedContiguousArray

An underlying indexed contiguous ragged array.

A collection of features, each of which is sequence of (vertical) profiles, stored using an indexed contiguous ragged array combines all feature elements along a single dimension (the “sample dimension”) such that a contiguous ragged array representation is used for each profile and the indexed ragged array representation to organise the profiles into timeseries.

The information needed to uncompress the data is stored in a “count variable” that gives the size of each profile; and in a “index variable” that specifies the feature that each profile belongs to.

New in version 3.0.0.

Initialization

Parameters:

compressed_array: Data

The compressed array.

shape: tuple

The uncompressed array dimension sizes.

size: int

Number of elements in the uncompressed array.

ndim: int

The number of uncompressed array dimensions

count_variable: Count

The count variable required to uncompress the data, corresponding to a CF-netCDF count variable.

index_variable: Index

The index variable required to uncompress the data, corresponding to a CF-netCDF CF-netCDF index variable.

Inspection

Methods
