xarray.core.resample.DatasetResample¶

class xarray.core.resample.DatasetResample(*args, dim=None, resample_dim=None, **kwargs)

DatasetGroupBy object specialized to resampling a specified dimension

__init__(*args, dim=None, resample_dim=None, **kwargs)

Create a GroupBy object

Parameters
objDataset or DataArray

Object to group.

groupDataArray

Array with the group values.

squeezeboolean, optional

If “group” is a coordinate of object, squeeze controls whether the subarrays have a dimension of length 1 along that coordinate or if the dimension is squeezed out.

grouperpd.Grouper, optional

Used for grouping values along the group array.

binsarray-like, optional

If bins is specified, the groups will be discretized into the specified bins by pandas.cut.

restore_coord_dimsbool, optional

If True, also restore the dimension order of multi-dimensional coordinates.

cut_kwargsdict, optional

Extra keyword arguments to pass to pandas.cut

Methods

 __init__(*args[, dim, resample_dim]) Create a GroupBy object all([dim]) Reduce this DatasetResample’s data by applying all along some dimension(s). any([dim]) Reduce this DatasetResample’s data by applying any along some dimension(s). apply(func[, args, shortcut]) Apply a function over each Dataset in the groups generated for resampling and concatenate them together into a new Dataset. argmax([dim, skipna]) Reduce this DatasetResample’s data by applying argmax along some dimension(s). argmin([dim, skipna]) Reduce this DatasetResample’s data by applying argmin along some dimension(s). Return values of original object at the new up-sampling frequency; essentially a re-index with new times set to NaN. assign(**kwargs) Assign data variables by group. assign_coords(**kwargs) Assign coordinates by group. backfill([tolerance]) Backward fill new values at up-sampled frequency. bfill([tolerance]) Backward fill new values at up-sampled frequency. count([dim]) Reduce this DatasetResample’s data by applying count along some dimension(s). ffill([tolerance]) Forward fill new values at up-sampled frequency. fillna(value) Fill missing values in this object by group. first([skipna, keep_attrs]) Return the first element of each group along the group dimension interpolate([kind]) Interpolate up-sampled data using the original data as knots. last([skipna, keep_attrs]) Return the last element of each group along the group dimension max([dim, skipna]) Reduce this DatasetResample’s data by applying max along some dimension(s). mean([dim, skipna]) Reduce this DatasetResample’s data by applying mean along some dimension(s). median([dim, skipna]) Reduce this DatasetResample’s data by applying median along some dimension(s). min([dim, skipna]) Reduce this DatasetResample’s data by applying min along some dimension(s). nearest([tolerance]) Take new values from nearest original coordinate to up-sampled frequency coordinates. pad([tolerance]) Forward fill new values at up-sampled frequency. prod([dim, skipna]) Reduce this DatasetResample’s data by applying prod along some dimension(s). reduce(func[, dim, keep_attrs]) Reduce the items in this group by applying func along the pre-defined resampling dimension. std([dim, skipna]) Reduce this DatasetResample’s data by applying std along some dimension(s). sum([dim, skipna]) Reduce this DatasetResample’s data by applying sum along some dimension(s). var([dim, skipna]) Reduce this DatasetResample’s data by applying var along some dimension(s). where(cond[, other]) Return elements from self or other depending on cond.
