xarray.core.resample.DataArrayResample#

class xarray.core.resample.DataArrayResample(*args, dim=None, resample_dim=None, **kwargs)[source]#

DataArrayGroupBy object specialized to time resampling operations over a specified dimension

__init__(*args, dim=None, resample_dim=None, **kwargs)[source]#

Create a GroupBy object

Parameters:
  • obj (Dataset or DataArray) ‚Äď Object to group.

  • grouper (Grouper) ‚Äď Grouper object

  • restore_coord_dims (bool, default: True) ‚Äď If True, also restore the dimension order of multi-dimensional coordinates.

Methods

__init__(*args[, dim, resample_dim])

Create a GroupBy object

all([dim, keep_attrs])

Reduce this DataArray's data by applying all along some dimension(s).

any([dim, keep_attrs])

Reduce this DataArray's data by applying any along some dimension(s).

apply(func[, args, shortcut])

Backward compatible implementation of map

asfreq()

Return values of original object at the new up-sampling frequency; essentially a re-index with new times set to NaN.

assign_coords([coords])

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, keep_attrs])

Reduce this DataArray's data by applying count along some dimension(s).

cumprod([dim, skipna, keep_attrs])

Reduce this DataArray's data by applying cumprod along some dimension(s).

cumsum([dim, skipna, keep_attrs])

Reduce this DataArray's data by applying cumsum 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

map(func[, args, shortcut])

Apply a function to each array in the group and concatenate them together into a new array.

max([dim, skipna, keep_attrs])

Reduce this DataArray's data by applying max along some dimension(s).

mean([dim, skipna, keep_attrs])

Reduce this DataArray's data by applying mean along some dimension(s).

median([dim, skipna, keep_attrs])

Reduce this DataArray's data by applying median along some dimension(s).

min([dim, skipna, keep_attrs])

Reduce this DataArray'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, min_count, keep_attrs])

Reduce this DataArray's data by applying prod along some dimension(s).

quantile(q[, dim, method, keep_attrs, ...])

Compute the qth quantile over each array in the groups and concatenate them together into a new array.

reduce(func[, dim, axis, keep_attrs, ...])

Reduce the items in this group by applying func along some dimension(s).

std([dim, skipna, ddof, keep_attrs])

Reduce this DataArray's data by applying std along some dimension(s).

sum([dim, skipna, min_count, keep_attrs])

Reduce this DataArray's data by applying sum along some dimension(s).

var([dim, skipna, ddof, keep_attrs])

Reduce this DataArray's data by applying var along some dimension(s).

where(cond[, other])

Return elements from self or other depending on cond.

Attributes
