# xarray.core.resample.DataArrayResample.min

#### DataArrayResample.min(dim=None, , skipna=None, keep_attrs=None, \*\*kwargs)[[source]](https://github.com/pydata/xarray/blob/main/xarray/core/_aggregations.py#L8688-L8792)

Reduce this DataArray’s data by applying `min` (i.e., minimum) along some dimension(s).

* **Parameters:**
  * **dim** ([`str`](https://docs.python.org/3/builtins/stdtypes.html#str), `Iterable` of `Hashable`, `"..."` or [`None`](https://docs.python.org/3/builtins/constants.html#None), *default*: [`None`](https://docs.python.org/3/builtins/constants.html#None)) – Name of dimension[s] along which to apply `min`. For e.g. `dim="x"`
    or `dim=["x", "y"]`. If None, will reduce over the Resample dimensions.
    If “…”, will reduce over all dimensions.
  * **skipna** ([`bool`](https://docs.python.org/3/builtins/functions.html#bool) or [`None`](https://docs.python.org/3/builtins/constants.html#None), *optional*) – If True, skip missing values (as marked by NaN). By default, only
    skips missing values for float dtypes; other dtypes either do not
    have a sentinel missing value (int) or `skipna=True` has not been
    implemented (object, datetime64 or timedelta64).
  * **keep_attrs** ([`bool`](https://docs.python.org/3/builtins/functions.html#bool) or [`None`](https://docs.python.org/3/builtins/constants.html#None), *optional*) – If True, `attrs` will be copied from the original
    object to the new one.  If False, the new object will be
    returned without attributes.
  * **\*\*kwargs** (`Any`) – Additional keyword arguments passed on to the appropriate array
    function for calculating `min` on this object’s data.
    These could include dask-specific kwargs like `split_every`.
* **Returns:**
  **reduced** ([`DataArray`](xarray.DataArray.html.md#xarray.DataArray)) – New DataArray with `min` applied to its data and the
  indicated dimension(s) removed

### Notes

Use the `flox` package to significantly speed up resampling computations,
especially with dask arrays. Xarray will use flox by default if installed.
Pass flox-specific keyword arguments in `**kwargs`.
See the [flox documentation](https://flox.readthedocs.io) for more.

```pycon

Use `skipna` to control whether NaNs are ignored.

```pycon
>>> da.resample(time="3ME").min(skipna=False)
<xarray.DataArray (time: 3)> Size: 24B
array([ 1.,  0., nan])
Coordinates:
  * time     (time) datetime64[us] 24B 2001-01-31 2001-04-30 2001-07-31
