xarray.Dataset.sum

Dataset.sum(dim=None, skipna=None, **kwargs)

Reduce this Dataset’s data by applying sum along some dimension(s).

Parameters

dimstr or sequence of str, optional

Dimension(s) over which to apply sum. By default sum is applied over all dimensions.

skipnabool, 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).

min_countint, default None

The required number of valid values to perform the operation. If fewer than min_count non-NA values are present the result will be NA. New in version 0.10.8: Added with the default being None.

keep_attrsbool, optional

If True, the attributes (attrs) will be copied from the original object to the new one. If False (default), the new object will be returned without attributes.

**kwargsdict

Additional keyword arguments passed on to the appropriate array function for calculating sum on this object’s data.

Returns

reducedDataset

New Dataset object with sum applied to its data and the indicated dimension(s) removed.
