xarray.Dataset.sum¶
-
Dataset.
sum
(dim=None, skipna=None, **kwargs)¶ Reduce this Dataset’s data by applying sum along some dimension(s).
Parameters: - dim : str or sequence of str, optional
Dimension(s) over which to apply sum. By default sum is applied over all dimensions.
- skipna : bool, 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_count : int, 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_attrs : bool, 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.
- **kwargs : dict
Additional keyword arguments passed on to the appropriate array function for calculating sum on this object’s data.
Returns: - reduced : Dataset
New Dataset object with sum applied to its data and the indicated dimension(s) removed.
