    "The power of xarray comes with the close association of data with coordinates. So it is possible to use the equivalent `.sel` operator but with coordinate values. For example, to select an area that includes the Indian Ocean and Australia use `slice` to indicate the range of latitude and longitude values required and pass as key/value pairs to `sel`.  `slice` will include coordinate values less than **or equal** to the upper bound, not like `range` in basic python that excludes the upper bound"
