**What it does**

Select a variable ans can restrict over any of its dimension and apply a scaling (1 by default).
the result is stored in a new netCDF file.
One can also select the range of time (for timeseries) to apply these operations over the range only
when a range of time is selected and when scaling, one can choose to save the entire timeseries or
the selected range only.
when scaling, one can add additional filters on dimensions (typically used to filter 
over latitudes and longitudes)

The xarray select tool can be used after the xarray Info and xarray Coord.
