code: def stations(self, *stns):
          
          self._set_query(self.spatial_query, stn=stns)
          return self
docs: Specify one or more stations for the query.
  
          This modifies the query in-place, but returns `self` so that multiple
          queries can be chained together on one line.
  
          This replaces any existing spatial queries that have been set.
  
          Parameters
          ----------
          stns : one or more strings
              One or more names of variables to request
  
          Returns
          -------
          self : RadarQuery
              Returns self for chaining calls
