                    Hourly : Cosine-Lanczos filter with cutoff of 120 min. 
                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data

                    Monthly: Simple average of all daily values; calculated if

              Comment      : The gauge at Jackson was destroyed by fire in 
                             2012 and re-installed in 2013.  The height of the
                             original gauge was not surveyed so the new station
                             is stored in a separate series.
