                    Hourly : Cosine-Lanczos filter with cutoff of 120 min. 
                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data        
                             with respective periods of the 95, 50, and 5%      
                             amplitude points at 124.0, 60.2, and 40.2 hours    
                    Monthly: Simple average of all daily values; calculated if  
                             7 or fewer days are missing

              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 future data
                             will be in a separate series.
