                    Hourly : 3-point Hanning filter centered on the hour
                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data

                    Monthly: Simple average of all daily values; calculated if  
                             7 or fewer days are missing

              Comment      : The daily  and monthly means reveal no apparent
                             changes in the reference level.  This series is
                             distinguished from Catalina-A due to a level shift
                             of about 40 cm in October 1979.  Timing is poor
                             at times.
