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

              Refernce Levl: The data are referred to the tide gauge zero 
                             which has not been linked to fixed bench marks.
              Comment      : This short record is part of the set of 
                             observations taken at San Martin by AWI:
                             681A: 21 Jan 1995 - 18 Feb 1995
                             681B: 22 Jan 1998 - 09 Feb 1998
                             681C: 09 Feb 1998 - 09 Feb 1999
                             The reference level of each series is independent.
                             The data are not linked fixed benchmarks.
                             
                             The timing of the data is good.
