                             The A.OTT gauge was removed and replaced in 2014
                             with a Kalesto radar gauge.  The reference level
                             (zero of series) have not been linked so the sets
                             are kept as 281A (1954-2006) and 281B (2014-).

              Comment      :    The data contain significant fluctuations with
                             periods of one to ten days mostly due to oceanic
                             variability on the continental shelf.  The data
                             set is of high quality with no obvious reference
                             level shifts.
