Quality Assessment
Comment
The daily or monthly means do not reveal any obvious reference level shifts.
The data for 1996-2000 were supplied with heights relative to MLLW. Consequently 3015mm was added to refer the data to tide gauge zero.
The data for 1998-2000 were supplied in non-GMT format and had to be shifted into GMT.
