Quality Assessment by the UH Sea Level Center
Comment: The daily and monthly means do not reveal any reference level shifts or trends upto the end of 1991. Data from Diego Garcia-B and Diego Garcia-D are maintained in separate records because these series are not linked to the same tide staff zero. Timing errors are evident in the hourly data.
