Quality Assessment by the UH Sea Level Centre

Comments

  • The daily and monthly means reveal no apparent changes in the reference level and agree with nearest stations Rabaul and Nauru.

  • The daily means and the hourly residuals show significant fluctuations with a duration of around a day associated with westerly winds.

  • The timing accuracy is no better than plus or minus 8 minutes prior to 1985.

  • Silting around the stilling wells caused questionable fluctuations during 1987 - 1990.
