Trans. : No Distribution : 1988-2016 Refernce Levl: All heights have been referred to the station tide staff zero which is linked to fixed bench marks. The following short-lived step function shifts were adjusted based on examination of residuals and daily data of neighboring sites. yyyymmddhh to yyyymmddhh added to original (mm) 1990081417 1990083110 -575 1997010912 1997020212 100 These adjustments are uncertain to a few cm. Series 678B has not been linked to 678A which has a mean level about 30 cm lower. Comment : The difference of daily data with La Libertad, Lobos, and Callao suggest that Jan-Feb 1988 may be about 10 cm low and Jun-Jul 1988 may be about 10 cm high than the long term mean. Difference with AVISO altimeter suggest 2001-2005 is ~10 cm high.
