Trans. : No Distribution : 1988-2014 Refernce Levl: All heights have been referred to the station tide staff zero which is linked to fixed bench marks. A link has not been made to the historic series Talara-A. The time period 1970-1987 has numerous level shifts per year. These years are not available in the public archive until resolved. The level stability for 1988-2001 is better although some uncertainty exists for select time spans, such as 25 Oct 1988 - 03 Feb 1989 (low by 150 mm), 03 Feb - 30 Mar 1989 (high by 100 mm), and 27 May - 09 Sep 1992 (low by 100 mm). These suspicious levels were highlighted by plots of the hourly residuals and differences in daily means between La Libertad, Los Lobos, and Callao. Comment : The series has numerous data gaps and poor timing through most of the record although the data quality improves starting in 1995.
