                             zero, which is linked to land-based benchmarks. 
                             This reference zero is unique to this station and
                             is not an official datum (chart, national, etc.) 
                             and is not relative to local tidal parameters, 
                             such as mean lower low water.  See the Originators
                             for benchmark descriptions, maps, and the geodetic
                             levelling history.
              Comment      : 087A and 087B are separate because they do not
                             related to the same reference level zero.

                             The daily values difference between Quepos-B and
                             Acajutla-C suggests a 30 mm jump May 2015-Sep 2017.
                             However the difference with La Libertad and Santa
                             Cruz do not show a jump.  AVISO for this period are
                             not available for the Quepos area.  It is assumed
                             the Quepos-B data are good.
