              Refernce Levl: A reference level zero has not been established.
                             However, this segment 2010-2011 appears to be
                             relative to the same undefined zero.
              Comment      : The daily and monthly values do not show any  
                             obvious shifts or trends.  The residuals of
                             the hourly data are noisy.

                             Historic data for Gisborne-A are available 1984-91.
                             No data are available until 2010 due to data 
                             quality issues.

                             Gisborne-A is separate from Gisborne-B since 
                             the reference zero for the latter is unconfirmed.
