Chapter 5: Interpreting High-Resolution Proxy Climate Data
Figure 5.1: a) Expressed Population Signal (EPS) plot ted as a function of
chronology replication for several example RBAR values. High empirical
signal, i.e. high RBAR, means that fewer sampIes are required to maintain
a high quality chronology.
b) The replication (t') necessary in apart of a chronology to maintain the
SubsampIe Signal Strength above a value of 0.85. Examples are shown for a
range of RBAR values.
