Unified ENSO Proxy (UEP)
The UEP consolidates the information contained in 10 previously defined ENSO reconstructions (Dunbar et al. 1994; Stahle et al. 1998; Cook 2000; Mann et al 2000; Evans et al. 2001; Evans et al. 2002; Cobb et al. 2003; Cook 2008; Braganza et al. 2009) into one unified proxy that captures the joint features of the input reconstructions. The time series represents annual (July-June) average index of ENSO activity for the period 1650-1977.
This is the 13-year low-pass filtered variability of the UEP (described above). This time series represents Pacific Decadal Oscillation (PDO) and Interdecadal Pacific Oscillation (IPO) -like multi-decadal variability for the period 1650-1977.
