Comment on ‘Drought variability in the eastern Australia and New Zealand summer drought atlas (ANZDA, CE 1500–2012) modulated by the Interdecadal Pacific Oscillation’
The study of (Palmer et al 2015 Environ. Res. Lett. 10 124002 ) details a spatial reconstruction of drought across eastern Australia and New Zealand over the last 500 years. The authors used a global 0.5° by 0.5° gridded network of the self-calibrating Palmer drought severity index (scPDSI) spanning...

The authors used a global 0.5° by 0.5° gridded network of the self-calibrating Palmer drought severity index (scPDSI) spanning 1901–2012 as the basis for a nested point-by-point regression to reconstruct austral summer (DJF) scPDSI for this region.

These were the LD summer sea salt (LDsss) series, which is a proxy for Western Pacific sea surface temperature and subtropical eastern Australian rainfall (Vance et al 2013 J.

Sci. 20 1703–17 ), and two Interdecadal Pacific Oscillation (IPO) reconstructions produced using two independent methods, namely the Piece-wise Linear Fit (PLF) and Decision Tree (DT) series (Vance et al 2015 Geophys. Res. Lett. 42 129–37 , 2016 Clim. Past 12 595–610 ). We show that the treatment of the Law Dome LDsss record and the PLF and DT IPO reconstructions mis-characterizes both the utility and targets of the three records.
