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 19...

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 19012012 as the basis for a nested point-by-point regression to reconstruct austral summer (DJF) scPDSI for this region. Their study used 176 tree rings from New Zealand, Indonesia and Australia, and one coral record from the Great Barrier Reef. In their paper Palmer et al (2015) compared three publically available proxy records and reconstructions derived from the Law Dome ice core (East Antarctica) to their reconstructed scPDSI.
