Settlement Drought 1791-1792
Welcome to the Eastern Australia and New Zealand
Drought Atlas. This web application provides access to the austral summer
(December-February) reconstructions of the self-calibrating Palmer Drought
Severity Index (PDSI) on a 0.5° latitude/longitude grid centered over eastern
Australia and New Zealand from AD 1500-2012. The reconstructions are derived
from 176 tree-ring chronologies and one coral series. For further details on the reconstructions,
see Palmer et al. (2015, link below).
Maps and time series can be created using tools under the "Maps" and "Time
Series" menus, respectively. For details on how to create maps and time series,
see the "Help" menu. An animation that runs through each year of the reconstruction
from AD 1500-2012 is available via the link below.
Questions, comments, or suggestions may be sent to Dorian J. Burnette.
