Spanish Conquest Drought 1521-1524
Welcome to the Mexican Drought Atlas. This web application
provides access to summer (June-August) reconstructions of the self-calibrating
Palmer Drought Severity Index (PDSI) on a 0.5° latitude/longitude grid centered
over Mexico from AD 1400-2012. The reconstructions are derived from 252 tree-ring
chronologies over subtropical North America. For further details on the
reconstructions, see Stahle et al. (2016, 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 1400-2012 is available via the link below.
Questions, comments, or suggestions may be sent to Dorian J. Burnette.
