The Great Drought 1876-1878
June-August PDSI |
Welcome to the Monsoon Asia Drought Atlas. This web
application provides access to summer (June-August) reconstructions of the
self-calibrating Palmer Drought Severity Index (PDSI) on a 2.5°
latitude/longitude grid centered over the Indian, East Asian, and Australian
regions of the Asia monsoon from AD 1300-2005. The reconstructions are derived
from 327 tree-ring
chronologies. For further details on the reconstructions, see Cook et al. (2010, 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 1300-2005 is available via the link below.
Questions, comments, or suggestions may be sent to Dorian J. Burnette.
