Soil Moisture Conditions In 1867
June-August PDSI |
Welcome to the Great Eurasian 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 over the entire Eurasian region and a substantial portion of sub-Saharan Africa from AD
0000-2020. The reconstructions are derived from 1869 tree-ring chronologies and one annually layered speleothem record. For further details on the reconstructions, see Cook et al. (2024, 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 0000-2020 is available via the link below.
