Tree-ring drought atlases provide a paleoclimate analog to modern drought indices, most commonly the Palmer Drought Severity Index (PDSI). Produced on a regular lat-lon grid for regions such as North America, Europe, and Australia, these centuries-long datasets are convenient for comparisons with climate model experiments and historical data on human populations…

The width of an annual tree ring is a very simple indicator of the character of that year’s weather, but collectively the global network of tree-ring width measurements represents an invaluable resource for high-resolution paleoclimatology.
