Abstract
Annual tree-ring chronologies from certain well-drained sites in the Hudson Valley of New York record past changes in temperature and precipitation. This information accounts for much of the July variation in Palmer drought severity indices during the period 1931 to 1970 and is used to develop a preliminary reconstruction of drought as long ago as 1728.Year: 1977 PMID: 17809441 DOI: 10.1126/science.198.4315.399
