Tree ring records provide one of the most important data                   bases for reconstructing past climate variability on time scales                of years to decades.  This project will merge 900 published and                 new tree ring records in a grid covering all regions of the                     continental United States and compare them with the historical                  records of climate from each cell of the grid.  The relationship                between drought occurrence and tree ring growth will be                         determined and used for climate reconstructions back through the                historical record to perhaps the 17th century.                                       The importance of this project is that it will reconstruct                 both the spatial and temporal variability of climate,                           particularly drought occurrence, in North America during the past               three centuries.  It will provide the information needed to                     evaluate the background variability of climate change.  This                    collaborative project includes investigators from the University                of Arizona, the University of Arkansas, and the Lamont-Doherty                  Geological Observatory of Columbia University.
