The dating process consists of comparing the sequence of tree ring widths in the sample to a dated master sequence. Springer, Berlin, Heidelberg In dendrochronology wood samples are dated according to the tree rings they contain.

The Tropical Rainfall Index (TRI) correlates well with instrumental and reconstructed winter precipitation (r = 0.49 and 0.55, respectively), reflecting the strong ENSO modulation of cool season climate over northern Mexico.

Up to three tree-ring samples may be viewed and compared on the basic graphic screen at a time.

Tree-ring samples may consist of hundreds of ring width measurements.
