Multi-Millennial Nevada Precipitation Reconstruction

Summary
Abstract: This data set consists of reconstructed precipitation for Nevada Climate
Division 3, annual July through June. Trees used for the reconstruction are
bristlecone pine from Methuselah Walk, White Mountains, California. These data
are archived with the ITRDB, filenames CA535.crn (standardized chronology) and
CA535.rwl (ringwidth measurements).


An extensive network of tree ring chronologies of greater than 1000 years in
length exists for the western United States. This multi-millennial-length tree
ring chronology network provides an excellent opportunity to study decadal to
century scale variability in pre-instrumental times. There are now 80 long
chronologies available that are sensitive to a wide variety of environmental
variables, including warm season temperature and winter precipitation.

In this study, 7979 years of annual (July-June) precipitation were
reconstructed from bristlecone pine in the White Mountains of eastern
California. The reconstruction documents the occurrence of eight multi-decadal
droughts, with the two most recent centered on A.D. 924 and A.D. 1299. The
occurrence of these two droughts is validated by an independent lake-level
record from the neighboring Sierra Nevada Mountains. Droughts of this
character, were they to occur today, would clearly have a devastating impact.
Future work will focus on expanding the multi-millennial record of drought from
tree rings and determining forcing mechanisms for these droughts.
