LIST OF FILES: readme.hughes96.txt (this file), 
mwkreconraw.dat (reconstructed precipitation),
mwkreconfilt.dat (reconstructed precipitation smoothed 
with a bidecadal Gaussian filter).

DESCRIPTION:
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).  

Data Files:
mwkreconraw.dat = the 8000 year reconstruction of annual (July-June)
precipitation in cm for Nevada Division 3.

mwkreconfilt.dat = the same data, smoothed with a bidecadal Gaussian
filter.
