  <Summary>
    <Abstract>Records of past temperature, precipitation, and other climate variables derived from paleoclimate proxies.  Parameter keywords describe what was measured in this data set.  Additional summary information can be found in the abstracts of papers listed in the data set citations. 
          STUDY NOTES: 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.
