Fossil Butte National Monument, Wyoming -WY026 Additional Site Information Ed Cook, Dave Meko, Kaimei Dai Purpose of Collection: Climatology - PDSI/PHDI analysis Cores located at the Laboratory of Tree-Ring Research, University of Arizona. Contact David Meko for access. Sample size in .crn file is the number of trees rather than the number of cores in a given year. Core indices computed as the ratio of ringwidth to fitted trend line. Core indices averaged to to form tree indices. Tree indices averaged to to form site index. Bi-weight mean used if 6 or more trees in a given year. Otherwise chron computed by arithmetic mean. Residual chron computed likewise, except from autoregressive residuals of core indices. All ringwidth series used in chronology are listed in table below, with sufficient information to allow independent researcher to duplicate construction of site chronology from the ringwidths in the .rwl file N Core Fit Period Curve fit Persistence 1 FBN10A 1781 1998 NE AR(1) 0.23 2 FBN1A 1866 1998 CS(119 yr) AR(1) 0.16 3 FBN2A 1911 1998 SL AR(1) 0.57 4 FBN3A 1623 1998 SL AR(3) 0.31 5 FBN3B 1680 1998 * CS(235 yr) AR(3) 0.38 6 FBN4A 1566 1998 NE AR(2) 0.33 7 FBN4B 1625 1998 CS(186 yr) AR(2) 0.37 8 FBN4C 1764 1998 CS(118 yr) AR(2) 0.34 9 FBN4D 1736 1998 CS(131 yr) AR(3) 0.47 10 FBN5A 1562 1998 CS(308 yr) AR(3) 0.38 11 FBN5B 1562 1998 NE AR(3) 0.36 12 FBN6A 1594 1998 CS(162 yr) AR(2) 0.43 13 FBN6B 1591 1998 CS(163 yr) AR(2) 0.36 14 FBN6C 1586 1998 CS(82 yr) AR(2) 0.31 15 FBN7A 1480 1998 CS(155 yr) AR(3) 0.32 16 FBN7B 1609 1998 CS(117 yr) AR(2) 0.33 17 FBN8A 1580 1998 * CS(327 yr) AR(2) 0.42 18 FBN8B 1492 1998 CS(356 yr) AR(2) 0.34 19 FBN9A 1654 1998 CS(208 yr) AR(3) 0.36 20 FBN9B 1657 1998 CS(103 yr) AR(3) 0.31 Fit Period = period of ring width used in curve fitting * = differs from full available period of ring width data Curve Fit = type of model used to detrend ring width NE=modified negative exponential SL=least-square-fit straight line HL=horizontal line at mean of ring width for fit period CS=cubic smoothing spline (Wavelength of 50?requency reponse in parentheses) Persistence = autoregressive prewhitening information AR(q) = order q of autoregressive model fit to core index nn = decimal proportion of core-index variance due to persistence; computed as 1-R, where R is the ratio of variance of residual index to variance of standard index COFECHA output: Chronology file name : WY026.CRN Measurement file name : WY026.RWL Date checked : 13APR05 Checked by : H.
