Most of the tree ring data are available from the International Tree-Ring Data Bank. Precipitation-sensitive sites are gridpoint PDSI reconstructions of Cook et al. 1999. Temperature Sensitive Tree-ring sites: Eyak Mt., AK: 60 36' N 145 40' W; Nichawak Mt., AK: 60 15' N 143 58' W; Exit Glacier, AK: 60 12' N 149 35' W; Water Supply, AK: 60 07' N 149 28' W; Ellsworth, AK: 60 05' N 148 58' W; Rock Glacier, AK: 60 04' N 148 50' W; Hemlock Knob, AK: 59 29' N 139 08' W; Verstovia, AK: 57 03' N 135 16' W; Barlow Pass, OR: 45 00' N 121 00' W. Two PDO index reconstruction series and 1900-1997 AD instrumental PDO are presented. The 1790-1979 AD series is based on all 11 tree ring predictors. The 1700-1979 AD series is based on 8 of the predictors which extend to AD 1700. ABSTRACT SUPPLIED BY ORIGINATOR: Decadal-scale oscillatory modes of atmosphere-ocean variability have recently been identified in instrumental studies of the Pacific sector. The regime shift around 1976 is one example of such a fluctuation, which has been shown to have significantly impacted climate and the environment along the coastline of the western N and S Americas. The length of meteorological data for the Pacific and western Americas critically limits analyses of such decadal-scale climate variability. Here we present reconstructions of the annual Pacific Decadal Oscillation (PDO) index based on western North American tree-ring records which account for up to 53% of the instrumental variance and extend as far back as AD 1700. The PDO reconstructions indicate that decadal-scale climatic shifts have occurred prior to the period of instrumental record. Evaluation of temperature and precipitation-sensitive tree-ring series from the northeast Pacific as well as these reconstructions reveals evidence for a shift towards less pronounced interdecadal variability after about the middle 1800s. Our analyses also suggest that sites from both the northeast Pacific coast as well as the subtropical Americas need to be included in proxy data sets used to reconstruct the PDO.
