The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Yukon Territory, Canada. The time period coverage is from 307 to -63 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.\r\n \r\n \r\n Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

The resulting chronology spanned the period from AD 1763 to 2013. A polynomial regression (R = 0.720, p < 0.001) indicated that the pre-1840 segment of the chronology had below-normal tree ring-width index (RWI) values (average 0.64, with modest variation), but the subsequent segment had greater variation and a steady increase in RWI values (average 0.89) until ~1920. After 1930, RWI values began to increase again (average 1.06) with 51% more variation than had previously occurred. Peak RWI values after 1930 were double those of the early 1800s. RWI values were uncorrelated with air temperature variables (except September minima), but weakly and positively correlated (r < 0.35) with precipitation variables. RWI values were moderately correlated with annual heat-moisture index values (r = -0.415, p < 0.001), although more strongly with RWI values less than 1.1 (R = -0.631, p < 0.001). Therefore, the RWI chronology was interpreted from an ecological moisture-balance perspective, with possible long-term temperature changes estimated from archival sources. The latter suggested a 2.1 - 3.1C rise since the early 1800s. Extreme RWI values and portions of the chronology were associated with known environmental events.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n distributor\r\n \r\n \r\n \r\n \r\n \r\n \r\n In most cases, electronic downloads of the data are free.
