The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Bhutan, Southcentral Asia. The time period coverage is from 207 to -61 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. 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.

IITRDB27 ABSTRACT SUPPLIED BY ORIGINATOR: We developed a 50-year tree ring d18O chronology for each of three tree species (Juniperus indica, Larix griffithii, and Picea spinulosa) using a total of 12 trees (four trees per species) from the Bhutan Himalaya. Despite originating from different species sampled at two different altitudes, the d18O chronologies are highly correlated with one another (r = 0.76-0.89). Response analyses reveal that tree ring d18O values are controlled mainly by summer precipitation, irrespective of species. Based on these results, a robust 269-year d18O chronology was established to reconstruct the amount of May-September precipitation based on data from four larch trees. Our tree ring d18O data show significant correlations with those from other regions of the Himalaya and the Tibetan Plateau, indicating that common signals related to monsoon activity are recorded in the data. However, at centennial timescales, our data from Bhutan show normal conditions during the 20th century, whereas records from sites in western Nepal and the southern/eastern Tibetan Plateau show weakening trends in monsoon intensity during the last 100-200 years; the weakening trends may be the result of a reduction in the meridional sea surface temperature gradient in the Indian Ocean during this time. At continental scales, the tree ring records show that areas more from ocean basins are particularly sensitive to reduced monsoon circulation. Correlation analyses suggest that the El Niño-Southern Oscillation (ENSO) plays an important role in modulating summer precipitation. However, the teleconnected relationship disappears during the period 1951-1970, coinciding with a negative phase of the Pacific Decadal Oscillation (PDO), implying interdecadal modulation of the PDO on the influence of the ENSO on precipitation in Bhutan.
