The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Pakistan, Southcentral Asia. The time period coverage is from 400 to -67 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.

ABSTRACT SUPPLIED BY ORIGINATOR: Currently, the rate of global warming has led to persistent drought patterns. It is considered to be the preliminary reason affecting socio-economic development under the background of dynamic forecasting of water supply and forest ecosystems in West Asia. However, long-term climate records in the semi-arid Chitral mountains of northern Pakistan are seriously lacking. Therefore, we developed a new tree-ring width chronology of Cedrus deodara spanning the period of 1537-2017. We reconstructed the March-August Palmer Drought Sensitivity Index (PDSI) for the past 424 years back to A.D. 1593. Our reconstruction was featured with nine dry and eight wet periods 1593-1598, 1602-1608, 1631-1645, 1647-1660, 1756-1765, 1785-1800, 1870-1878, 1917-1923, 1981-1995, and 1663-1675, 1687-1708, 1771-1773, 1806-1814, 1844-1852, 1932-1935, 1965-1969 and 1996-2003, respectively. This reconstruction is consistent with other dendroclimatic reconstructions in west Asia, confirming its reliability. The analysis of the Multi-Taper Method and wavelet analysis revealed drought variability at periodicities of 2.1-2.4, 3.3, 6, 16.8, and 34-38 years. The drought patterns could be linked to the broad-scale atmospheric-oceanic variability such as El Niño-Southern Oscillation (ENSO), Atlantic Multi-decadal Oscillation (AMO) and solar activity. In terms of current climate conditions, our findings have important implications for developing drought-resistant policies in communities on the fringes of Hindu Kush mountain Ranges in northern Pakistan.
