In addition, 73 proxy records were assembled in collaboration with Chinese and international scholars, from 27 publically available proxy records and 40 tree-ring chronologies that are not available in public datasets. These records were used to reconstruct annual mean temperature variability in the West Qinling Mountains over the past 500 years (AD 1500-1995), using a modified point-by-point regression (hybrid PPR) method. The results demonstrate that the hybrid PPR method successfully integrates the temperature signals from different types of proxies, and that the method preserves a high degree of low-frequency variability. The reconstruction shows greater temperature variability in the West Qinling Mountains than has been found in previous studies. Our temperature reconstruction for this region shows: 1) five distinct cold periods, at approximately AD 1520-1535, AD 1560-1575, AD 1610-1620, AD 1850-1875 and AD 1965-1985, and four warm periods, at approximately AD 1645-1660, AD 1705-1725, AD 1785-1795 and AD 1920-1945; 2) that in this region, the 20th century was not the warmest period of the past 500 years; and 3) that a dominant and persistent oscillation of ca. 64 years is significantly identified in the 1640-1790 period.\r\n","author":null,"citation":"Fengmei Yang, Naiang Wang, Feng Shi, Fredrik Charpentier Ljungqvist, Shigong Wang, Zexin Fan, Junwei Lu. 2013. \r\nMulti-Proxy Temperature Reconstruction from the West Qinling Mountains, China, for the Past 500 Years. \r\nPLOS One, Vol. 8 (2), e57638. \r\nDOI: 10.1371/journal.pone.0057638","edition":null,"identifier":{"id":"10.1371/journal.pone.0057638","type":"doi","url":"http://dx.doi.org/10.1371/journal.pone.0057638"},"issue":null,"journal":"PLoS ONE","pages":null,"pubRank":"1","pubYear":2013,"reportNumber":null,"title":"Multi-Proxy Temperature Reconstruction from the West Qinling Mountains, China, for the Past 500 Years","type":"publication","volume":null}],"reconstruction":"Y","scienceKeywords":["Air Temperature Reconstruction"],"site":[{"NOAASiteId":"54490","geo":{"geoType":"Feature","geometry":{"coordinates":["33","35","102","105"],"type":"POLYGON"},"properties":{"easternmostLongitude":"105","maxElevationMeters":null,"minElevationMeters":null,"northernmostLatitude":"35","southernmostLatitude":"33","westernmostLongitude":"102"}},"locationName":"Continent>Asia>Eastern Asia>China","mappable":"N","paleoData":[{"NOAADataTableId":"23560","coreLengthMeters":null,"dataFile":[{"NOAAKeywords":["earth science>paleoclimate>reconstructions>air temperature"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/yang2013/west-qinling2013.txt","linkText":"West Qinling Mountains Temperature Reconstruction","urlDescription":"Text Data File","variables":[{"cvAdditionalInfo":null,"cvDataType":"CLIMATE RECONSTRUCTIONS","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":null,"cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"year Common Era","cvWhat":"age variable>age"},{"cvAdditionalInfo":null,"cvDataType":"CLIMATE RECONSTRUCTIONS","cvDetail":"anomalized","cvError":null,"cvFormat":"Numeric","cvMaterial":"reconstruction material>multiple proxies","cvMethod":null,"cvSeasonality":"annual","cvShortName":null,"cvUnit":"degree Celsius","cvWhat":"earth system variable>temperature variable>temperature>surface temperature"},{"cvAdditionalInfo":null,"cvDataType":"CLIMATE RECONSTRUCTIONS","cvDetail":"anomalized","cvError":"range lower bound","cvFormat":"Numeric","cvMaterial":"reconstruction material>multiple proxies","cvMethod":null,"cvSeasonality":"annual","cvShortName":null,"cvUnit":"degree Celsius","cvWhat":"earth system variable>temperature variable>temperature>surface temperature"},{"cvAdditionalInfo":null,"cvDataType":"CLIMATE RECONSTRUCTIONS","cvDetail":"anomalized","cvError":"range upper bound","cvFormat":"Numeric","cvMaterial":"reconstruction material>multiple proxies","cvMethod":null,"cvSeasonality":"annual","cvShortName":null,"cvUnit":"degree Celsius","cvWhat":"earth system variable>temperature variable>temperature>surface temperature"}]},{"NOAAKeywords":["earth science>paleoclimate>reconstructions>air temperature"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/yang2013/west-qinling2013.xls","linkText":"West Qinling Mountains Temperature Reconstruction","urlDescription":"Excel Data File","variables":[]}],"dataTableName":"WestQinling2013temp","dataTableNotes":null,"earliestYear":1500,"earliestYearBP":450,"earliestYearCE":1500,"mostRecentYear":1995,"mostRecentYearBP":-45,"mostRecentYearCE":1995,"species":[],"timeUnit":"AD"}],"siteName":"West Qinling Mountains"}],"studyCode":null,"studyName":"West Qinling Mountains 500 Year Multiproxy Temperature Reconstruction","studyNotes":"Data from Fig.5A Yang et al. 2013.
