    • Blue intensity from a tropical conifer’s annual rings for climate reconstruction : an ecophysiological perspective 

      Buckley, Brendan M.; Hansen, Kyle G.; Griffin, Kevin L.; Schmiege, Stephanie; Oelkers, Rose; D’Arrigo, Rosanne D.; Stahle, Daniel K.; Davi, Nicole; Nguyen, Tran Quoc Trung; Le, Canh Nam; Wilson, Rob J. S. (2018-08) - Journal article
      We developed Blue Intensity (BI) measurements from the crossdated ring sequences of Fokienia hodginsii (of the family Cupressaceae) from central Vietnam. BI has been utilized primarily as an indirect proxy measurement of ...
    • Experiments based on blue intensity for reconstructing North Pacific temperatures along the Gulf of Alaska 

      Wilson, Rob; D'Arrigo, Rosanne; Andreu-Hayles, Laia; Oelkers, Rose; Wiles, Greg; Anchukaitis, Kevin; Davi, Nicole (2017-08-16) - Journal article
      Ring-width (RW) records from the Gulf of Alaska (GOA) have yielded a valuable long-term perspective for North Pacific changes on decadal to longer timescales in prior studies but contain a broad winter to late summer ...
    • Last millennium northern hemisphere summer temperatures from tree rings : Part I: The long term context 

      Wilson, Rob; Anchukaitis, Kevin; Briffa, Keith R.; Büntgen, Ulf; Cook, Edward; D'Arrigo, Rosanne; Davi, Nicole; Esper, Jan; Frank, Dave; Gunnarson, Björn; Hegerl, Gabi; Helama, Samuli; Klesse, Stefan; Krusic, Paul J.; Linderholm, Hans W.; Myglan, Vladimir; Osborn, Timothy J.; Rydval, Miloš; Schneider, Lea; Schurer, Andrew; Wiles, Greg; Zhang, Peng; Zorita, Eduardo (2016-02-15) - Journal item
      Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have been progressively improved over the last 20 years as new datasets have been developed. This paper, and its companion (Part II, ...
    • Last millennium Northern Hemisphere summer temperatures from tree rings : part II, spatially resolved reconstructions 

      Anchukaitis, Kevin J.; Wilson, Rob; Briffa, Keith R.; Büntgen, Ulf; Cook, Edward R.; D'Arrigo, Rosanne; Davi, Nicole; Esper, Jan; Frank, David; Gunnarson, Björn E.; Hegerl, Gabi; Helama, Samuli; Klesse, Stefan; Krusic, Paul J.; Linderholm, Hans W.; Myglan, Vladimir; Osborn, Timothy J.; Zhang, Peng; Rydval, Miloš; Schneider, Lea; Schurer, Andrew; Wiles, Greg; Zorita, Eduardo (2017-05-01) - Journal article
      Climate field reconstructions from networks of tree-ring proxy data can be used to characterize regional-scale climate changes, reveal spatial anomaly patterns associated with atmospheric circulation changes, radiative ...
    • Tree rings reveal globally coherent signature of cosmogenic radiocarbon events in 774 and 993 CE 

      Büntgen, Ulf; Wacker, Lukas; Galván, J.

F. (2018-09-06) - Journal article
      Though tree-ring chronologies are annually resolved, their dating has never been independently validated at the global scale. Moreover, it is unknown if atmospheric radiocarbon enrichment events of cosmogenic origin ...
