Droughts, Pluvials, and Wet Season Timing Across the Chao Phraya River Basin: A 254‐Year Monthly Reconstruction From Tree Ring Widths and δ18O

open access: yesGeophysical Research Letters, Volume 49, Issue 17, 16 September 2022., 2022
Abstract Water system operations require subannual streamflow data—e.g., monthly or weekly—that are not readily achievable with conventional streamflow reconstructions from annual tree rings. This mismatch is particularly relevant to highly seasonal rivers such as Thailand's Chao Phraya. Here, we combine tree ring width and stable oxygen isotope ratios

In Memoriam: Keith R. Briffa, 1952–2017 [PDF]

open access: yes, 2018
Keith R. Briffa was one of the most influential palaeoclimatologists of the last 30 years. His primary research interests lay in Late-Holocene climate change with a geographical emphasis on northern Eurasia.

Scrutinizing tree‐ring parameters for Holocene climate reconstructions

open access: yesWIREs Climate Change, Volume 13, Issue 4, July/August 2022., 2022
Abstract Independent evidence from Europe and Asia shows that tree‐ring stable isotopes can reveal persistent long‐term hydroclimate trends that are generally not captured by more traditional dendroclimatic studies using tree‐ring width or density. Since the recently observed long‐term discrepancy between flatter “growth‐dependent” and more varying ...

The 225-year precipitation variability inferred from tree-ring records in Shanxi Province, the North China, and its teleconnection with Indian summer monsoon [PDF]

open access: yes, 2015
Understanding the interactions between the East Asian summer monsoon and Indian summer monsoon is a challenging task because of the insufficient proxy records.

Evaluation of Different Pooling Methods to Establish a Multi-Century δ18O Chronology for Paleoclimate Reconstruction

open access: yesGeosciences, 2019
To develop multi-century stable isotope chronologies from tree rings, pooling techniques are applied to reduce laboratory costs and time. However, pooling of wood samples from different trees may have adverse effects on the signal amplitude in the final ...

Topographic influences on ring widths of trees and shrubs across alpine treelines in southwest Yukon

open access: yesArctic, Antarctic, and Alpine Research, 2018
Growth responses of trees and shrubs to climate often exhibit unexplained variation in alpine regions, making it difficult to predict how they will respond to future changes in climate.

Comparison of the Responses of Radial Growth to Climate Change for Two Dominant Coniferous Tree Species in the Guancen Mountain, North-Central China

open access: yesEnvironmental Sciences Proceedings, 2022
The radial growth of coniferous trees in the mid–high latitudes of the Northern Hemisphere has an unstable response to climate warming. We analyzed the differences in the radial growth patterns of the two dominant species (Larix principis-rupprechtii ...

Detrending ability of several regression equations in tree-ring research: a case study based on tree-ring data of Norway spruce (Picea abies [L.])

open access: yesJournal of Forest Science, 2011
The aim of this study was to investigate tree-ring width variability and to distinguish groups of trees with similar growth trends in order to study tree growth responses to various stand and site conditions. The methods of cluster analysis were employed
