Experiments based on blue intensity for reconstructing North Pacific temperatures along the Gulf of Alaska [PDF]

open access: yesClimate of the Past, 2017
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 seasonal climate response.

Accelerated Recent Warming and Temperature Variability Over the Past Eight Centuries in the Central Asian Altai From Blue Intensity in Tree Rings

open access: yesGeophysical Research Letters, 2021
Warming in Central Asia has been accelerating over the past three decades and is expected to intensify through the end of this century. Here, we develop a summer temperature reconstruction for western Mongolia spanning eight centuries (1269–2004 C.E ...

Revised Computer Programs for Tree-Ring Research

open access: yes, 1979
Three computer programs that are basic to the processing and development of tree -ring chronologies are now available. They were designed to refine and replace older programs that were previously furnished by the laboratory.

Identifying Low-Frequency Tree-Ring Variation

open access: yes, 1991
I propose an approach to provide 95% confidence intervals for a chronology of low-frequency tree-ring variation so that a level of significance or importance for trends can be inferred.

Ecological and societal effects of Central Asian streamflow variation over the past eight centuries

open access: yesnpj Climate and Atmospheric Science, 2022
Understanding changes in water availability is critical for Central Asia; however, long streamflow reconstructions extending beyond the period of instrumental gauge measurements are largely missing.

IntCal20 Tree Rings: An Archaeological Swot Analysis [PDF]

open access: yesRadiocarbon, 2020
ABSTRACTWe undertook a strengths, weaknesses, opportunities, and threats (SWOT) analysis of Northern Hemisphere tree-ring datasets included in IntCal20 in order to evaluate their strategic fit with the demands of archaeological users. Case studies on wiggle-matching single tree rings from timbers in historic buildings and Bayesian modeling of series of

Central Asia daily extreme precipitation in observations and gridded datasets: A threshold criteria perspective

open access: yesFrontiers in Environmental Science, 2022
The extreme precipitation threshold is fundamental to extreme precipitation research, directly affecting the cognition of extreme characteristics. Based on the daily precipitation data of 62 meteorological stations from 1985 to 2005, this study uses ...

Tree-Ring Skeleton Plotting by Computer

open access: yes, 1979
Skeleton plotting is an established manual technique for representing the relative narrowness of tree rings in a single radius. These plots can be used as a visual aid to crossdating.

Climate Change in the Eastern Xinjiang of China and Its Connection to Northwestern Warm Humidification

open access: yesAtmosphere, 2023
Eastern Xinjiang, as a typical extremely arid area, exhibits a high sensitivity to climate change. Gaining a comprehensive understanding of the climatic changes in this region, along with their driving mechanisms, and comparing these with the broader ...
