Individualistic and Time-Varying Tree-Ring Growth to Climate Sensitivity
The development of dendrochronological time series in order to analyze climate-growth relationships usually involves first a rigorous selection of trees and then the computation of the mean tree-growth measurement series. This study suggests a change in the perspective, passing from an analysis of climate-growth relationships that typically focuses on the mean response of a species to investiga...
متن کاملMagnetic record associated with tree ring density: Possible climate proxy
A magnetic signature of tree rings was tested as a potential paleo-climatic indicator. We examined wood from sequoia tree, located in Mountain Home State Forest, California, whose tree ring record spans over the period 600 - 1700 A.D. We measured low and high-field magnetic susceptibility, the natural remanent magnetization (NRM), saturation isothermal remanent magnetization (SIRM), and stabili...
متن کاملClimatic variation and tree-ring structure in conifers: empirical and mechanistic models of tree-ring width, number of cells, cell size, cell-wall thickness and wood density
Variations in tree-ring structure are simulated with (1) an empirical model using monthly climatic data as statistical predictors and (2) a mechanisbc model using daily climatic data as growth limiting conditions. The empirical model calibrates standardized ring-width and density chronologies of tree-rings with monthly temperature, precipitation or Palmer Drought Severity Index. The empirical m...
متن کاملClimate Reconstruction Using Tree-Ring Data
Instrument records from the past 200 years support a scientific consensus that climate is changing Trenberth et al. (2007). What is less clear is how to interpret these changes in an historical context spanning many hundreds, or thousands, or tens of thousands of years. The statistical question is this: how do we quantify and model historical climate without having direct observations beyond th...
