Feasibility of High-Density Climate Reconstruction Based on Forest Inventory and Analysis (FIA) Collected Tree-ring Data
This study introduces a novel tree-ring dataset, with unparalleled spatial density, for use as a climate proxy. Ancillary Douglas fir and piñon pine tree-ring data collected by the U.S. Forest Service Forest Inventory and Analysis Program (FIA data) were subjected to a series of tests to determine their feasibility as climate proxies. First, temporal coherence between the FIA data and previousl...
متن کاملInvestigating Forest Inventory and Analysis-Collected Tree-Ring Data from Utah as a Proxy for Historical Climate
—Increment cores collected as part of the periodic inventory in the Intermountain West were examined for their potential to represent growth and be a proxy for climate (precipitation) over a large region (Utah). Standardized and crossdated time-series created from pinyon pine (n=249) and Douglas-fir (n=274) increment cores displayed spatiotemporal patterns in growth differences both between spe...
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...
متن کاملA Model-Based Approach to Climate Reconstruction Using Tree-Ring Data
Quantifying long-term historical climate is fundamental to understanding recent climate change. Most instrumentally recorded climate data are only available for the past 200 years, so proxy observations from natural archives are often considered. We describe a model-based approach to reconstructing climate defined in terms of raw tree-ring measurement data that simultaneously accounts for noncl...
متن کاملExtracting coherent tree-ring climatic signals across spatial scales from extensive forest inventory data
Increasing access to extensively replicated and broadly distributed tree-ring collections has led to a greater use of these large data sets to investigate climate forcing on tree growth. However, the number of chronologies added to large accessible databases is declining and few are updated, while chronologies are often sparsely distributed and are more representative of marginal growing enviro...
