We describe the implementation of the Vaganov-Shashkin tree-ring growth model (VSM) in MATLAB. VSM, originally written in Fortran, mimics subdaily and daily resolution processes of cambial growth as a function of soil moisture, air temperature, and insolation, with environmental forcing modeled as...

The current state of dendrochronology's contributions to climatology is surveyed, with an emphasis on the extent to which its actual and potential strengths are being used, and its weaknesses recognized and surmounted. After the growth in climatologists' interest in the potential of ...

We explore a probabilistic, hierarchical Bayesian approach to the simultaneous reconstruction of local temperature and soil moisture from tree-ring width observations. The model explicitly allows for differing calibration and reconstruction interval responses of the ring-width series to climate due ...

The first dendroclimatic reconstruction of May 1 snow water equivalent (SWE) was developed from a Sequoiadendron giganteum regional tree-ring chronology network of 23 sites in central California for the period 90-2012 CE. The reconstruction is based on a significant relationship between May 1 SWE...

We report new data on tree-ring growth in northern European Russia, a region with a hitherto relatively sparse tree-ring network. We explore its associations with climate variability. Areas, sampling locations and trees were selected for representativeness rather than climate sensitivity. Using...

The AD 536 volcanic eruption caused a drastic decrease in tree-ring widths, cell wall thickness, carbon and oxygen isotopic values in larch tree cellulose, and frost-ring formation, effects which are without an analogue over the past 2000 years in Siberia.

This paper briefly discusses climate history in the Sierra Nevada, California, USA, in relation to the ecosystem dynamics in the area.

We examine the relationships, over the past millennium, between tree-ring chronologies from long-lived pines at their upper and lower limits in four mountain ranges in and near to the semi-arid Great Basin. We confirm LaMarche's (1974a) finding, based on a single mountain range in this same region, ...

Chinese pine (Pinus tabulaeformis) trees from the Helan Mountain range in central China have been used to reconstruct total January-July precipitation from AD 1775 to 1998. The Helan Mountain range is located between the eastern Ningxia plain and the western A Lashan plateau. For the calibration...

In this letter to the editor, certain issues on a recent report by Esper et al. [Supplementary material available on Science Online at www.sciencemag.org/cgi/content/full/295/5563/2250/DC1] on the use of low-frequency signals in long tree-ring chronologies for reconstructing past temperature...
