Snowpack signals in North American tree rings

Environmental Research Letters, 2021
Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn have intensified hydrological droughts in western North America.

Paleohydrological context for recent floods and droughts in the Fraser River Basin, British Columbia, Canada

Environmental Research Letters, 2021
The recent intensification of floods and droughts in the Fraser River Basin (FRB) of British Columbia has had profound cultural, ecological, and economic impacts that are expected to be exacerbated further by anthropogenic climate change.

The Historical Development of Large‐Scale Paleoclimate Field Reconstructions Over the Common Era

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract Climate field reconstructions (CFRs) combine modern observational data with paleoclimatic proxies to estimate climate variables over spatiotemporal grids during time periods when widespread observations of climatic conditions do not exist. The Common Era (CE) has been a period over which many seasonally‐ and annually‐resolved CFRs have been ...

Dendroecology of Macrolobium acaciifolium (Fabaceae) in Central Amazonian floodplain forests [PDF]

Acta Amazonica, 2018
The forest dynamics in the Amazonian floodplains is strongly triggered by the flood pulse. Trees respond to unfavorable growth conditions during the flood period by cambial dormancy, which results in the formation of annual growth rings.

Dendrochronological Potential of Drought-Sensitive Tree Stands in Armenia for the Hydroclimate Reconstruction of the Lesser Caucasus

Atmosphere, 2021
Existing high-resolution reconstructions of hydroclimate variability in the Caucasus are lacking tree-ring data from Armenian Plateau, the most continental part of the region.

SNOTEL, the Soil Climate Analysis Network, and water supply forecasting at the Natural Resources Conservation Service: Past, present, and future

JAWRA Journal of the American Water Resources Association, Volume 59, Issue 4, Page 585-599, August 2023., 2023
Abstract The Snow Survey and Water Supply Forecasting (SSWSF) Program and the Soil Climate Analysis Network (SCAN) of the United States Department of Agriculture's Natural Resources Conservation Service (NRCS) generate key observational and predictive information for water managers.

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

Geosciences, 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 ...

Dendroclimatology in the Eastern Mediterranean [PDF]

Radiocarbon, 2014
Dendroclimatology in the Eastern Mediterranean (EM) region has made important contributions to the understanding of climate variability on timescales of decades to centuries. These contributions, beginning in the mid-20th century, have value for resource management, archaeology, and climatology.

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

Journal 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
