  • Usability of Seasonal Climate Forecasts in the Guatemalan Dry Corridor

    Open AccessTalia G Anderson, Talia Anderson et al.ARTICLEWeather, Climate, and Society2026

    Climate services, including seasonal climate forecasts, have been promoted to foster proactive risk management and adaptation to climate variability and change across multiple sectors of society. In smallholder farming and rain-fed systems, where climate variability has an important influence on crop production and food security, information from seasonal climate forecasts has the potential to support and enhance agricultural decision-making. Her…

  • Evaluation of daily gridded climate products using in situ FLUXNET data and tree growth modeling

    Open AccessFeng Wang, Erika K Wise et al.ARTICLEEnvironmental Research Letters2026

    Gridded climate data products have facilitated research in climate and ecology by providing meteorological data continuously across large spatial scales. However, the sensitivity of scientific outcomes to dataset choice remains poorly understood, and evaluation using station-based records can favor datasets built heavily on weather stations. Here, we evaluate seven high-resolution daily gridded datasets covering the contiguous United States using…

    David Frank, David C Frank et al.ARTICLETree-Ring Research2024

    The event "Dendroclimatology Conference: Past, Present, and Future" was hosted on the campus of the University of Arizona in Tucson by the Laboratory of Tree-Ring Research on May 3-5, 2023.Its conception originated from the confluence of four faculty retirements and the fields of dendrochronology in which the retirees specialized.DR. MALCOLM K. HUGHES has contributed to building large-scale networks of "proxy" climate records.He works to establis…

  • Dendroclimatology of Yellow-Cedar (Callitropsis nootkatensis) and Temperature Variability on the Western Slopes of the North Cascades in Washington State, USA, from 1333 to 2015 CE

    Christopher A Trinies, Andrew G Bunn et al.ARTICLETree-Ring Research2022

    Long-term paleoclimate reconstructions of temperature provide context for the magnitude of recent anthropogenic warming, help quantify the climate response to radiative forcing, and better characterize the range of natural variability. In North America, temperature-sensitive tree-ring proxy data remain sparse, which limits the spatial and temporal extent of these reconstructions. Here we present an analysis of yellow-cedar (Callitropsis nootkaten…

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

    Open AccessBecky Brice, Bethany Coulthard et al.ARTICLEEnvironmental Research Letters2021

    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. In part due to short instrumental runoff records, the long-term stationarity of hydroclimatic extremes in this major North American watershed remains poorly understood, highlighting the need to use high-resoluti…

  • Snowpack signals in North American tree rings

    Open AccessBethany Coulthard, Bethany L Coulthard et al.ARTICLEEnvironmental Research Letters2020

    Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn have intensified hydrological droughts in western North America. Climate model projections suggest that continued and severe snowpack reductions are expected over the 21st century, with profound consequences for ecosystems and human welfare. Yet the current understanding of trends and variability in mountain snowpack is limited by the relative…

  • A narrow window of summer temperatures associated with shrub growth in Arctic Alaska

    Open AccessLaia Andreu‐Hayles, Benjamin V Gaglioti et al.ARTICLEEnvironmental Research Letters2020

    Warming in recent decades has triggered shrub expansion in Arctic and alpine tundra, which is transforming these temperature-limited ecosystems and altering carbon and nutrient cycles, fire regimes, permafrost stability, land-surface climate-feedbacks, and wildlife habitat. Where and when Arctic shrub expansion happens in the future will depend in part on how different shrub communities respond to warming air temperatures. Here, we analyze a shru…

  • The potential to strengthen temperature reconstructions in ecoregions with limited tree line using a multispecies approach

    Open AccessM Ross Alexander, Jessie K Pearl et al.ARTICLEQuaternary Research2019

    Tree-ring reconstructions of temperature often target trees at altitudinal or latitudinal tree line where annual growth is broadly expected to be limited by and respond to temperature variability. Based on this principal, regions with sparse tree line would seem to be restricted in their potential to reconstruct past temperatures. In the northeastern United States, there are only two published temperature reconstructions. Previous work in the reg…

  • Multiscale trends and precipitation extremes in the Central American Midsummer Drought

    Open AccessTalia G Anderson, Kevin J Anchukaitis et al.ARTICLEEnvironmental Research Letters2019

    Anecdotal evidence suggests that the timing and intensity of the Central American Midsummer Drought (MSD) may be changing, while observations from limited meteorological station data and paleoclimate reconstructions show neither significant nor consistent trends in seasonal rainfall. Climate model simulations project robust future drying across the region, but internal variability is expected to dominate until the end of the century. Here we use …

  • Improved dendroclimatic calibration using blue intensity in the southern Yukon

    Open AccessRob Wilson, Kevin J Anchukaitis et al.ARTICLEThe Holocene2019Citada por: 1Referencias: 5

    In north-western North America, the so-called divergence problem (DP) is expressed in tree ring width (RW) as an unstable temperature signal in recent decades. Maximum latewood density (MXD), from the same region, shows minimal evidence of DP. While MXD is a superior proxy for summer temperatures, there are very few long MXD records from North America. Latewood blue intensity (LWB) measures similar wood properties as MXD, expresses a similar clim…

  • Tree growth and vegetation activity at the ecosystem-scale in the eastern Mediterranean

    Open AccessBethany Coulthard, Bethany L Coulthard et al.ARTICLEEnvironmental Research Letters2017

    Linking annual tree growth with remotely-sensed terrestrial vegetation indices provides a basis for using tree rings as proxies for ecosystem primary productivity over large spatial and long temporal scales. In contrast with most previous tree ring/remote sensing studies that have focused on temperature-limited boreal and taiga environments, here we compare the normalized difference vegetation index (NDVI) with a network of Pinus brutia tree ring…

  • Reconstructing Northeastern United States temperatures using Atlantic white cedar tree rings

    Open AccessJessie K Pearl, Kevin J Anchukaitis et al.ARTICLEEnvironmental Research Letters2017

    Our knowledge of climate variability in the densely populated Northeastern United States is limited to instrumental data of the last century. Most regional paleoclimate proxies reflect a mix of climate responses, which makes reconstructing historical climate a challenge. Here we analyze tree-ring chronologies from Atlantic white cedar (Chamaecyparis thyoides) as a potential regional paleotemperature proxy. We evaluate our tree-ring network for sp…

  • Climate controls on tree growth in the Western Mediterranean

    Open AccessRamzi Touchan, Kevin J Anchukaitis et al.ARTICLEThe Holocene2017Referencias: 4

    The first large-scale network of tree-ring chronologies from the western Mediterranean (WM; 32°N–43°N, 10°W–17°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation and rotated empirical orthogonal function analyses are applied to 85 tree-ring series and corresponding gridded climate data to assess the climate signal embedded in the network. Chronologies range in length from 80 to 1129 …

  • On the Production of Climate Information in the High Mountain Forests of Guatemala

    Diego Pons, Matthew J Taylor et al.ARTICLEAnnals of the American…2017Referencias: 44

    Guatemala's population is dependent on cash crops and subsistence agriculture, the yield of which depends on both the timing and quantity of rainfall. Detailed knowledge about Guatemala's past, current, and future climate is therefore critical to the well-being of a country so reliant on agriculture. Relatively little information about Guatemala's climate exists, though, due to sparse instrumental records and limited high-resolution paleoclimate …

  • Multi-scale drought and ocean–atmosphere variability in monsoon Asia

    Open AccessManuel Hernández, Caroline C Ummenhofer et al.ARTICLEEnvironmental Research Letters2015

    Spatially extensive and persistent drought episodes have repeatedly influenced human history, including the 'Strange Parallels' drought event in monsoon Asia during the mid-18th century. Here we explore the dynamics of sustained monsoon failure using observed and tree-ring reconstructed drought patterns and a 1300-year pre-industrial community earth system model control run. Both modern observational and climate model drought patterns during year…

  • Dendrochronological Dating of the World Trade Center Ship, Lower Manhattan, New York City

    Dario Martin-Benito, Darío Martin‐Benito et al.ARTICLETree-Ring Research2014

    On July 2010, archaeologists monitoring excavation at the World Trade Center site (WTC) in Lower Manhattan found the remains of a portion of a ship's hull. Because the date of construction and origin of the timbers were unknown, samples from different parts of the ship were taken for dendrochronological dating and provenancing. After developing a 280-year long floating chronology from 19 samples of the white oak group (Quercus section Leucobalanu…

  • How unusual is the 2012–2014 California drought?

    Open AccessDaniel Griffin, Kevin J AnchukaitisARTICLEGeophysical Research Letters2014

    For the past three years (2012–2014), California has experienced the most severe drought conditions in its last century. But how unusual is this event? Here we use two paleoclimate reconstructions of drought and precipitation for Central and Southern California to place this current event in the context of the last millennium. We demonstrate that while 3 year periods of persistent below‐average soil moisture are not uncommon, the current event is…

  • Spatial patterns of eastern Mediterranean climate influence on tree growth

    Open AccessRamzi Touchan, Kevin J Anchukaitis et al.ARTICLEThe Holocene2014Citada por: 3

    The first large-scale network of 79 tree-ring chronologies in the Eastern Mediterranean and Near East (EMNE; 33°N–42°N, 21°E–43°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation analysis and cluster analysis are applied to tree-ring data and gridded climate data to assess the climate signal embedded in the network in preparation for climate field reconstructions and formal proxy/mod…

  • Dendroclimatology in the Eastern Mediterranean

    Open AccessRamzi Touchan, David M Meko et al.ARTICLERadiocarbon2014Referencias: 30

    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. A gradually expanding tree-ring network developed by the first author over the past 15 years has been the framework for some of the most important recent…

  • A long-term perspective on a modern drought in the American Southeast

    Open AccessNeil Pederson, Andrew Reid Bell et al.ARTICLEEnvironmental Research Letters2012

    The depth of the 2006-9 drought in the humid, southeastern US left several metropolitan areas with only a 60-120 day water supply. To put the region's recent drought variability in a long-term perspective, a dense and diverse tree-ring network—including the first records throughout the Apalachicola-Chattahoochee-Flint river basin—is used to reconstruct drought from 1665 to 2010 CE. The network accounts for up to 58.1% of the annual variance in wa…

  • Annual chronology and climate response in Abies guatemalensis Rehder (Pinaceae) in Central America

    Open AccessKevin J Anchukaitis, Matthew J Taylor et al.ARTICLEThe Holocene2012Citada por: 1Referencias: 4

    The continued expansion of dendroclimatology into Mesoamerica requires the identification and evaluation of species whose rings can be precisely dated and then statistically compared with precipitation and temperature variability in order to make inferences about past climate. Here, we establish the basis for using Abies guatemalensis Rehder (Pinaceae) for climate reconstruction in Central America. Annual crossdating in this montane species is de…

  • Varying boreal forest response to Arctic environmental change at the Firth River, Alaska

    Open AccessLaia Andreu-Hayles, Laia Andreu‐Hayles et al.ARTICLEEnvironmental Research Letters2011

    In the second paragraph of the section '2.3 Meteorological and remote sensing data', the Normalized Difference Vegetation Index (NDVI) data set used was incorrectly referred to as GIMMS-NDVI version 3G with a 0.084 spatial resolution. This should be corrected to GIMMS-NDVI version G with a 0.07 spatial resolution
