  • Revealing how intra- and inter-annual variability of carbon uptake (GPP) affects wood cell biomass in an eastern white pine forest

    Open AccessPaulina F Puchi, Myroslava Khomik et al.ARTICLEEnvironmental Research Letters2023

    Forests are major terrestrial carbon (C) sinks and play a crucial role in climate change mitigation. Despite extensive studies on forest C sequestration, the relationship between seasonal C uptake and its allocation to woody biomass is poorly understood. Here we used a novel dendro-anatomical approach to investigate the relationships between climate variability, C uptake, and woody biomass growth in an 80 year-old eastern white pine ( Pinus strob…

  • Stomatal response to decreased relative humidity constrains the acceleration of terrestrial evapotranspiration

    Open AccessMingzhong Xiao, Zhongbo Yu et al.ARTICLEEnvironmental Research Letters2020

    Terrestrial evapotranspiration (ET) is thermodynamically expected to increase with increasing atmospheric temperature; however, the actual constraints on the intensification of ET remain uncertain due to a lack of direct observations. Based on the FLUXNET2015 Dataset, we found that relative humidity (RH) is a more important driver of ET than temperature. While actual ET decrease at reduced RH, potential ET increases, consistently with the complem…

  • Quantifying the effect of forest age in annual net forest carbon balance

    Open AccessSimon Besnard, Nuno Carvalhais et al.ARTICLEEnvironmental Research Letters2018

    Forests dominate carbon (C) exchanges between the terrestrial biosphere and the atmosphere on land. In the long term, the net carbon flux between forests and the atmosphere has been significantly impacted by changes in forest cover area and structure due to ecological disturbances and management activities. Current empirical approaches for estimating net ecosystem productivity (NEP) rarely consider forest age as a predictor, which represents vari…

  • Disentangling climatic and anthropogenic controls on global terrestrial evapotranspiration trends

    Open AccessJiafu Mao, Wenting Fu et al.ARTICLEEnvironmental Research Letters2015

    We examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models. A significant increasing trend of ET in each hemisphere was consistently revealed by observationally-constrained data and multi-model ensembles that considered historic natural and anthropogenic drivers. The climate impacts were simulat…

  • Terrestrial Gross Carbon Dioxide Uptake: Global Distribution and Covariation with Climate

    Open AccessChristian Beer, Markus Reichstein et al.ARTICLEScience2010

    Carbon Cycle and Climate Change As climate change accelerates, it is important to know the likely impact of climate change on the carbon cycle (see the Perspective by Reich ). Gross primary production (GPP) is a measure of the amount of CO 2 removed from the atmosphere every year to fuel photosynthesis. Beer et al. (p. 834 , published online 5 July) used a combination of observation and calculation to estimate that the total GPP by terrestrial pl…

  • Climate control of terrestrial carbon exchange across biomes and continents

    Open AccessChuixiang Yi, Daniel Ricciuto et al.ARTICLEEnvironmental Research Letters2010

    Understanding the relationships between climate and carbon exchange by terrestrial ecosystems \nis critical to predict future levels of atmospheric carbon dioxide because of the potential \naccelerating effects of positive climate–carbon cycle feedbacks. However, directly observed \nrelationships between climate and terrestrial CO2 exchange with the atmosphere across biomes \nand continents are lacking. Here we present data describing the relatio…

  • Meteorological influences on the spatial and temporal variability of NO 2 in Toronto and Hamilton

    Open AccessM ALTAF ARAIN, ROSE BLAIR et al.ARTICLECanadian Geographies /…2009References: 42

    The spatial and temporal variability of nitrogen dioxide (NO 2 ) concentrations and their relationships with meteorology was evaluated in the Toronto–Hamilton urban airshed. NO 2 concentrations were highest in the early morning and late evening. Mean concentrations were highest in winter, although individual one‐hour NO 2 concentrations were found to be highest in summer. Wind direction was the strongest control on hourly NO 2 concentration, and …
