  • Climate constrains the enhancement of CO 2 fertilization on forest gross primary productivity

    Open AccessXinyuan Wei, Daniel J Hayes et al.ARTICLEEnvironmental Research Letters2025

    Forest gross primary production (GPP) is influenced by the interplay between climate conditions and atmospheric CO 2 levels, which interact in complex ways, generating both compensating and amplifying effects. In this study, eddy covariance flux measurements from 50 forest ecosystems were integrated with simulations from 14 terrestrial biosphere models to investigate how climate conditions and atmospheric CO 2 concentrations regulate forest GPP. …

  • Five years of variability in the global carbon cycle

    Open AccessZichong Chen, D N Huntzinger et al.ARTICLEEnvironmental Research Letters2021

    Year-to-year variability in CO 2 fluxes can yield insight into climate-carbon cycle relationships, a fundamental yet uncertain aspect of the terrestrial carbon cycle. In this study, we use global observations from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite for years 2015–2019 and a geostatistical inverse model to evaluate 5 years of interannual variability (IAV) in CO 2 fluxes and its relationships with environmental drivers. OCO-2 la…

  • Climate-driven risks to the climate mitigation potential of forests

    Open AccessWilliam R L Anderegg, Anna T Trugman et al.ARTICLEScience2020

    Risks to mitigation potential of forests Much recent attention has focused on the potential of trees and forests to mitigate ongoing climate change by acting as sinks for carbon. Anderegg et al. review the growing evidence that forests' climate mitigation potential is increasingly at risk from a range of adversities that limit forest growth and health. These include physical factors such as drought and fire and biotic factors, including the depre…

  • Evaluation of simulated soil carbon dynamics in Arctic-Boreal ecosystems

    Open AccessD N Huntzinger, Kevin Schaefer et al.ARTICLEEnvironmental Research Letters2020

    Given the magnitude of soil carbon stocks in northern ecosystems, and the vulnerability of these stocks to climate warming, land surface models must accurately represent soil carbon dynamics in these regions. We evaluate soil carbon stocks and turnover rates, and the relationship between soil carbon loss with soil temperature and moisture, from an ensemble of eleven global land surface models. We focus on the region of NASA’s Arctic-Boreal vulner…

  • The Arctic-Boreal vulnerability experiment model benchmarking system

    Open AccessEric Stofferahn, Joshua B Fisher et al.ARTICLEEnvironmental Research Letters2019

    NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE) integrates field and airborne data into modeling and synthesis activities for understanding Arctic and Boreal ecosystem dynamics. The ABoVE Benchmarking System (ABS) is an operational software package to evaluate terrestrial biosphere models against key indicators of Arctic and Boreal ecosystem dynamics, i.e.: carbon biogeochemistry, vegetation, permafrost, hydrology, and disturbance. The ABS …

  • Forests dominate the interannual variability of the North American carbon sink

    Open AccessYoichi P Shiga, A M Michalak et al.ARTICLEEnvironmental Research Letters2018

    Understanding what drives the interannual variability (IAV) of the land carbon sink is crucial for improving future predictions of this important, yet uncertain, component of the climate system. While drivers of global and hemispheric-scale net ecosystem exchange (NEE) IAV have been investigated, our understanding of the drivers of NEE IAV at regional scales (e.g. sub-continental, biome-level) is quite poor. Here we explore the biome-level attrib…

  • Missing pieces to modeling the Arctic-Boreal puzzle

    Open AccessJoshua B Fisher, Daniel J Hayes et al.ARTICLEEnvironmental Research Letters2017

    NASA has launched the decade-long Arctic-Boreal Vulnerability Experiment (ABoVE). While the initial phases focus on field and airborne data collection, early integration with modeling activities is important to benefit future modeling syntheses. We compiled feedback from ecosystem modeling teams on key data needs, which encompass carbon biogeochemistry, vegetation, permafrost, hydrology, and disturbance dynamics. A suite of variables was identifi…

  • Global land carbon sink response to temperature and precipitation varies with Enso phase

    Open AccessYuanyuan Fang, A M Michalak et al.ARTICLEEnvironmental Research Letters2017

    Climate variability associated with the El Niño-Southern Oscillation (ENSO) and its consequent impacts on land carbon sink interannual variability have been used as a basis for investigating carbon cycle responses to climate variability more broadly, and to inform the sensitivity of the tropical carbon budget to climate change. Past studies have presented opposing views about whether temperature or precipitation is the primary factor driving the …

  • 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…
