Warm spring reduced carbon cycle impact of the 2012 US summer drought

Creator:: Wolf, Sebastian, Keenan, Trevor F., Fisher, Joshua B., Baldocchi, Dennis D., Desai, Ankur R., Richardson, Andrew D., Scott, Russell L., Law, Beverly E., Litvak, Marcy E., Brunsell, Nathaniel A., Peters, Wouter, and van der Laan-Luijkx, Ingrid T.
Abstract:: The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting...

Thermal optimality of net ecosystem exchange of carbon dioxide and underlying mechanisms

Abstract:: It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...

On the temporal upscaling of evapotranspiration from instantaneous remote sensing measurements to 8-day mean daily-sums

Creator:: Ryu, Youngryel, Baldocchi, Dennis D., Black, T. Andrew, Detto, Matteo, Law, Beverly E., Leuning, Ray, Miyata, Akira, Reichstein, Markus, Vargas, Rodrigo, Ammann, Christof, Beringer, Jason, Flanagan, Lawrence B., Gu, Lianhong, Hutley, Lindsay B., Kim, Joon, McCaughey, Harry, Moors, Eddy J., Rambal, Serge, and Vesala, Timo
Abstract:: The regular monitoring of evapotranspiration from satellites has been limited because of discontinuous temporal coverage, resulting in snapshots at a particular point in space and time. We developed a temporal upscaling scheme using satellite-derived instantaneous estimates of evapotranspiration to produce a daily-sum evapotranspiration averaged over an 8-day interval. We tested...

Performance of Linear and Nonlinear Two-Leaf Light Use Efficiency Models at Different Temporal Scales

Creator:: Wu, Xiaocui, Ju, Weimin, Zhou, Yanlian, He, Mingzhu, Law, Beverly E., Black, T. Andrew, Margolis, Hank A., Cescatti, Alessandro, Gu, Lianhong, Montagnani, Leonardo, Noormets, Asko, Griffis, Timothy J., Pilegaard, Kim, Varlagin, Andrej, Valentini, Riccardo, Blanken, Peter D., Wang, Shaoqiang, Wang, Huimin, Han, Shijie, Yan, Junhua, Li, Yingnian, Zhou, Bingbing, and Liu, Yibo
Abstract:: The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a...

Memory effects of climate and vegetation affecting net ecosystem CO2 fluxes in global forests

Creator:: Besnard, Simon, Carvalhais, Nuno, Arain, M. Altaf, Black, Andrew, Brede, Benjamin, Buchmann, Nina, Chen, Jiquan, Clevers, Jan G. P. W., Dutrieux, Loic P., Gans, Fabian, Herold, Martin, Jung, Martin, Kosugi, Yoshiko, Knohl, Alexander, Law, Beverly E., Paul-Limoges, Eugenie, Lohila, Annalea, Merbold, Lutz, Roupsard, Olivier, Valentini, Riccardo, Wolf, Sebastian, Zhang, Xudong, and Reichstein, Markus
Abstract:: Forests play a crucial role in the global carbon (C) cycle by storing and sequestering a substantial amount of C in the terrestrial biosphere. Due to temporal dynamics in climate and vegetation activity, there are significant regional variations in carbon dioxide (CO2) fluxes between the biosphere and atmosphere in forests...
