The Spatial Variability Of Actual Evapotranspiration Across The Amazon River Basin Based On Remote Sensing Products Validated With Flux Towers
Paca, V. H., Espinoza-Dávalos, G. E., Hessels, T. M., Moreira, D. M., Comair, G. F., Bastiaanssen, W. G.

Actual evapotranspiration (ET) is a major component of the water balance. While several international flux measurement programs have been executed in the tropical rain forest of the Amazon, those measurements represent the evaporative process at a few selected sites only. The aim of this study is to obtain the spatial distribution …

Data-Based Perfect-Deficit Approach To Understanding Climate Extremes And Forest Carbon Assimilation Capacity
Wei, S., Yi, C., Hendrey, G., Eaton, T., Rustic, G., Wang, S., Liu, H., Krakauer, N. Y., Wang, W., Desai, A. R., Montagnani, L., Tha Paw U, K., Falk, M., Black, A., Bernhofer, C., Grünwald, T., Laurila, T., Cescatti, A., Moors, E., Bracho, R., Valentini, R.

Several lines of evidence suggest that the warming climate plays a vital role in driving certain types of extreme weather. The impact of warming and of extreme weather on forest carbon assimilation capacity is poorly known. Filling this knowledge gap is critical towards understanding …

A., Arneth, A., Aurela, M., Bernhofer, C., Cescatti, A., Dellwik, E., Duce, P., Gianelle, D., van Gorsel, E., Kiely, G., Knohl, A., Margolis, H., McCaughey, H., Merbold, L., Montagnani, L., Papale, D., Reichstein, M., Saunders, M., Serrano-Ortiz, P., Sottocornola, M., Spano, D., Vaccari, F., Varlagin, A.

The energy balance at most surface-atmosphere flux research sites remains unclosed. The mechanisms underlying the discrepancy between measured energy inputs and outputs across the global FLUXNET tower network are still under debate. Recent reviews have identified …

Improving Canopy Processes In The Community Land Model Version 4 (CLM4) Using Global Flux Fields Empirically Inferred From FLUXNET Data
Bonan, G.B., Lawrence, P.J., Oleson, K.W., Levis, S., Jung, M., Reichstein, M., Lawrence, D.M., Swenson, S.C.

The Community Land Model version 4 (CLM4) overestimates gross primary production (GPP) compared with data-driven estimates and other process models. We use global, spatially gridded GPP and latent heat flux …

Separation Of Net Ecosystem Exchange Into Assimilation And Respiration Using A Light Response Curve Approach: Critical Issues And Global Evaluation
Lasslop, G., Reichstein, M., Papale, D., Richardson, A. D., Arneth, A., Barr, A., Stoy, P., Wohlfahrt, G.

The measured net ecosystem exchange (NEE) of CO2 between the ecosystem and the atmosphere reflects the balance between gross CO2 assimilation [gross primary production (GPP)] and ecosystem respiration (Reco). For understanding the mechanistic responses of ecosystem processes to environmental change …

Tropical vegetation is a major source of global land surface evapotranspiration, and can thus play a major role in global hydrological cycles and global atmospheric circulation. Accurate prediction of tropical evapotranspiration is critical to our understanding of these processes under changing climate. We examined the controls on …
