Improved understanding of drought controls on seasonal variation in Mediterranean forest canopy CO₂ and water fluxes through combined in situ measurements and ecosystem modelling / Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; García, R. (Laboratoire des Sciences du Climat et de l'Environment) ; Friend, A. D. (University of Cambridge. Department of Geography) ; Zaehle, S. (Laboratoire des Sciences du Climat et de l'Environment) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals)
Water stress is a defining characteristic of Mediterranean ecosystems, and is likely to become more severe in the coming decades. Simulation models are key tools for making predictions, but our current understanding of how soil moisture controls ecosystem functioning is not sufficient to adequately constrain parameterisations.

Soil respiration (SR) constitutes the largest flux of CO₂ from terrestrial ecosystems to the atmosphere. However, there still exist considerable uncertainties as to its actual magnitude, as well as its spatial and interannual variability. [...]

A data assimilation framework for constraining upscaled cropland carbon flux seasonality and biometry with MODIS / Sus, Oliver (Centre de Recerca Ecològica i Aplicacions Forestals) ; Heuer, M. W. (Air Resources Laboratory (U.S.). Atmospheric Turbulence and Diffusion Division) ; Meyers, T. P. (Air Resources Laboratory (U.S.). Atmospheric Turbulence and Diffusion Division) ; Williams, M. (University of Edinburgh. School of GeoSciences)
Agroecosystem models are strongly dependent on information on land management patterns for regional applications. Land management practices play a major role in determining global yield variability, and add an anthropogenic signal to the observed seasonality of atmospheric CO₂ concentrations. [...]

(Centre Tecnològic Forestal de Catalunya) ; Vayreda Duran, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals)
Accurate estimates of C stocks and fluxes of soil organic carbon (SOC) are needed to assess the impact of climate and land use change on soil C uptake and soil C emissions to the atmosphere. Here, we present an assessment of SOC stocks in forests, shrublands and grasslands of peninsular Spain based on field measurements in more than 900 soil profiles. [...]

As a key component of the carbon cycle, soil CO₂ efflux (SCE) is being increasingly studied to improve our mechanistic understanding of this important carbon flux. Predicting ecosystem responses to climate change often depends on extrapolation of current relationships between ecosystem processes and their climatic drivers to conditions not yet experienced by the ecosystem.
