| A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectiveness of policies aiming to reduce greenhouse gas emissions and increase carbon sequestration. Building an integrated carbon observation system requires transformational advances from the existing sparse, exploratory framework towards a dense, robust, and sustained system in all components: anthropogenic emissions, the atmosphere, the ocean, and the terrestrial biosphere. The paper is addressed to scientists, policymakers, and funding agencies who need to have a global picture of the current state of the (diverse) carbon observations. We... |

| We present an overview of water transport in plants, exploring how the theory has formed the basis of models of water use, carbon assimilation and plant growth. We outline the cohesion theory of water transport, and explore the vulnerabilities of the transport system to cavitation. The relationships between water relations and CO2 gain are outlined using a detailed model of the soil–plant–atmosphere continuum, coupling vapour-phase losses of water to liquid-phase supply to the leaf. Measurements of whole ecosystem exchange of latent energy and CO2 via eddy covariance are increasingly common. These measurements are generated almost continuously, and so provide time series of land-surface process dynamics that have proved very useful for testing models. We... |
