To understand and appropriately describe the biosphere-atmosphere exchanges of water, energy, carbon and other elements is fundamental in diagnosing and forecasting future Earth system states and dynamics. The uncertainties underlying processes are still very significant, as is demonstrated e.g. by the poor ability of Earth system models to describe terrestrial ecosystem dynamics at multiple temporal and spatial scales. Confronting terrestrial biogeochemical models with an ever-increasing amount and diversity of observational data streams is an essential step in improving our understanding and representation ability of terrestrial biogeochemical dynamics.
With this session we aim at bringing together contributions that focus on integrating models and multiple sources of observations, ranging from in-situ to satellite measurements, to advance our understanding of terrestrial ecosystem functioning from the local to the global scale. We especially encourage studies that address the topic through inversion frameworks, such as a model-data-fusion or data-assimilation approaches. But we also welcome other studies that confront terrestrial biogeochemical models with data that can range from pure observational to manipulative experiments; and that explore the links between ecosystem states and responses to environmental forcing, including inter annual variability or responses to extreme climate events.
