AGU sessions organized by BGC membersSession B032: Ecosystem Experiment and Model Synthesis: Uncertainty Reduction in Understanding Terrestrial Biosphere Feedback with Atmospheric and Climatic Change
Feedbacks between terrestrial ecosystems, atmospheric CO2, and climate remain a huge uncertainty in Earth-System modelling. This session will define a roadmap of process level understanding necessary to both improve models and define questions for experiments in order to further our predictive understanding of terrestrial biosphere feedbacks with atmospheric CO2 and climate.

Session GC027: Emerging perspectives on land in a changing world
Earth’s land surface embodies the dynamic interplay of the physical, social and economic processes that constitute global change. This session aims to bring together a diverse group of natural and social scientists to explore emerging perspectives on land.
Co-Convener: Markus Reichstein, MPI-BGC
Session B065: Plant traits and biogeochemical cycles
Plant traits extend the range of earth observations to the level of individual organisms, providing a link to ecosystem function and modeling in the context of rapid global changes. However, overcoming the differences in temporal and spatial scales between plant trait data and biogeochemical cycles remains a challenge. This session will address the role of plant species, biodiversity and adaptation / acclimation in the biogeochemical cycles of water, carbon, nitrogen and phosphorus. We welcome conceptual, observational, experimental and modeling approaches, and studies from the local to the global scale, including e.g remote sensing observations.
Convener: Jens Kattge, MPI-BGC
Session EP019: International Critical Zone Research: Status, Networking and Challenges
Recently, several activities in Europe, China and the US have been initiated to develop and establish an international network of CZOs and to define an overarching research questions for critical zone research. These initiatives are follow ups of the first science CZO conference that took place in Delaware, 2011. Present activities target the national and EU-wide realignment and connection of both existing and proposed structures and programs. The session aims at presenting ongoing critical zone research, the challenges its encounters and the status of international collaboration activities thereby focussing on examples of bi- or multilateral projects within CZ Science. We foster contributions dealing with understanding and predicting critical zone response to land-use and climate change on the catchment scale. Of particular interest are hill slope dynamics based on shallow subsurface structure, caused by geomorphological, hydrological and pedological processes, combined with or steering biogeochemical cycles and weathering within the vadose zone.

Session A030: Constraining Biosphere-Atmosphere Exchange Processes using Remote-sensing and In Situ Networks
This session focuses on modeling frameworks, both top-down and bottom-up approaches, that investigate biosphere-atmosphere exchange processes using atmospheric data from various observational platforms, both in-situ as well as remotely-sensed. We particularly invite contributions on: 1) estimation and/or verification of greenhouse gas (GHG) budgets of biospheric and anthropogenic fluxes; 2) inverse models and data assimilation systems for obtaining GHG budgets, or strategies for coupling atmospheric inversions to biogeochemical models; 3) the use of multiple species (e.g. H2O and CO2, carbon isotopes, OCS and CO2) to provide insight into process-based model formulations; 4) research focusing on the constraint on GHG budgets induced by new data from the Orbiting Carbon Observatory-2 (OCO-2) and the Soil Moisture Active Passive (SMAP) missions.
