B004:
Advances in uncertainty assessment and reduction for terrestrial carbon cycle diagnosis and prediction





Session ID#: 24868

Session Description:
Quantifying and reducing uncertainty in diagnosed and modeled carbon fluxes and stocks is a major challenge for the carbon cycle science community. Uncertainty in regional- to global-scale diagnoses limits our ability to test and develop accurate prognostic carbon cycle models, a major source of uncertainty in projections of future climate. However, recent advances in observations, ecosystem experiments, data assimilation techniques, and scientific computing have improved diagnostic and prognostic skill in carbon cycle science. We invite submissions that (1) investigate uncertainty in model forcings, parameters, or structure and the resulting uncertainty in diagnosis and/or predictions; (2) quantify and reduce uncertainty using benchmarking datasets and model-data integration; and (3) document new process understanding, observations, experiments or datasets that will advance this field. We welcome innovative work from all means of studying the terrestrial carbon cycle, including inventory assessments, ecosystem and earth system models, field experiments, remote sensing, and model-data syntheses.
