Abstract:
The multi-scale synthesis and intercomparison project (MsTMIP) has an overall goal of providing feedback to the terrestrial biospheric modeling (TBM) community to improve the diagnosis and attribution of carbon fluxes at regional and global scales. This project builds upon current and past synthesis activities by developing an integrative framework that all TBMs can use as a tool to continually evaluate overall model performance against a consistent set of observational constraints. There are five main steps of this study: (1) recruit and develop a modeling cohort for participation in this study; (2) assemble high quality driver data sets to be used by participating modeling teams to ensure consistent and comparable model results; (3) develop a detailed model simulation protocol; (4) evaluate model performance against observations, inversions, and other model estimates through a set of quantitative performance measures and metrics based on inventory and flux tower-based observations; and (5) develop an infrastructure to support the model simulations, model comparison, and evaluation. By prescribing standard spin-up procedures, input data sets, and output parameter formats, the proposed intercomparison will quantify and diagnose any biases and uncertainties in TBM estimates of regional and global carbon budgets resulting from differences in model formulation and parameterization. This project is just beginning and we would like to involve a set of terrestrial models that represent the breadth of biospheric modeling activities in the community.
