Session Proposal: Advances in Modeling of Terrestrial Ecosystem Carbon and Water Fluxes (AGU25)

B004
Advances in Modeling of Terrestrial Ecosystem Carbon and Water Fluxes

Session ID#: 250678

Session Description:
Carbon and water fluxes of terrestrial ecosystems are strongly coupled. Ground-based and satellite-based observations have been used to characterize, monitor, and model terrestrial ecosystems' composition, structure, and function. This session welcomes contributions that (1) develop or improve the process-based models (e.g., dynamic global vegetation models), satellite-based models, multi-variate statistical models and AI/ML models) that estimate hourly or daily gross and net primary production (GPP and NPP) and ecosystem respiration (ER), as well as evapotranspiration (ET) or transpiration (T) and evaporation (E), and compare various carbon and water flux data products from site to regional and global scales; (2) quantify interannual variability and decadal trends of carbon and water fluxes and identify their driving factors; (3) assess and attribute the contributions of terrestrial carbon fluxes to the atmospheric CO2 concentration dynamics; and (4) evaluate and attribute the contribution of terrestrial water fluxes to the water budget and atmospheric water dynamics.
