Our understanding of water, energy, and greenhouse gas cycling within the earth system is grounded in in-situ observations. Globally, hundreds of eddy covariance flux sites and mobile ground/airborne platforms measure exchanges of water, energy, and trace gases between ecosystems and the atmosphere.

Many flux sites contribute to regional networks and the global FLUXNET, which provides globally synthesized and comprehensive datasets. Such joint efforts serve as the foundation for studying biosphere-atmosphere interactions from local to global and from diel to decadal scales.

This session focuses on the current state and future perspectives of flux measurements, and their use in syntheses and modeling. We welcome contributions that improve our understanding through theories, instrumentation, models, datasets, and applications, especially work integrating different data types, GHGs, regions or scales. We also encourage developments and results within the context of research grand-themes (e.g., AmeriFlux year of water fluxes and EU drought synthesis).
