Surface-Atmosphere Interactions: Advances in Spatial and Temporal Scaling of Surface-Atmosphere Fluxes
Session ID#: 80245
Session Description:
Land surface heterogeneity influences patterns of energy, water, and greenhouse gas exchanges and their atmospheric response. The resulting spatial variability is described using direct and remotely sensed measurements from various platforms, alongside numerical simulations. However, these are often performed at differing spatial and temporal scales, none of which perfectly matches the scales of the environmental processes being studied.
For example, the small scale of tower eddy covariance flux measurements limits their spatial representativeness and may neglect larger-scale transport processes. Conversely, ecosystem and atmospheric models operate at larger scales and struggle to incorporate sub-grid processes.
This session focuses on linking flux observations to gridded models. We welcome advances in upscaling surface flux measurements, downscaling atmospheric inversions, and diagnosing their scale-dependence on surface and atmospheric processes. Of particular interest are studies exploring how surface heterogeneity drives local atmospheric circulations, and how those circulations influence the reliability and representativeness of surface flux measurements.
