Typically at the scale of multiple meters, mesoscale research platforms provide critical knowledge in geosciences and environmental studies by integrating key mechanisms at smaller scales with observations of coupled processes at field scales that are multi-physics with multiscale heterogeneities. The complexity and heterogeneities of the physical, chemical and biological interactions observable at mesoscales are relevant to the field scales, yet this intermediate scale is small enough to allow intense control, observations and manipulation, which allows the decoupling of the multi-scale and complex problems.

This session invites contributions on mesoscale platforms for Earth and environmental research. Those focused on the heat and mass transfers through the interfaces and interactions between hydrology, ecology, biogeochemistry and reactive transport are specifically welcomed. We encourage cross-cutting discussions on specific challenges facing mesoscale research and the opportunities it presents in advancing Earth and environmental science across multiple scales for technological developments and predictive numerical modeling.
