Physical and biological land surface characteristics affect how energy, water, aerosols, and greenhouse gases are exchanged with the atmosphere. Thus, interactions between the land surface and the atmosphere represent a key component of the climate system. To improve predictions of global and regional climates, a better understanding of the tight coupling between land and atmosphere is needed. Observational and experimental studies can improve our understanding of land-atmosphere interactions. For example, eddy covariance measurements of fluxes of energy and matter help constrain flux dynamics across multiple time scales from hours to years and create large, long-term datasets to examine variability in land-atmosphere interactions. This data provides base data for ecosystem models. Chamber studies have provided the information needed to investigate process-based dynamics of GHG emissions. New technologies are expanding measurements to all landscapes across Canada – i.e., agricultural, forest, and peatland sites. These studies provide powerful tools to explore biophysical and biogeochemical processes underlying land-atmosphere interactions. This session highlights innovative research of all aspects of field campaigns observing land-atmosphere interactions.
