Land-atmosphere (L-A) interactions are a key component of the global climate system. Water, energy, and carbon transfer between the land surface and planetary boundary layer (PBL) have important impacts on weather and climate variability, predictability, and extremes such as drought. This session focuses on land-atmosphere interactions and characterization of water, energy, and carbon cycle fluxes, and subsequent feedbacks and coupling between the surface and PBL. In particular, the impacts of soil moisture and evapotranspiration on PBL, cloud, and precipitation development remain a challenge to quantify across a range of scales. We invite observation, satellite, and model-based studies of land-atmosphere interactions, particularly at the process-level, and their applications in weather and climate modeling and predictability.  In particular, we emphasize studies that utilize satellite observations and remote sensing for L-A studies.
