H44C:
Advances in Understanding Land-Atmosphere Interactions in a Changing Environment IV

Submit an Abstract to this Session



Session ID#: 34348

Session Description:
Land-atmosphere interactions are a key component of the Earth system. Atmospheric impacts on land as well as land cover perturbations alter land-atmosphere water and energy fluxes. Such changes have important impacts on weather and climate variability, and hydrometeorological extremes such as heatwaves and drought. However, traditional measurements only provide an incomplete picture of such relationships, resulting in poorly understood linkages of water and energy cycle components, thus limiting current modeling applications. This session invites presentations that address the physical processes (from bedrock to boundary layer) through which land-atmosphere coupling occurs in nature, how large scale field experiments and remote sensing can improve understanding of such processes, how processes are represented in numerical models, and how land-atmosphere interactions contribute to our understanding and prediction capabilities of terrestrial climate and water cycle over a range of spatial and temporal scales.
