Advances in Understanding Land–Atmosphere Interactions in a Changing Environment I


Submit an Abstract to this Session


Session ID#: 62331

Session Description:
Land-atmosphere interactions are a key component of the Earth System. Spatial and temporal variations in surface characteristics (e.g., soil moisture, vegetation) and attendant land-atmosphere fluxes (e.g., evapotranspiration) can feed back on local climate, including hydrometeorological extremes such as heatwaves and drought. Observing, and hence, modeling of coupled land-atmospheric processes is a major challenge due to the complexity of the processes involved and scale heterogeneity of the land surface. This session invites studies employing novel observational or modeling frameworks to elucidate time and space variations in the strength of coupled land-atmosphere processes and feedbacks (from bedrock to boundary layer). Studies integrating meso-scale networks (e.g., OKMESONET, ARM-SGP, and AmeriFlux), field campaign data (e.g., PECAN, LAFE, HI-SCALE), or satellite data are of particular interest. Also, studies addressing the quantifiable role of land-atmosphere processes in weather predictability and climate variability and change, for example in the context of the CMIP6 participating models, are welcomed.
