Biosphere under changing clouds, aerosols, and solar radiation modification
Convener: TC ChakrabortyECSECS | Co-conveners: Yuan Zhang, Mike O'SullivanECSECS, chandan sarangi, Long Cao
Changes in cloud cover and emissions of natural and anthropogenic aerosols can significantly impact the biosphere through modifying climate (i.e., temperature, precipitation, quantity and quality of surface solar radiation), ozone production, nutrient deposition, etc. Meanwhile, the altered biosphere can further regulate the climate system by affecting mass and energy exchanges between the Earth's surface and the atmosphere through biophysical (altering surface albedo, evapotranspiration, etc.) and biochemical (changing carbon budget) processes. Clouds, aerosols, and interactions with the biosphere remain large sources of uncertainty in our understanding of the drivers of climate change. Thus, accurately describing these processes and feedbacks will help reduce uncertainties in climate projections, inform local to regional air quality control policies and better constrain the impacts of solar radiation modification strategies.

This session aims to bring together researchers working on the interaction between the biosphere, clouds and aerosols. We welcome contributions from scientists investigating the mechanisms and quantifying the impacts of cloud- or aerosol-induced changes on the biosphere, as well as their feedback to the climate system. We also welcome studies on solar radiation modification, especially those focusing on the biosphere. Studies across scales (local to global), over land or ocean and using various techniques (observational, experimental and modelling) are welcome.
