The American Geophysical Union (AGU) is accepting abstracts for the AGU Fall Meeting 2022. This hybrid meeting will take place 12-16 December 2022 in Chicago, Illinois and online.
The following sessions are accepting abstracts:
SESSION AE003: Lightning, Air Quality, and Climate
Conveners: Yang Li, Michael Stock, and Daile Zhang
Lightning plays an important role in reshaping air quality and also serves as an essential climate variable. For example, lightning itself is a producer of NOx and could start forest fires, directly influencing the air quality in its vicinity. Conversely, enhanced air pollutants such as climate forcers and aerosols from fires or anthropogenic sources could perturb Earth's energy balance, and have been linked to increased convective activity thus enhancing lightning under a changing climate. Interpreting the intricate relationships in-between lightning, air quality, and climate is critical to addressing air pollution concerns and mitigating climate change. The goal of this session is to solicit recent measurements and/or computational modeling studies that advance our understanding of the impacts of lightning on air quality and climate, as well as the feedback of changes in air pollutants and meteorological factors on convective activity and lightning density across local- to global- scales and in the short- to long- terms.

SESSION A021: Atmospheric Chemistry in the Wildfire Plume
Conveners: Yang Li, Rebecca R. Buchholz, and Rebecca Schwantes
Wildfires emit large quantities of trace gases and aerosols, which influence atmospheric composition as well as the chemical and physical processes that reshape air quality and the climate system. For example, the photochemically reactive compounds in wildfire smoke plumes can enhance tropospheric ozone to have significant impacts on air quality at local and downwind locations. Wildfire-generated aerosol particles can also impact radiation and provide surfaces for heterogeneous processes that modify the chemistry. Interpreting the complex chemistry occurring in wildfire plumes is critical to understanding air quality, especially under the changing fire regimes we see in many parts of the world. The goal of this session is to solicit recent studies that advance our understanding and interpretation of atmospheric chemical and physical processes occurring in wildfire plumes as well as their consequences on air quality, climate, and health. Organizers invite presentations covering small- to large-scale studies, and involving computational modeling and/or measurements.

SESSION GC004: Advancements in Observing and Modeling Processes and Coupled Feedbacks of the High-Latitude Earth Systems
Conveners: Wieslaw Maslowski, Milena Veneziani, Hailong Wang, and Wilbert Weijer
Advanced understanding and prediction of an amplified response of the high-latitude Earth systems (HLES) to climate change requires progress in observing and modeling local processes and feedbacks and their linkages to lower latitudes. One of the challenges for measurements is to collect data on individual processes as well as their impacts within the fully coupled HLES and upscale them to basin-scale. A key challenge for Earth system models (ESMs) is to realistically represent the range of spatiotemporal scales and to improve parameterization of critical processes and feedbacks for climate-relevant predictions.
Given the recent field activities and advancements in the fidelity of ESMs and machine learning/artificial intelligence techniques, this session invites presentations on HLES studies from local events/processes, through their roles in the coupled system, to hemispheric perspectives. Organizers also encourage presentations that advance understanding of polar extreme events, internal variability and forced trends, their predictability, and linkages to lower latitudes.
