J1A Wildfire Influence on Aerosol, Cloud, and Climate I (Joint between the 17th Symposium on Aerosol Cloud Climate Interactions and the 27th Conference on Atmospheric Chemistry)

Monday, 13 January 2025: 8:30 AM-10:00 AM
215 (New Orleans Ernest N. Morial Convention Center)
Hosts: (Joint between the 17th Symposium on Aerosol Cloud Climate Interactions; and the 27th Conference on Atmospheric Chemistry )
Cochairs:
Qi Tang; Kristina Pistone, NASA Ames, Moffett Field, CA; Jeffrey D. Mirocha, LLNL; David A. Peterson, NRL, Monterey, CA; Yingxi Rona Shi, NASA Goddard Space Flight Center, Greenbelt, MD and Ziming Ke, Texas A&M University, Department of Atmospheric Sciences, College Station, TX

Wildfires have intricate interactions with Earth's climate system. Under climate change, wildfire risk rises due to shifts in temperature, moisture, wind, land use, and vegetation. Wildfire frequency and intensity have notably increased, particularly in the western US during recent decades. This session focuses on recent advances in understanding the impact of wildfires on aerosols, clouds, and climate. We welcome a wide range of contributions related to wildfire, such as numerical modeling with global, regional, or climate models; in-situ and remote sensing measurements; satellite retrievals; climatology, trend, or case studies; prescribed fire; and theoretical studies leading to better understanding of driving mechanisms.
