Special sessions for EAC 2024
Characterization and impact of aerosol emissions from aviation (WG1)
Aviation emissions are not limited to greenhouse gases like CO2 or water but include as well other gases like nitrogen oxides (NOx) or sulfur oxides (SOx) and volatile and non-volatile particulate matter (vPM and nvPM respectively). Recent studies show that approximately 50-75% of aviation’s climate impact is caused by non-CO2 emissions, with the main contribution coming from contrails and NOx emissions. while these studies have improved our knowledge on this topic, a number of open questions still need to be answered to assess the impact of aviation on climate. This session aims to provide an overview of this topic’s state of the art.

Oxidative potential of aerosol particles and health risks (WG2 & WG 4)
The chemical reactivity of airborne particles and their ability to cause oxidative stress in biological organisms is an increasingly studied topic. The session invites talks on the mechanisms by which aerosols interact with environmental factors and human health, the impact of oxidative stress due to aerosols on respiratory and cardiovascular diseases, and measurement techniques for quantifying the oxidative potential of particulate matter and its components.
The Po Valley open air-laboratory: lessons learned and current challenges
We invite talks on the findings from research conducted in the Po Valley site, a well-known research station in a region known for its unique meteorological and topographical conditions affecting air quality and atmospheric chemistry.

Conveners: Nicolas Bruffaerts (), Sophie Erb ()
Aerosol remote sensing (WG2)
We invite talks on the methodologies and advancements in the use of satellite and ground-based remote sensing technologies to observe and analyze aerosol particles in the Earth’s atmosphere. This includes the development of new sensors and algorithms for aerosol characterization, data assimilation techniques, and the role of remote sensing in understanding the impacts of aerosols on climate, weather, and human health on a global scale.
