The session welcomes contributions on aerosol observations and their interactions with clouds, solar radiation, and climate, with a focus on both ground-based and satellite-based measurements. It aims to highlight recent advances in aerosol measurement techniques, harmonization efforts, and calibration/validation studies, especially those supporting long-term consistency and comparability across networks.
Key topics include the observation of aerosol optical properties, results from field campaigns, radiative transfer in cloud-free and cloudy atmospheres—including 3D modeling aspects—and the validation of satellite aerosol products using ground-based networks. Studies on aerosol impacts on solar radiation and energy production and aerosol assimilation into models, are also encouraged.
Particular emphasis is given to contributions from the Harmonia COST Action (AEutopean network of 150 scientists), which supports global harmonization of aerosol measurements, and the ACTRIS community, including the Calibration of Aerosol Remote Sensing (CARS) group. However, the session is open to all researchers working on aerosol measurements, modeling, and satellite product validation.
Overall, the session aims to promote collaboration and knowledge exchange to improve the quality and increase the use of aerosol data for climate, atmospheric, and solar energy applications.
