Dear Colleagues,
We are excited to announce the upcoming AMS 2026 meeting in Houston and invite you to submit an abstract to our session for presentation on aerosol pollution, weather modification, and climate intervention. We look forward to having you share your work and hope to see you at the conference!
Best,

Cloud and precipitation responses to aerosol pollution, weather modification, and climate intervention
(Joint between Aerosol Cloud Climate Interactions and Cloud Physics Symposiums)
Aerosol-cloud interactions (ACI) from anthropogenic pollution and biomass burning make a large but highly uncertain contribution to present-day global climate forcing. ACI are also intentionally leveraged to modify precipitation through cloud seeding and are being considered for potential climate intervention strategies, including the brightening of marine clouds and the thinning of high-altitude cirrus clouds. Although these categories differ, with unintentional impacts in the former and intentional modification in the latter two, they share common physical processes and sources of uncertainty.
Moreover, while cloud seeding has historically been deployed at the watershed scale to enhance precipitation, some regions are now pursuing larger-scale efforts aimed at broader regional impacts on water resources, bringing the operational scale closer to that of inadvertent aerosol-cloud interactions and climate intervention efforts. Across all three areas, a key challenge remains: understanding cloud responses to aerosol perturbations across a range of scales, the dependence of these responses on background aerosol and meteorological conditions, and the feedbacks between cloud changes and aerosol properties.
This session invites presentations on aerosol-cloud-precipitation processes across the contexts of climate forcing, regional precipitation enhancement, and regional to global climate intervention. We welcome contributions from numerical modeling studies, analyses of observations of deliberate cloud seeding (such as the SNOWIE campaign or CAARE facility), and studies of inadvertent analogues (such as ship tracks and contrails). The session aims to bring together scientists from the weather and climate research communities to foster dialogue in an area of common interest
