This National Science Foundation project grant of $582,172 will fund the development of optical classification models for ambient aerosols using machine learning. Awarded under the Geosciences program of the Division of Atmospheric and Geospace Sciences, this three-year project beginning March 2022 aims to build tools that can differentiate aerosol types based on measured optical properties without prior assumptions. The University of Georgia Research Foundation will receive funding to identify clusters of aerosols with distinct optical signatures, develop classification models based on these clusters, and translate the models for use with lower-cost sensors. Outreach is also included to engage students in learning about atmospheric aerosols firsthand. The products will provide constraints for climate modeling by improving how aerosols are treated.
