The Aerosol–Climate Interactions group at the University of California, Los Angeles is seeking a postdoctoral scholar in Arctic climate dynamics and climate intervention . The project examines the climate response to targeted wintertime polar cooling, with a focus on mixed-phase cloud thinning and its impacts on the Arctic and global climate system. This research is part of a Simons Foundation-supported project. The scientific goals include understanding effects on sea ice , hydrology , AMOC-relevant ocean stratification , time of emergence , and climate variables relevant to Arctic communities. The broader group studies aerosol–radiation–cloud–climate interactions , especially the role of desert dust aerosols in cloud microphysics and Earth’s energy balance. The position offers substantial intellectual ownership and access to UCLA and NCAR high-performance computing resources, with collaboration opportunities involving colleagues at UCLA, Scripps, and the University of Maryland. The post is well suited to researchers with interests in climate dynamics , aerosol-cloud interactions , climate modeling , and atmospheric physics. Eligibility and timing: a summer 2026 start date is preferred. U.S. citizenship or permanent residency is not required. Applications received by 2026-05-20 will receive full consideration, and applications will continue to be reviewed until the position is filled. How to apply: Read the full job advertisement for application instructions and submit the required materials through the linked posting.
