Short summary
Black carbon (BC) particles can have deleterious health consequences and impact regional and global climate. We aim to observe how processing near highways and longer timescale aging in an urban plume affect BC physical properties including coatings. Measurements in distinct regions of the Los Angeles Basin indicate that health-relevant physical properties can change within 100 m of the freeway. Climate-relevant properties downwind of Los Angeles depend on day of week and overall meteorology.
