DESCRIPTION: The goal of this collaborative project is to examine local and remote climate impacts of regional emission perturbations to aerosol or precursor emissions (sulfur dioxide, black carbon and organic carbon, together and separately), which are regulated for public health reasons under air pollution policy in many world regions and can induce regional and global climate changes over the next several decades. We aim to advance understanding of the magnitude, spatial pattern and statistical significance of local and remote climatic reponses to changes in regional emissions of aerosols and precursors. Knowledge generated through this study can inform the climate assessment community.
