Researchers Study Aerosols Over California: Findings May Clarift Regional pollution Controls
From Phys Org:
For the first time ever, these researchers have characterized the relative, direct influence of different aerosol species on seasonal atmospheric warming and cooling over California using supercomputers at the Department of Energy’s National Energy Research Scientific Computing Center (NERSC) and at PNNL. The scientists found that aerosols have a net cooling effect on California’s atmosphere, but individual species contribute differently. While sulfates contributed the most to cooling, black carbon particles, or soot, were responsible for up to 95 percent of countervailing warming.
