Collaborative Research: Hygroscopic Properties of Aerosol Organics NSF Atmospheric Chemistry Program, 2009-2012 Aerosols affect the Earth’s radiation balance directly by scattering sunlight and indirectly through their role as cloud condensation nuclei (CCN). An increase in the number of CCN leads to more numerous but smaller cloud droplets and increased cloud albedo. Current estimates of direct and indirect effects, -0.9 to
