Aerosol particle light scattering at a perturbed mid-latitude continental northern hemisphere site and its dependence on relative humidity, wavelength of light, particle size and composition
Abstract
dc:descriptionRecent model predictions indicate that sulfate aerosol particles cause radiative forcing of the same magnitude but of opposite sign than the forcing caused by anthropogenic greenhouse gases. The spatial and temporal variability of parameters used in the models are highly uncertain resulting in uncertain model predictions of the aerosol radiative forcing. Such parameters related to aerosol particle properties and direct radiative forcing are: the hygroscopic growth factor (f(RH)), the upscatter fraction (β), and the mass scattering efficiency, (α). These three parameters can be estimated from regional measurements of total light scattering and back-scattering coefficients as functions of relative humidity, particle composition and size, and wavelength of light.
