Abstract

A comprehensive investigation of the processes regulating tropospheric aerosol distributions, their optical properties, and their radiative effects in conjunction with verification of their simulated radiative effects for past conditions relative to measurements is needed in order to build confidence in their estimates of the projected impacts on future climate. This study aims at addressing this issue through a systematic investigation of changes in anthropogenic emissions of SO2 and NOx over the past two decades in the United States, the consequent changes in anthropogenic aerosol loading in the North American troposphere, and subsequent impact on regional radiation budgets.
