Atmospheric aerosols are a variable but important contribution to the global climate. Their effects on the optical behavior of the atmosphere directly influence the radiation budget and the analysis of remotely sensed data. Identification of the radiative impact from specific aerosols would add to the growing understanding of general aerosol radiative properties, and in turn our understanding of the global climate. Data, taken as part of the Atmosphere/Ocean Chemistry Experiment (AEROCE), was used to analyze the radiative characteristics of specific aerosols over Miami (Florida), Bermuda, and Barbados from August 1993 to December 1995. Unique radiative signatures of specific aerosols are presented based on analysis of correlations between measured aerosol optical depth (AOD) and the associated Angstrom exponent , and direct sampling of aerosol concentrations at the surface.
