It is now well established that aerosols, by scattering and absorbing solar radiation, affect the terrestrial heat engine. Depending on the net relfectivity and absorptivity of the haze column and on the surface albedo, the net effect could be a cooling or a warming. But better understanding of the influence of aerosols is handicapped by lack of data and by the fact that their composition and distribution is highly variable in space and time. For the same reasons, the incorporation of aerosols in climate models is usually rudimentary. / We have in-situ measurements of the vertical profile and size distribution of aerosols ($>$0.09 $ mu$m in radius) taken over several places in eastern Canada at different times of the year. These data have been incorporated in a simple multi-layer radiative transfer model to estimate the effects of aerosols on the local radiation budget. A broad range of refractive indexes has been used and the increase of the particles size with the relative humidity is included.
