                         developing in polluted and clean conditions in the biomass-burning 
                         season of the Amazon region are examined, with special attention 
                         to the spectral dispersion of the cloud droplet size distribution 
                         and its potential impact on climate modeling applications. The 
                         dispersion effect has been shown to alter the climate cooling 
                         predicted by the so-called Twomey effect. In biomass-burning 
                         polluted conditions, high concentrations of low dispersed cloud 
                         droplets are found. Clean conditions revealed an opposite 
                         situation. The liquid water content (0.43 ± 0.19 g m\−3) is 
                         shown to be uncorrelated with the cloud drop number concentration, 
                         while the effective radius is found to be very much correlated 
                         with the relative dispersion of the size distribution (R2 = 0.81). 
                         The results suggest that an increase in cloud condensation nuclei 
                         concentration from biomass-burning aerosols may lead to an 
                         additional effect caused by a decrease in relative dispersion. 
                         Since the dry season in the Amazonian region is vapor limiting, 
                         the dispersion effect of cloud droplet size distributions could be 
                         substantially larger than in other polluted regions.",
