abstract = "This work uses the number concentration-effective diameter
phase-space to test cloud sensitivity to variations in the aerosol
population characteristics, such as the aerosol size distribution,
number concentration and hygroscopicity. It is based on the
information from the top of a cloud simulated by a
bin-microphysics single-column model, for initial conditions
typical of the Amazon, using different assumptions regarding the
entrainment and the aerosol size distribution. It is shown that
the cloud-top evolution can be very sensitive to aerosol
properties, but the relative importance of each parameter is
variable. The sensitivity to each aerosol characteristic varies as
a function of the parameter tested and is conditioned by the base
values of the other parameters, showing a specific dependence for
each configuration of the model. When both the entrainment and the
bin treatment of the aerosol are allowed, the largest influence on
the droplet size distribution sensitivity was obtained for the
median radius of the aerosols and not for the total number
concentration of aerosols. Our results reinforce that the cloud
condensation nuclei activity can not be predicted solely on the
basis of the w/Na supersaturation-based regimes.",
