| description | Measurements of cloud condensation nuclei (CCN) concentrations, single
particle composition and size distributions at a high-elevation research
site from March 2011 are presented.
<br><br>
The temporal evolution of detailed single particle composition is compared
with changes in CCN activation on four days, two of which include new
particle formation and growth events. Sulfate-containing particles dominated
the single particle composition by number; biomass burning particles, sea
salt particles, and particles containing organic components were also
present. CCN activation largely followed the behavior of the
sulfate-containing particle types; biomass burning particle types also
likely contained hygroscopic material that impacted CCN activation. Newly
formed particles also may contribute to CCN activation at higher
supersaturation conditions. Derived aerosol hygroscopicity parameters from
the size distribution and CCN concentration measurements are within the
range of previous reports of remote continental kappa values. |
