The Research on the CCN Activation of Aerosols in Shanghai
The cloud condensation nuclear (CCN) is the suspended particle that the atmospheric water could condensate on it to form the cloud droplet and it is an important component of atmospheric aerosols. The CCN can affect the atmospheric condition largely by reflecting and absorbing the radiation of the sunlight. It plays a vital role in the global water recycle as well. The research on the CCN activation of aerosols in Shanghai was carried in September to December, 2010 and we found that it was the aerosols with a diameter between 100nm and 150nm that contributed mostly to the CCN number concentration in Shanghai. Chemistry component contained in those aerosols played an important role in the CCN activation. We found that the SO4 and NH4 ions were the main inorganic component which had high relevance and high contribution weight to the CCN activation, followed by NO3. We also found that some other factors such as the meteorology、O3、NOX、humidity and temperature were important indicators for CCN variation.
