The aerosol model is generally adopted to describe typical aerosol properties in a specific region, and it is an indispensable input parameter in radiative transfer calculations.
According to a recently study, based on data acquired at aerosol robotic network (AERONET) sites across China, researchers led by Prof. SUN Xiaobing from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences developed eight aerosol types to help obtain better understanding of earth atmosphere.
The researchers used cluster analysis to obtain eight aerosol models with the data. After analyzing the seasonal variations of the above aerosol types in the selected areas, they found that dust aerosols mostly appeared in spring, and high moisture absorption aerosols appeared mostly in summer. The frequency of carbonaceous aerosols reaches the maximum in winter.
This study presents a better understanding for not only physical and chemical properties, but also temporal and spatial distribution of aerosols in China.
