Haze has become a major environmental problem in Guanzhong Region of Shaanxi Province. Aerosol is one of the most uncertain factors in the climate change study, and many observations and researches worldwide have paid much attention to its climate effect. The overall design and observation content of the aerosol observation platform of atmospheric laboratory test base in Qinling Mountains are introduced in this paper. This platform has the ability of field data collection, remote monitoring, data transmission, humancomputer interaction, data storage and quality inspection, data inversion, product display and other functions. It integrates observation, calculation and query, which can provide data support for the research and development of environmental and meteorological service technology.
