Description

technical field [0001] The invention belongs to the field of air pollution monitoring, in particular to a ball-borne atmospheric boundary layer NO 2 vertical detection system. Background technique [0002] In recent years, the pollution of the atmospheric boundary layer (300-1000 meters above the land) has become a major obstacle that seriously restricts the country's economic development and people's health. Among them, NO 2 It is one of the most important precursors of photochemical pollutants such as ozone and secondary aerosol, and is the main source of acid rain, acid fog and photochemical smog, endangering human health and safety. Therefore, it is urgent to develop atmospheric boundary layer NO 2 The advanced high-resolution vertical detection technology breaks through the complexity and stability of high-altitude detection, and detects NO in the atmospheric boundary layer in real time. 2 Concentration distribution, to achieve online monitoring and evaluation of air...
