Science and Technology Daily News (Reporter Wu Changfeng) The reporter learned from the Hefei Institute of Material Science of the Chinese Academy of Sciences (hereinafter referred to as the Hefei Research Institute of the Chinese Academy of Sciences) that the national major science and technology infrastructure aerial remote sensing system was constructed by the Chinese Academy of Sciences and participated in the development of the Hefei Research Institute of the Chinese Academy of Sciences. It has passed national acceptance and put into formal operation recently.
The Acceptance Committee believes that the facility has built my country’s current aviation remote sensing platform and scientific experiment platform with the strongest comprehensive capabilities. The comprehensive performance of the facility has reached the domestic leading and international advanced level. It is of great significance to promote my country's aviation remote sensing technology and application to achieve major original breakthroughs.
Among them, the "Environmental Atmosphere Composition Detection System", which was the first of more than ten remote sensing payloads to be delivered and received overall praise, was undertaken by the Anguang Institute of Hefei Research Institute, Chinese Academy of Sciences.
It is reported that the large-scale scientific installation aerial remote sensing system, known as the “heavy instrument of the country,” is a major national science and technology infrastructure project approved by the National Development and Reform Commission. An aviation remote sensing data comprehensive processing and management system with comprehensive remote sensing multi-source information data processing capabilities, as well as an aviation remote sensing system complex building in Beijing and a hangar at Yingkou Airport in Liaoning.
The system can obtain multiple types of remote sensing data including land, ocean, and atmosphere. The service area can cover agriculture, forestry, ocean, surveying and mapping, environment, disasters, etc., and can provide scientific experiment mode, cruise mode, emergency response mode and orders Models and other types of aerial remote sensing services.
The "Environmental Atmospheric Composition Detection System" developed by the Anguang Institute of Chinese Academy of Sciences Hefei Research Institute is an airborne environmental atmospheric composition detection system for quickly acquiring regional environmental atmospheric monitoring parameters. It consists of four independent hardware subsystems, namely atmospheric environmental lasers. Radar, differential absorption spectrometer, multi-angle polarization radiometer and main control management system, using the combination of active and passive optical remote sensing detection technology, real-time acquisition and recording of the optical properties of atmospheric aerosols within a certain range on the flight path and below the flight altitude as the flight And microphysical properties, the concentration of atmospheric pollutants such as sulfur dioxide, nitrogen dioxide, and ozone, the spatial distribution of cloud conditions and the three-dimensional information of the cloud state, the main control program can determine the work or combination of subsystem detection equipment according to the actual needs of detection, It can also cooperate with other airborne systems to obtain correction information for atmospheric aerosols and clouds.
The comprehensive atmospheric environmental information obtained is mainly used in the fields of atmospheric cloud and aerosol characteristics research, atmospheric environmental science and meteorological science research, and emergency response to air pollution emergencies.
Several flight experiments of the environmental atmospheric composition detection system have shown that the system can provide comprehensive observation methods for regional, frequent, and catastrophic atmospheric environmental pollution measurements, and for understanding the quantitative distribution and the evolution of aerosol and atmospheric environmental quality in my country. Understanding the microphysical properties and classification of atmospheric environmental aerosols provides very important technical support. The system can be used as an effective supplement to ground monitoring equipment or spaceborne equipment monitoring, and can provide data support for the location and investigation of pollution sources. It is a powerful means to quickly obtain regional pollution information and study pollution processes.Keywords:
