[ China Instrument Network Instrument R&D ] Recently, the National Natural Science Foundation of China organized experts to conduct a special "multi-band multi-atmospheric component active and passive integrated detection system" (hereinafter referred to as APSOS) for the development of national major scientific research instruments and equipment under the auspices of the Institute of Atmospheric Physics of the Chinese Academy of Sciences. The project was completed and accepted. Deputy Director of the Fund Committee Hou Zengqian, Deputy Director of the Department of Earth Science, Wang Weidong, Director of the Finance Bureau Wang Wei, Director of the Planning Bureau Zhang Xiaobin, Director of the Chinese Academy of Sciences and the Su Chi business, and other leaders of the Fund Committee, members of the acceptance expert group, members of the project team and More than 80 people from relevant units and departments attended the meeting, and Wang Yidong presided over the project acceptance meeting.
First of all, Hou Zengqian delivered an important speech on the acceptance work of major instrument development projects. Wang Hao and Zhang Xiaobin introduced the relevant requirements for project financial acceptance and technical file acceptance. The director of the Institute of Atmospheric Sciences of the Chinese Academy of Sciences, Zhu Jiang, said on behalf of the project support unit that he would fully cooperate The project acceptance work.
The leader of this acceptance expert group is served by the Wanxing Academy of Geology and Geophysics, Chinese Academy of Sciences. At the acceptance meeting, the project leader Lu Daren represented 7 research institutes (Chinese Academy of Sciences, Wuhan Institute of Physics, Anhui Institute of Optics, Purple Mountain Observatory, University of Science and Technology of China, Wuhan University and Anhui Si Chuang Electronics Co., Ltd.) The completion of instrument development and representative innovations. Researcher Gao Yuchun, head of the instrument testing expert group, introduced the on-site test in Yangbajing, Tibet during the period of June 13-14, 2018, and read out the instrument test conclusions. Researcher Li Yinghua of the project supervision expert group reported on the on-site supervision since the implementation of the project. Experts from the Financial Acceptance Group and the Technical Archives Group conducted on-site review work, and the financial and file acceptance opinions were read out by the team leader Wang Derui and Zhang Shilin respectively.
APSOS consists of integrated integration and inversion verification platform and combined telescope system, aerosol-cloud-water vapor detection laser radar, atmospheric temperature wind field detection laser radar, ozone detection laser radar, pollution gas detection laser radar, carbon dioxide detection laser radar, terahertz The superconducting radiation spectrometer and the W-band cloud measuring radar are composed of units. The system was successfully deployed in Yangbajing, Tibet (4300 m above sea level) in October 2017 after conducting joint testing in Huainan, Anhui and Qinghai Delingha. The APSOS project team has successfully completed the instrument development task. The technical indicators of the system have met the requirements of the task book. The APSOS system has become the most comprehensive atmospheric observation system with the highest altitude and the most comprehensive detection means in the world, and has begun to obtain important scientific data on the Qinghai-Tibet Plateau.
The combined telescope of the system utilizes multi-fiber multi-wavelength spatial splitting technology to achieve 2 m equivalent aperture and multiple sets of lidar sharing; aerosol-cloud-water vapor detection laser radar uses 3 wavelengths to emit 6-wavelength receiving mode to achieve aerosol , cloud and water vapor detection; atmospheric temperature wind field detection laser radar realizes 5-151 km altitude atmospheric temperature and 10-60 km, 80-110 km altitude atmospheric wind field simultaneous detection; ozone detection laser radar achieves 5-50 Simultaneous detection of tropospheric and stratospheric ozone at the height of km; the polluted gas detection lidar simultaneously obtains the distribution of nitrogen dioxide and sulphur dioxide in the range of 0.1-3 km; the carbon dioxide detection lidar obtains carbon dioxide changes in the range of 0.1-3 km. Characteristics; terahertz superconducting radiation spectrometer is the first time in China to apply terahertz technology to the field of ground-based atmospheric detection; W-band cloud-based radar has raised the ground-based cloud-measuring radar from Ka-band to W-band for the first time in China.
The APSOS project team has been authorized to apply for 7 national invention patents, and has completed a complete independent intellectual property rights system; published 35 papers in academic papers; and added the National Natural Science Outstanding Youth Fund winners in talent training 1 People, trained a postdoctoral, 19 doctoral students and 11 master students, formed a technical team to independently develop atmospheric detection equipment.
At the acceptance meeting, the project acceptance expert group affirmed the fruitful achievements of the project team in the development of large-scale scientific instruments, and unanimously agreed that the project passed the acceptance. The smooth implementation and acceptance of the APSOS project indicates that China has mastered the key technologies of the international frontier in the field of atmospheric exploration research, and has the integrated capability of integrated systems and the independent monitoring capability of the atmospheric space environment, providing further research on atmospheric scientific research in the Qinghai-Tibet Plateau. Strong technical support.
