China Gansu Network, November 19 (Northwest Corner, China Gansu Network reporter Shen Wengang) Recently, the National Natural Science Foundation of China announced the list of projects funded under the 2024 National Major Scientific Research Instrument Development Program (Free Application). The project "Development of an Advanced Multi-Excitation Wavelength Full-Spectrum Bioaerosol Lidar," led by Professor Huang Zhongwei from the College of Atmospheric Sciences at Lanzhou University, has been approved for funding. The direct funding is 7.62 million yuan, with a research period of 5 years.
The project addresses cutting-edge issues in the climate and environmental health effects of biological aerosols, as well as major national needs such as epidemic prevention and control and biosafety. Led by Lanzhou University and jointly submitted by Beijing ZhuoLai Laser Technology Co., Ltd., the project aims to overcome key technical bottlenecks in multi-wavelength laser excitation, full fluorescence spectroscopy detection, and accurate inversion of biological aerosols. It seeks to develop a multi-excitation wavelength full-spectrum biological aerosol lidar system, forming a significant scientific facility with independent intellectual property rights in China. This will enable "multi-dimensional CT scanning" of biological aerosols at different altitudes. The project's outcomes will provide critical equipment for real-time and accurate detection of vertical distribution of atmospheric biological aerosols, offering important application value in fields related to biological aerosol monitoring and early warning, including atmospheric science, environmental science, epidemic prevention and control, and biosafety.
This project is the first major instrument development project approved by Lanzhou University's Lidar Atmospheric Remote Sensing Team after 17 years of effort. It is also the third national major scientific research instrument development project (free application) to be approved, fully demonstrating the university's strong capabilities in developing high-end instruments for atmospheric remote sensing. This initiative represents the university's concrete practice of focusing on national strategic needs, accelerating basic research, and building key national assets.
The National Major Scientific Research Instrument Development Project is a significant landmark project established by the National Natural Science Foundation of China. It targets the frontiers of science and national needs, guided by scientific objectives. The project funds the development of original scientific instruments and core components that play a crucial role in promoting scientific progress, exploring natural laws, and expanding research fields, thereby enhancing China's original innovation capabilities.
It is reported that the Lanzhou University Laser Radar Atmospheric Remote Sensing Team has long been dedicated to the research of dust aerosols and biological aerosols using laser remote sensing. They have successively developed China's first multi-band Raman-fluorescence lidar, dual-wavelength polarization Raman lidar, three-dimensional scanning environmental monitoring lidar, and airborne visibility lidar. These technologies have been granted 12 national invention patents and 2 international invention patents, successfully achieving the transformation of scientific research results and winning the First Prize for Scientific and Technological Progress in Gansu Province.
