"Multi-target greenhouse gas measurement technology" project progress inspection meeting was held
[ China Instrument Network Instrument R&D ] Recently, in order to understand the progress and achievements of the key special project “multi-target greenhouse gas measurement technology†project of the national key R&D project “Research on Genesis and Control of Atmospheric Pollutionâ€, the project related undertaker and participating units participated in the “ Multi-purpose greenhouse gas measurement technology "project progress inspection meeting.
In July 2017, the “multi-target greenhouse gas measurement technology†project led by the greenhouse gas business office of China Meteorological Administration’s Meteorological Observation Center began implementation with an implementation period of 3.5 years. The Chinese Academy of Sciences, the National Satellite Meteorological Center, the Beijing Institute of Metrology and Detection, and the Nanjing University of Information and Technology have jointly participated in this project.
The “multi-target greenhouse gas measurement technology†project mainly addresses the issues of poor equipment accuracy, backward technology, and equipment reliance on imports for greenhouse gas monitoring in China. It closely focuses on building China’s atmospheric greenhouse gas monitoring network and serving the urgent needs of climate change. Demand, high-sensitivity phase-shift axis integration cavity spectroscopy, high-spectral resolution infrared laser heterodyne spectroscopy, phase-shift distance measurement on-line calibration, greenhouse gas flux anti-pollution long-range absorption spectroscopy, high-accuracy tunability Diode laser modulation absorption spectroscopy technology, high-intensity aerosol near-infrared spectral hyperspectral greenhouse gas satellite inversion algorithms and other key technologies, research and development, including clean air greenhouse gas high-precision monitoring devices, greenhouse gas emissions total on-line monitoring device, The greenhouse gas flux monitoring device of typical ecosystems and the multi-objective greenhouse gas measurement system of atmospheric greenhouse gas vertical profile monitoring devices are implemented and industrialized.
The Beijing Institute of Metrology and Detection, as the main undertaking unit, cooperates with enterprises to jointly undertake the research and development and application demonstration of the greenhouse gas emission on-line monitoring system, and is responsible for the establishment of the detection method for the greenhouse gas on-line monitoring system and the formulation of the quality assurance specification. The research content is to develop on-line monitoring systems for greenhouse gases such as methane, carbon monoxide, and carbon dioxide, and establish evaluation methods and quality assurance.
At present, the Beijing Institute of Metrology Institute of Environmental Energy has long paid attention to and researched the measurement and evaluation technology of ecological environment monitoring equipment. It has established a greenhouse gas monitoring system evaluation platform at the domestic advanced level, and successively developed methane and carbon monoxide in the evaluation of greenhouse gas monitoring technology. The preparation of greenhouse gas reference materials such as carbon dioxide, multi-range gas dilution equipment, multi-functional gas simulation warehouses, and open gas monitoring equipment online calibration equipment have been prepared to produce different concentrations of bottled standard gas with the highest dilution accuracy. The ±0.5% capability is used to simulate atmospheric conditions under different conditions. It can be used in laboratory and online metrology inspection and evaluation of open inspection equipment.
With this platform, the measurement and evaluation capabilities of other gas on-line monitoring devices will be further expanded. At the inspection meeting, the greenhouse gas monitoring system evaluation platform was highly recognized by the project's main undertaking unit and participating experts.
After the completion of the “multi-target greenhouse gas measurement technology†project, it will promote China’s research on the quantitative certification of terrestrial carbon revenue and expenditure, the potential and rate of carbon enrichment, and the technology and measures to increase foreign exchange, so as to improve China’s response to climate change and carbon emission reduction. The right to speak in international negotiations. At the same time, it will significantly increase China's self-discovery capacity of greenhouse gases and provide strong technical support for the establishment of a new generation of China's atmospheric greenhouse gas monitoring network.
