my country's carbon satellite was successfully used for quantitative monitoring of urban carbon dioxide emissions for the first time

Pinwan, October 26th, according to People's Daily Online, from the Institute of Atmospheric Physics, Chinese Academy of Sciences, the carbon satellite research team of the institute and the Finnish Meteorological Institute team used the Chinese carbon satellite (TanSat) observations to quantitatively identify and calculate urban carbon emissions for the first time. This shows that China Carbon Satellite has the capability of city-level carbon emission monitoring. The research results were published online on October 25 in the SCI journal Advances in Atmospheric Science. The current assessment of the effectiveness of greenhouse gas emission reduction relies on inventory methods, and the use of carbon monitoring satellites to monitor global anthropogenic emissions is more advantageous. China Carbon Satellite is a near-polar sun-synchronous satellite with the main payload "High Spectral Resolution Atmospheric Carbon Dioxide Detector" and the auxiliary payload "Cloud and Aerosol Polarization Imager" on it. Among them, the main payload is the high spectral resolution atmospheric carbon dioxide detector, which uses the near-infrared/short-wave infrared solar radiation reflected from the earth to detect the content of carbon dioxide in the atmosphere. At the beginning of 2020, the National Remote Sensing Center of the Ministry of Science and Technology and the European Space Agency signed a cooperation agreement on greenhouse gas remote sensing monitoring, promoting the Chinese carbon satellite to join the European Space Agency's third-party satellite data application plan, which also shows that the Chinese carbon satellite and its observation data are gradually entering the world. With the support of this agreement, this study jointly applied the carbon dioxide observation data of the Chinese carbon satellite and the nitrogen dioxide observation data of the European Sentinel-5P satellite (Sentinel-5P). March 29, 2018) two cases, quantitatively calculated the correlation between anthropogenic carbon emissions and nitrogen dioxide. The calculated results are consistent with the results given in the emission inventory, demonstrating that the proportion of carbon dioxide and nitrogen dioxide emissions can be quantitatively monitored by the joint application of the collaborative observation of the Chinese carbon satellite and the European Sentinel satellite. At the same time, this also indicates that my country has the ability to monitor the carbon emissions of human activities in space.
