The China National Space Administration(CNSA) has officially announced the operation of two climate monitoring satellites. climate and carbon monitoring satellites and carbon monitoring satellites with state-of-the-art technologies. These satellites will monitor the atmospheric environment and record the carbon flux of the Earth’s ecosystem for observation and analysis of global climate change.
Advanced climate and carbon monitoring satellites
During the in-orbit testing phase, these satellites have demonstrated exceptional performance in a variety of applications, including ecosystem assessment, forest and rangeland resource management, geographic topography, meteorology, agriculture and natural disaster response.
According to CNSA, the data collected will be critical for China to achieve its goals of achieving positive carbon indicators and moving towards carbon neutrality. carbon neutrality.
The atmospheric monitoring satellite is the first in the world to incorporate active laser detection technology, integrating advanced techniques such as hyperspectral, multispectral and high-precision polarization. This innovation allows continuous observation, covering fine atmospheric particles, greenhouse gases, clouds, aerosols, as well as observation of the earth’s surface and bodies of water. In addition, for the first time, a global and accurate detection of carbon dioxide in the atmosphere has been achieved, with an accuracy of up to 1 part per million.
“Goumang”: Innovation in forest carbon monitoring
The second satellite, known as “Goumang”, after the ancient Chinese god of spring, is tasked with remote sensing of forest carbon sinks. This is the first satellite to unify active and passive observation methods for measuring vegetation biomass and productivity, as well as monitoring the distribution of aerosols in the atmosphere.
The advanced technology of the“Goumang satellite” includes laser, multi-angle, multi-spectral, multi-spectral, hyperspectral and polarization techniques, enabling it to perform quantitative remote sensing of vegetation height, biomass and chlorophyll fluorescence, enhancing the monitoring capabilities of forest carbon sinks both in China and globally.
The CNSA has expressed its intention to continue exploring new applications for these satellites, improving the efficiency of data collection and use, and promoting the sharing of satellite data resources. These efforts underscore China’s commitment to combating global climate change and promoting advanced technologies for environmental monitoring.
The first satellite was launched on April 16, 2022, while the Earth ecosystem carbon monitoring satellite was launched into orbit on August 4, 2022. Both were launched from the Taiyuan Satellite Launch Center in Shanxi province.
