China’s atmospheric environment monitoring satellite and terrestrial ecosystem carbon monitoring satellite have officially commenced operation, the China National Space Administration (CNSA) announced on Thursday.
During their in-orbit testing, these satellites demonstrated significant application results across multiple sectors, including ecological environment, forestry and grassland management, geographic surveying, meteorology, agriculture, and emergency disaster response, according to a CNSA official.
The two satellites are poised to provide crucial data to effectively address global climate change and support China’s goals of achieving carbon peak and carbon neutrality.
The atmospheric monitoring satellite is the world’s first to utilize active laser detection, employing a combination of active laser, hyperspectral, multispectral, and high-precision polarization techniques for comprehensive observation, as stated by the CNSA.
This satellite is capable of conducting extensive, continuous, dynamic, and round-the-clock comprehensive monitoring of atmospheric fine particulate matter, pollutants, greenhouse gases, clouds, aerosols, as well as environmental elements such as land surfaces and water bodies.
Additionally, it has, for the first time, achieved global round-the-clock high-precision detection of carbon dioxide column concentrations at 1 part per million.
