"During their in-orbit testing, these satellites demonstrated favorable application results across multiple areas, including ecological environment, forestry and grassland, geographic surveying, meteorology, agriculture and emergency disaster response, according to an official of the CNSA."
These satellites will provide critical data to help address global climate change and support China's carbon peak and carbon neutrality goals.
"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, according to the CNSA."
It can conduct extensive, continuous, dynamic, and round-the-clock monitoring of atmospheric fine particulate matter, pollutants, greenhouse gases, clouds, aerosols, and environmental elements like land surfaces and water bodies.
Additionally, it has achieved the first global round-the-clock high-precision detection of carbon dioxide column concentrations at 1 PPM.
The terrestrial ecosystem carbon monitoring satellite, also known as "Goumang" (named after the ancient Chinese god of spring, growth, and life), is the world's first remote sensing satellite for forest carbon sinks combining both active and passive observation methods, according to CNSA.
It uses various remote sensing techniques, including laser, multi-angle, multispectral, hyperspectral, and polarization methods, to detect vegetation biomass and productivity, and monitor atmospheric aerosol distribution.
It also meets the needs of geographic surveying, disaster assessment, and agricultural remote sensing.
"Goumang" has enabled quantitative remote sensing detection of forest vegetation height, biomass, and chlorophyll fluorescence, enhancing forest carbon sink monitoring capabilities globally.
CNSA plans to further explore the satellite application scenarios, improve overall application effectiveness, and promote the sharing and utilization of satellite data resources.
China launched the atmospheric environment monitoring satellite on April 16, 2022, and the terrestrial ecosystem carbon monitoring satellite on Aug. 4, 2022, both from the Taiyuan Satellite Launch Center in northern Shanxi Province.
