Atmospheric environment monitoring satellites successfully launched to reduce pollution and carbon

 

The satellite will realize the active laser detection of CO2 and the active and passive combined detection of atmospheric fine particles in the world.
At the same time, it can support the application of remote sensing monitoring in meteorology, agriculture and rural areas
.

 

The Atmospheric Environment Monitoring Satellite operates in a sun-synchronous orbit of 705km, and is equipped with 5 payloads including atmospheric detection lidar, high-precision polarization scanner, multi-angle polarization imager, ultraviolet hyperspectral atmospheric composition detector and wide-field imaging spectrometer.
, the weight of the whole star is about 2.
8 tons, and the design life is 8 years
.
Among them, atmospheric detection lidar uses dual-system laser technology to detect aerosols and CO2 internationally, and uses active methods to finely detect the total amount of atmospheric CO2 columns to obtain large-scale and high-precision CO2 concentration change information and aerosol scattering coefficient profiles.
The vertical distribution information such as line, extinction coefficient profile, optical thickness, boundary layer height, etc.
, makes up for the deficiencies of previous passive observations
.
The combined observation of a high-precision polarization scanner and a multi-angle polarization imager can obtain polarization information of clouds and aerosols from multiple angles, which can be used to invert the spatial and temporal distribution information of global atmospheric aerosols and clouds.
The observation width is greater than 1800km.
Quantitative detection of near-surface fine particles can be achieved through the collaborative observation and application with the atmospheric detection lidar load
.
The ultraviolet hyperspectral atmospheric composition detector can obtain information on the concentration of gaseous pollutants such as O3, NO2 and SO2, with a width greater than 2300km, and has the ability to cover the globe once a day
.
The wide-field imaging spectrometer can obtain multi-spectral information of the land surface and atmosphere in the spectral range from visible light to long-wave infrared (0.
415-12 μm)
.

 

　　The successful launch of the atmospheric environment monitoring satellite will further enhance China's remote sensing monitoring capabilities for CO2 and atmospheric pollutants
.
In terms of coping with global climate change, the active laser high-precision, all-day detection of CO2 on a global scale has been realized, and the detection accuracy has reached an excellent level, which can provide accurate remote sensing data support for CO2 distribution and response to climate change; in terms of remote sensing monitoring of atmospheric environment, It has quantitative remote sensing monitoring capabilities for global fine particulate matter (PM2.
5), gaseous pollutants, clouds and aerosols, as well as large-scale and highly dynamic remote sensing monitoring capabilities for air pollution sources such as industrial emissions and biomass burning.
In terms of remote sensing monitoring of water environment, quantitative remote sensing monitoring of algal blooms, water quality, aquatic vegetation in inland large water bodies, as well as red tides, oil spills, and water quality in offshore areas can be realized; in natural ecological remote sensing In terms of monitoring, quantitative remote sensing inversion of key parameters of the ecosystem can be achieved, providing important data support for national and regional ecological environment status surveys and assessments
.

 

　　The successful launch of the atmospheric environment monitoring satellite will provide important data support for the implementation of "precise pollution control, scientific pollution control, and law-based pollution control", support for in-depth pollution prevention and control, and achieve synergy in pollution reduction and carbon reduction
.
During the "14th Five-Year Plan" period, the Ministry of Ecology and Environment will also lead the development and launch of high-precision greenhouse gas comprehensive detection satellites, and network observations with atmospheric environment monitoring satellites to further improve the global remote sensing monitoring capabilities for major greenhouse gases and atmospheric pollutants.
"Double carbon" strategy, to provide remote sensing monitoring data support to deal with global climate change
