At 2:28 a.m. on May 9, China's first high-resolution atmospheric environment observation satellite, High Score Five, was successfully launched. The three payloads carried by the Anhui Institute of Optics and Mechanics of the Chinese Academy of Sciences will be on track for a long time. The work of pollution prevention and control provided important scientific and technological support and spatial information services to improve the quantification and refinement level of atmospheric remote sensing monitoring in China. This indicates that our country's hyperspectral remote sensing satellite technology has reached the international advanced level.
The three main payloads developed by Anhui Optomechanics are atmospheric trace gas differential absorption spectrometer (EMI), atmospheric major greenhouse gas monitor (GMI), and atmospheric aerosol multi-angle polarization detector (DPC). They are not simple to the earth. Instead of taking 'photographs', the global rapid and accurate information acquisition is carried out for the sensitive components of the Earth's atmosphere, so as to achieve comprehensive detection of the major atmospheric pollution gases, greenhouse gases, clouds, and aerosols.
The atmospheric trace gas differential absorption spectrometer (EMI) is the first high-resolution imaging spectrometer used in the detection of atmospheric trace gases (gases with low atmospheric concentrations, which are markers of environmental pollution). To monitor the air quality over the country and the global air quality, as well as the distribution and transportation of polluting gases. Analyze the effects of human activities and natural emissions on atmospheric composition, air quality, and global climate change. The spectrum has high resolution and a wide spectral range. In-orbit calibration can realize qualitative and quantitative measurement of various trace gases, and finally serve to establish regional and global atmospheric composition monitoring and early warning technology systems in China.
The main atmospheric greenhouse gas monitor (GMI) can obtain periodic hyperspectral survey data, and quantitatively monitor greenhouse gases such as carbon dioxide and methane in the atmosphere. The high-precision absorption spectral information of oxygen, carbon dioxide, and methane can be used to invert the large-scale range. Main atmospheric greenhouse gas concentration data. It can achieve a wide range of scanning observations, fixed-point observations, ocean flare observations, on-board calibration and other work modes.
The atmospheric aerosol multi-angle polarization detector (DPC) can realize the detection of optical and microphysical parameters of global atmospheric aerosols and clouds, provide effective data for the study of global climate change and high-precision atmospheric radiation correction for geo-observation, and at the same time achieve atmospheric fineness. The function of particle pollution monitoring. The load has high-precision, multi-spectral, multi-angle, polarization characteristics of the special aerosol detection capabilities, its spatial resolution is better than the international satellite payload.
Atmospheric trace gas differential absorption spectrometer, atmospheric aerosol multi-angle polarization detector two loads, respectively with 114 ° and 120 ° wide imaging field of view, on-orbit flight for 1 day to obtain global data.
In the future, the three payloads will be synchronously operated on the high-satellite number 5 satellite to meet the needs of China's environmental protection, monitoring, supervision, emergency response, evaluation, planning, and other needs, as well as the needs of climate, environmental change, and mutual relations research. , Three sets of excellent performance, will also greatly enhance China's technical level in the field of atmospheric environmental monitoring.
