Abstract

This talk introduces the remote sensing of the earth's atmosphere, land, and ocean by the optically passive observations, focusing on the application of Michelson interferometer and imaging spectrometer, based on the scientific research activities that the speaker participated in at home and abroad.

Michelson interferometer and imaging spectrometer are classic instruments described in physics and chemistry textbooks and courses. They are widely used in laboratory and industry, and also key instruments for the Earth's remote sensing by satellite observations. This talk briefly introduces the basic principles and main results of their satellite observations. For the remote sensing of the Earth's atmosphere, the discussed instruments are the wind imaging Michelson interferometer (WINDII) on the Upper Atmosphere Research Satellite (UARS) for the detection of the wind field in the upper atmosphere. the Michelson interferometer (MIPAS) for passive atmospheric detection on the European Union Environment Satellite (ENVISAT) for the detection of middle and upper atmospheric components, and the Fourier transform spectrometer (FTS) on the Japanese greenhouse gas observation satellite (GOSAT) for near-ground greenhouse gas detection. For the remote sensing of the earth's land and sea, the addressed payloads are the Medium-Resolution Imaging Spectrometer (MODIS) on the Terra and Aqua satellites of the United States Earth Observation System (EOS), and China's Guangmu (广目,Wide Eye) Earth Science Satellite or Global Sustainable Development Goals (SDGs) Series Satellite NO. 1, (SDGSAT-1).

These instruments can conduct global synchronous observation of the earth and obtain a large amount of information: including the atmosphere (temperature, wind, humidity, ozone, water vapor, other atmospheric components, aerosols, clouds and their related properties), land (ground reflectance, surface temperature/radiation, snow/sea ice, land cover and its changes, vegetation characteristics and changes, photosynthesis/primary production, fire), and ocean (backwater radiation/marine aerosol, ocean surface temperature, suspended solids concentration, chlorophyll and primary production). These data can be used for scientific research in physics, chemistry, biology, geography, environmental science and other disciplines; and can also be used for decision-making management by various departments such as industry, agriculture, forestry, water conservancy, meteorology, geology, environmental protection, land resources, planning, aerospace, and national defense and military.

本次演讲介绍了利用光学被动观测技术进行地球大气、陆地和海洋遥感的应用。演讲重点介绍了基于Michelson干涉仪和成像光谱仪的科学研究活动，包括主讲人在国内外参与的相关研究项目。Michelson干涉仪和成像光谱仪是经典的物理和化学教材和课程中的描述。它们被广泛应用于实验室和工业，也是通过卫星观测进行地球遥感的关键仪器。本次演讲简要介绍了它们卫星观测的基本原理和主要结果。对于地球大气的遥感，讨论的仪器包括位于上层大气研究卫星(UARS)上的风成像Michelson干涉仪(WINDII)，用于探测上层大气风场；欧盟环境卫星(ENVISAT)上的Michelson干涉仪(MIPAS)，用于探测中高层大气成分；以及日本温室气体观测卫星(GOSAT)上的傅里叶变换光谱仪(FTS)，用于近地面温室气体探测。对于地球陆地和海洋的遥感，涉及的载荷包括美国地球观测系统(Terra和Aqua卫星)上的中分辨率成像光谱仪(MODIS)，以及中国的广目地球科学卫星和全球可持续发展目标一号卫星(SDGSAT-1)。

这些仪器可以进行全球同步观测，获得大量的信息，包括大气(温度、风、湿度、臭氧、水汽、其他大气成分、气溶胶、云和相关属性)、陆地(地面反射率、表面温度/辐射、雪/海冰、土地覆盖及其变化、植被特征和变化、光合作用/初级生产、火灾)和海洋(返波辐射/海洋气溶胶、海洋表面温度、悬浮固体浓度、叶绿素和初级生产)。这些数据可以用于物理、化学、生物、地理、环境科学和其他学科的科学研究，也可以用于工业、农业、林业、水利、气象、地质、环境保护、土地资源、规划、航空航天、国防和军事等各个部门的决策管理。
