摘要
Although Earth’s surface parameters obtained from satellite data have become more and more precise,it is still difficult to guarantee temporal consistency and spatial continuity for large-scale geoscience phenomena.Developing new Earth observation platforms is a feasible way to improve the consistency and continuity of such data.As the planet’s only natural satellite,the Moon has special advantages as a platform for observing Earth,including long lifetime,whole disk view,tectonic stability and unique perspective.After presenting the observation geometry constructed by using the ephemeris,this paper mainly discusses the characteristics of a lunar platform and the proper Moon-based sensors,as well as the scientific objectives of Moon-based Earth observation.Solid Earth dynamics,the energy budget of Earth,Earth’s environmental elements and the Earth-space environment are four potential applications analysed in this paper.
