Coverage analysis on Global change sensitive regions from moon based observation

Abstract

Global change refers to changes in earth system function at a global scale including atmospheric and ocean circulation, hydrologic and biogeochemical cycles, and changes in resource, land use and others. Global change is characterized by its large scale and needing long-term observation. Moon is an ideal platform for observing global change. In order to reveal its potentials for observing of global change sensitive regions, this paper focuses on the coverage analysis of moon-based earth observation which makes use of the JPL ephemeris and generates observation Boolean matrixes of global change sensitive regions. The result shows that the moon based earth observation has advantages in wide swath, continuous observation and large effective coverage which contribute to the monitoring and understanding of global change.
