In this chapter, we focus on the function of “Inform” and the medium “Atmospheric” as shown in Table 1.1 in Chap. 1. This role generally corresponds to global scale long-term monitoring by low Earth orbit (LEO) satellites. Through such observations, influential scientific findings from satellite data have triggered international debates and helped set the agenda for addressing many environmental problems, including stratospheric ozone depletion and global warming. On the other hand, the policy priorities of national
