While we can measure properties of these upper layers using ground-based instruments, satellite-borne remote sensing instruments can give us a more frequent, global, and often higher spatial resolution perspective. And that is precisely what NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission will deliver.
