Welcome to the NASA Pandora project, part of the Pandonia Global Network. This project uses spectroscopy to study ultraviolet (UV) and visible wavelengths of light to determine the composition of the atmosphere and its interactions with Earth’s environment. The Pandora Spectrometer System was designed to specifically look at levels of ozone, nitrogen dioxide and formaldehyde in the atmosphere. What makes the Pandora unique from other ground-based networks at NASA is that it can measure total column profiles, observing different layers of the atmosphere at once.
