The CRISTA Experiment on Astro-Spas
Abstract
A Cryogenic Infrared Spectrometer and Telescope for the Atmosphere (CRISTA) to analyze dynamical processes in the middle atmosphere via measurements of the variability of various trace constituents will be flown on a free-flying platform carried into orbit by the Space Shuttle. The CRISTA consists of 3 independent infrared spectrometers and of 3 telescopes simultaneously scanning the atmosphere at the limb in 3 viewing directions, enabling a good horizontal resolution of 400 km x 650 km grid spacing. Vertical resolution is 1.5 km. The spectrometers and telescopes are cooled by supercritical helium.
