The visible‐airglow experiment is an airglow photometer designed to measure various thermospheric emission features during the day and night both at low latitudes and in auroras. The photometer has two distinct optical channels, a high‐sensitivity channel with a large field of view and a low‐sensitivity channel with a narrow field of view to resolve small features. The system is protected by a combination attenuator and cathode back‐biasing scheme which allows measurements of maximum sensitivity within a fraction of a second of viewing the sun. This experiment will be a part of the scientific payload on all three Atmosphere Explorer missions.
