Abstract
Optical remote sensing of emission lines is a well-established approach to estimating atmospheric parameters. The neutral oxygen 844.6 nm emission line has long been considered a good candidate for estimating the oxygen density in the upper thermosphere due to its brightness and relatively simple photochemistry. The primary challenge is that oxygen density estimation requires knowledge of the absolute brightness of the emission line. This thesis presents the design, operation, and analysis of the Sky-Calibrated Imaging Photometer (SCIP). SCIP is a new ground-based instrument with the novel capability of absolute brightness calibration using astronomical sources. The derivation of the emission line brightness from a two-channel photometer is presented, followed by the design of the autonomous instrument and environmental chamber, analysis of detector noise, and signal-to-noise ratio prediction.
