Abstract
The purpose of this research is to develop a system that can accurately quantify carbon monoxide (CO) concentrations over very small regions in the troposphere by using a gas filter correlation radiometric (GFCR) system and utilizing the Moon as the infrared source. GFCR is an established method of remotely sensing the concentrations of atmospheric gases. The measurement is made by correlating a narrow-band infrared image of the source, taken through a gas filter cell (containing a known pressure of the gas), to an image taken through an evacuated filter cell. Although the GFCR technology was originally developed for use on satellites looking down at the Earth, this study takes the measurement from the Earth looking up at the Moon. An ancillary purpose of this study is to image the surface of the Moon over a narrow wave band (approximately 2102-2183 cm-1) on a large format focal plane array, and to attempt to characterize the surface as an infrared emitter.
