Paper Abstract

The purpose of this project is to quantify tropospheric carbon monoxide (CO) concentrations by utilizing a system that applies infrared imaging and gas filter correlation radiometry (GFCR). GFCR offers a differencing method of remote sensing of atmospheric gas concentrations over a large area. A modified, ground-based version for GFCR is used for this project using the moon as our emitting reflected infrared source. The measurement is made by differencing a radiance stream obtained from the moon as passed through an evacuated cell or a cell containing a predetermined concentration of CO. With this measurement, our model is used to correlate this data to real CO concentrations in the troposphere. An ancillary purpose of this project is to calculate the responsivity of the infrared imager used in our measurements by determining the power that is equivalent to the outputted data number.
