Earth limb emission analysis of Spectral Infrared Rocket Experiment /SPIRE/ data at 2.7 micrometers
Abstract
Atmospheric emission measured at 2.7 microns by the SPIRE earth limb rocket experiment under sunlit conditions has not been fully understood to date. While initial analysis showed this emission to be different from the hydroxyl spectra observed on the night side during the same experiment, the authors were only able to speculate on the processes responsible. In this paper, a model of the fluorescent CO2 hot band emission is developed to explain approximately 40% of the measured SPIRE data. In addition, the results of two other models are included to show the contributions required from CO2 and H2O resonant fluorescence.
