Analysis of 4.3 Micrometer ICE CAP Data.
Abstract
This report describes the theoretical analysis of infrared radiance data at 4.3 micrometer which was obtained from auroral rocket shots from Poker Flat, Alaska in 1972 and 1973 as part of the ICE CAP program. It is shown that the radiance in this wavelength region cannot be accounted for by NO+ emission, but that all of the data is well described by CO2 emission at 4.3 micrometer where the CO2 is excited via vibrational energy transfer from aurorally produced vibrationally excited molecular nitrogen. The spatial and temporal characteristics of the 4.3 micrometer emission have been accounted for. The theory considers the time dependence of the formation of vibrationally excited nitrogen and new theoretical work concerning the residence time of vibrationally excited nitrogen at various altitudes is presented.
