Book Description
An Astrobee D rocket (A30.205-4) was launched at Poker Flat, Alaska, on 9 March 1972 at 1052 hours UT during a condition of Class IBC2 post-breakup auroral display. A near-zenith spectral radiance profile was obtained from 48.5 km to an apogee of 91.9 km on ascent, and from 91.9 km down to about 84.7 km on descent, using a circular variable-filter spectrometer. About 268 spectral scans were obtained during flight, covering the range from 1.4 to 5.0 micrometer at a resolution of about 4 per cent. The dominant emission feature was at 4.3 micrometer, which is attributed to the CO2 nu(3) fundamental. The upward-viewed spectral radiance appeared to range from about 45 MR/micrometer at 48.5 km to less than 2 MR/micrometer at 92 km. A volume-emission-rate/altitude profile for the nu(3) fundamental of CO2 is presented. The profile is based on a simple LTE model and neglects radiation transport. As a result, the model cannot be compared directly with the data. A more complete analysis of the problem is in progress. (Author).

Book Description
A liquid-helium-cooled long-wavelength infrared spectrometer was successfully launched on 22 March 1973 from the Poker Flats Research Facility, Alaska. This spectrometer, which employed a circular variable filter (CVF), was developed over a period of five years and provided the first measurements of the infrared spectrum of the upper atmospheric emissions between 7 and 24 micrometers. The data processing proceeded in a step-by-step manner to provide accurate final data with error limits and an understanding of the spectrometer performance. Each step of the data processing is presented in this report which will provide engineers with information on the spectrometer performance and data analysts with the basis for the final assignment of error limits. Similar procedures can also be used for the data reduction of other CVF flights.
