Abstract:

The information obtained from the two experimental flights was inaccurate in respect to energy measurement and lacked sufficient spectral resolution to show the emission and absorption characteristics of the atmosphere. The lack of data quality was caused by system errors, environmental conditions, launching shock, and interfering signals. These first flights show the changes that would be necessary to obtain useful data with balloon-borne spectrographic equipment. Photometric means of energy measurement in the infrared are extremely difficult to accomplish accurately. Greater precision and ease of measurement will be achieved if this method is discarded in favor of more direct measurement techniques using a fixed temperature comparator. Simplification of the spectrometer will also help to eliminate many problems. Careful attention to the mating of data storage andor telemetry equipment will reduce interfering signals and a program of environmental testing of all equipment will insure more reliable results.
