In January and August 1968 a series of rocket release experiments for upper atmosphere structure were performed. These experiments involve density profile and wind profile measurements and also measurements of atomic oxygen, both the neutral density profile and the emission profile of the oxygen line OI5577. The experiments consisted of chemical releases of nitrogen oxide NO and Trimetyl Aluminium TMA. The TMA release during twilight gave spectra of the A squared sigma minus X squared sigma transition of molecular A10. These spectra were taken from different altitudes and when analyzed, gave temperature profile of the thermosphere. Measured temperature profiles from these experiments were compared with the COSPAR International Reference Atmosphere of 1965 CIRA 1965 and also compared with the US Standard Atmosphere Supplement of 1966.
