Abstract : A planned COSPAR publication contains a set of atmospheres for several latitudes and times of year for the altitude region 30 to 80 km developed by G. V. Groves. A second set of atmospheres was developed by W. Priester and I. Harris ('The upper atmosphere in the range from 120 to 800 km,' Proposed CIRA, 1964) for the region between 120 and 800 km for various solar fluxes and times of day. For the purpose of connecting these two sets of atmospheres and also to provide average values of the physical properties, a mean reference atmosphere was prepared as described in this report. The Mean Reference Atmosphere was defined as follows: Between 30 and 80 km the model represents mean conditions throughout the year for latitudes near 30 degrees. Between 120 and 300 km the model represents mean conditions over a 24-hour period for a 10.7-cm wavelength solar flux F of 150 X 10 to the minus 22d power w/sq m/c/s. Between 80 and 120 km a model was developed which provides a smooth connection between the above two parts of the mean atmosphere. (Author)
