Abstract

The model of the infrared glow in the upper polar atmosphere has been developed. An influence of intense auroral disturbances has been investigated. It is shown that infrared emissions play an important role in the thermal state of the upper polar thermosphere. The calculations result in a temperature overestimate about 200 degree(s)K at the altitude 120 km if they were made without infrared cooling. The roles of the major and minor atmospheric components in the thermospheric infrared glow have been studied. It was found that O, NO, CO₂, NO⁺ components are the principal thermospheric infrared radiators. The 63 (mu) , 5.3 (mu) , 15 (mu) and 4.3 (mu) - emissions of these compounds determine the thermospheric thermal state during an aurora. Model calculations of the infrared emission intensities have been compared with rocket measurements in the aurora. A good agreement between model calculations and experimental data has been obtained.
