Numerical modelling of the thermal conditions of the earth's thermosphere.
Abstract
A numerical model of the thermal state of the thermosphere is presented, taking into account infrared radiation in the 1.27-63 micron range (including the vibration-rotation bands of NO, CO2, OH, and O3). The vertical profiles of gas density and temperature determined by the present model agree well with corresponding profiles from the CIRA-72 and Jacchia-77 models. A numerical experiment was used to determine the CO2 (01/0/0) deactivation rate constant in collisions with O at 180-400 K. It is shown that the main energy sink from the thermosphere in the 90-180 km region is determined by infrared radiation in the 15-micron band of CO2 and the 5.3-micron band of NO.
