description | The vibrational distribution of nitric oxide
in the polar ionosphere computed according to the one-dimensional non-steady
model of chemical and vibrational kinetics of the upper atmosphere has been
compared with experimental data from rocket measurement. Some input parameters
of the model have been varied to obtain the least-averaged deviation of the
calculated population from experimental one. It is shown that the least
deviation of our calculations from experimental measurements depends
sufficiently on both the surprisal parameter of the production reaction of
metastable atomic nitrogen with molecular oxygen and the profile of atomic
oxygen concentration. The best agreement with the MSIS-83 profile was obtained
for the value of surprisal parameter corresponding to recent laboratory
estimations. The measured depression of level <i>v</i>=2 is obtained in the
calculation that uses sufficiently increased concentrations of atomic oxygen. It
is pointed out that similar measurements of infrared radiation intensities could
be used to estimate the atomic oxygen concentrations during auroral disturbances
of the upper atmosphere.<br><br><b>Keywords.</b> Atmospheric composition and structure
