摘要

Thermospheric nitric oxide (NO) has a strong response to the energy injection, and it serves as the "natural thermostat." Previous studies have tended to concentrate on NO radiative flux and its effectiveness on the global energy budget rather than the altitudinal dependence. In this study, measurements from TIMED/SABER (the Sounding of the Atmosphere using Broadband Emission Radiometry instrument on TIMED satellite) were used to investigate the variation of the NO radiance cooling in thermosphere as a function of altitude, latitude, and local time. Using the methods of principal component analysis and spherical harmonic regression, we have developed an empirical model to capture the most significant variation in NO radiance cooling for the altitude range 100–280 km. The model reproduced the variations of NO radiation at different latitudes and altitudes. Moreover, the integrated model NO radiative flux is in good agreement with satellite measurements with a correlation coefficient up to 0.96. This empirical model can be used to investigate the NO cooling evolution and serve as a validation tool for future physics-based simulations.
