A comparative study of nitric oxide (NO) 5.3 micron nighttime emissions in the thermosphere measured by the MIPAS spectrometer and the SABER radiometer satellite instruments has been conducted. The MIPAS and SABER data were inverted to retrieve NO volume emission rates. Spectral fitting of the MIPAS data was used to determine the NO(v = 1) rotational and spin-orbit temperatures, which were found to be in non-local thermodynamic equilibrium (non-LTE) above 110 km. Near 110 km, the rotational and spin-orbit temperatures converged indicating the onset of equilibrium, in agreement with the results of non-LTE modeling. Due to the onset of equilibrium, the NO rotational and spin-orbit temperatures can be used to estimate the kinetic temperature near 110 km, and the results have been compared to NRLMSISE-00 atmospheric model kinetic temperatures. The SABER instrument 5.3 micron band filter cuts off a significant fraction of the NO emission, and therefore modeling of NO is necessary to predict the total band radiance. Correction factors for the SABER filter have been directly determined from the MIPAS data, providing excellent validation of the modeled values used in SABER operational data processing for nighttime conditions. The correction factors were applied to the SABER data to calculate densities of NO(v = 1). A feasibility study was also conducted to investigate the use of NO 5.3 micron emission data to derive NO(v = 0) densities in the thermosphere.
