Measurements of odd nitrogen (NOx) at polar latitudes are of crucial importance in understanding the chemical and physical phenomena occurring in the mesosphere and lower thermosphere (MLT) region. The Solar Occultation for Ice Experiment (SOFIE), on board the Aeronomy of Ice in the Mesosphere (AIM) satellite, uses solar occultation measurements at wavelengths of 5.3 and 5.03μm to determine the vertical concentration profiles of NO. The measurements at 5.3μm, especially in the Northern Hemisphere, show an instrumental oscillation due to detector temperature variations that renders the data unusable, without a correction for this effect. This paper describes an empirical correction made to remove this instrumental error. Moreover, a sample of SOFIE NO concentration retrievals with the oscillation removed are analyzed and compared to previous satellite studies of NO to validate the correction.
