Dr. Peter Dalin et al. at the Swedish Institute of Space Physics in Kiruna, Sweden, recently published a peer-reviewed paper titled A novel infrared imager for studies of hydroxyl and oxygen nightglow emissions in the mesopause above northern Scandinavia, in the journal EGU Atmospheric Measurement Techniques.
The novel infrared imager referred to is our Keo Sentry-SWIR. The paper, co-authored by Keo Scientific personnel, describes technical characteristics and presents the first scientific results from this imager as applied to studies of nightglow emissions coming from the hydroxyl and molecular oxygen layers in the mesopause region above Northern Scandinavia.
Validation and comparison of estimated OH(3-1) rotational temperatures with collocated LiDAR and Aura Microwave Limb Sounder satellite temperatures were performed.
