Ten years of Martian nitric oxide nightglow observations
Bibliographic record
Abstract
Abstract We present 10 years of Martian NO nightglow Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars observations in limb and stellar occultation modes. The NO nightglow is used as a tracer of the summer‐to‐winter hemispherical circulation in the upper atmosphere of Mars. Its distribution roughly follows the curve latitude = −80 sin(solar longitude), with deviations. We find that the peak brightness is 5 ± 4.5 kR, situated at 72 ± 10.4 km. It ranges from 0.23 to 18.51 kR and from 42 to 97 km. These values are consistent with previous studies. We also present maps of the brightness of the NO emission peak and its variability, an important factor that can reach up to 50% of the emission and is not reproduced by average brightness model maps. The characteristics and factors that may control the emission are investigated. In particular, we show that the solar activity exerts a positive influence on the number of detections. It does not influence, on the contrary, the brightness or altitude of the peak of the NO nightglow emission. Results presented in this study lead to future comparisons with global Martian atmospheric models and observational targets for the Imaging Ultraviolet Sprectrograph Mars Atmosphere and Volatile Evolution.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
