12 years of observations of wind and airglow brightness in the northern polar cap mesopause region
Bibliographic record
Abstract
<!--!introduction!--> Observations of wind and airglow brightness in the northern polar cap mesopause region using an all-sky imager (irradiance images) and a field-widened Michelson interferometer (E-Region Wind Interferometer (ERWIN) - wind and irradiance) have taken place at the Polar Environment Atmospheric Research Laboratory (PEARL – Eureka, Nu, 80 N) since 2008. These observations provide insights into solar cycle, seasonal and diurnal variations in airglow brightness and winds. The sodium and oxygen green line airglow brightness correlates strongly with the solar cycle in spite of the observation site being in polar night. The brightness varies strongly during the winter months with several peaks. The cause of this variability is not obvious. The seasonally average meridional winds are generally southward (northward would be expected based on the residual circulation) over the 12 years with maximum southward amplitudes of ~ 10 m/s in the 2014/2016 period. Seasonally averaged zonal winds are generally eastward. The monthly mean zonal winds maximize in January at 10 m/s. The monthly mean meridional winds do not vary strongly during the winter season.

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.
