Abstract
Abstract. The first three Canadian Arctic ACE valida-tion campaigns were held during polar sunrise at Eureka, Nunavut, Canada (80 ◦ N, 86 ◦ W) from 2004 to 2006 in sup-port of validation of the ACE (Atmospheric Chemistry Ex-periment) satellite mission. Three or four zenith-sky view-ing UV-visible spectrometers have taken part in each of the three campaigns. The differential slant column densities and vertical column densities of ozone and NO2 from these in-struments have been compared following the methods of the UV-visible Working Group of the NDACC (Network for De-tection of Atmospheric Composition Change). The instru-ments are found to partially agree within the required accu-racies for both species, although both the vertical and slant column densities are more scattered than required. This might be expected given the spatial and temporal variabil-

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.
