30 ans du Protocole de Montréal : retour sur le sauvetage de la couche d'ozone
Bibliographic record
Abstract
Comme tous les ans vers la fin du mois de septembre, le trou d'ozone est revenu. C'est a cette epoque en effet que toutes les conditions sont reunies pour qu'il se reforme au-dessus de l'Antarctique. Durant trois mois (septembre-novembre) les concentrations d'ozone descendent sous les 220 unites Dobson. Pourtant, on n'en parle presque plus de ce trou hautement mediatise. Termines les petits logos Concentration d'ozone (en unites Dobson) mesurees mi-septembre depuis 10 ans par le sondeur infrarouge IASI a bord du satellite Metop. L'amplitude et la repartition geographique du trou (en bleu) varie en fonction des conditions meteorologiques. Anne Boynard/LATMOS, CC BY-NC-ND

How this classification was reachedexpand
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.
