Validation of ACE‐FTS stratospheric ozone profiles against Odin/OSIRIS measurements
Bibliographic record
Abstract
Stratospheric ozone profiles measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE‐FTS) have been extensively compared with the coincident ozone profiles measured by the Optical Spectrograph and InfraRed Imager System (OSIRIS) on Odin. All coincidences took place between January 31 and August 5, 2004, with the majority in the Northern Hemisphere. ACE‐OSIRIS statistical comparisons were performed in the altitude range of 16–32 km where OSIRIS ozone data are in a good agreement, 5–7%, with another satellite and ground‐based instruments. At altitudes 3–5 km above and below the ozone peak, ACE‐FTS and OSIRIS profiles agree to within ∼4–7%, while in the vicinity of the peak the ACE‐FTS profiles are systematically lower than OSIRIS profiles by about 10%. This result is consistent for all latitudes between 30°S and 82°N.

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.
