Ozone destruction and production rates between spring and autumn in the Arctic stratosphere
Bibliographic record
Abstract
In situ measurements of radical and long‐lived species were made in the lower Arctic stratosphere (18 to 20 km) between spring and early autumn in 1997. The measurements include O 3 , ClO, OH, HO 2 , NO, NO 2 , N 2 O, CO, and overhead O 3 . A photochemical box model constrained by these and other observations is used to compute the diurnally averaged destruction and production rates of O 3 in this region. The rates show a strong dependence on solar exposure and ambient O 3 . Total destruction rates, which reach 19%/month in summer, reveal the predominant role of NO x and HO x catalytic cycles throughout the period. Production of O 3 is significant only in midsummer air parcels. A comparison of observed O 3 changes with destruction rates and transport effects indicates the predominant role of destruction in spring and an increased role of transport by early autumn.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
