Dependence of ozone lamina characteristics on the distance from the polar vortex edge – possible relation to climate change
Bibliographic record
Abstract
Ozone laminae are narrow layers of enhanced (positive) or depleted (negative) ozone concentration. Large laminae are formed at the vicinity of polar vortex and they are one of the mechanism of air masses exchange between the polar vortex and its surrounding. We observed similar long-term trend pattern in the total amount of ozone in laminae per profile and in the number of laminae per profile as in the case of total ozone (Krizan and Lastovicka, JGR, 2005). The aim of this poster is to find the dependence of the ozone lamina characteristics on the value of potential vorticity at the pressure levels in the stratosphere. We expect the ozone laminae will be more frequent near the vortex edge. The number of ozone laminae will decrease with increasing distance from the vortex edge. We use data from the European middle latitudes ozonosonde stations taken from WOUDC database in Toronto. We use data from 3 stations: Hoheinpeisenberg, Edmonton and Resolute Bay. Possible changes with time of the dependence of ozone lamina characteristics on the the distance from the polar vortex edge as a consequence of long-term changes of ozone and greenhouse gas concentration in the lower stratosphere will be searched for.

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.
