Abstract

fetched live from OpenAlex

В феврале 2022 г. разрушение озона развивалось по сценарию, близкому к озоновой аномалии 2020 г. Отношение смеси озона падало на 61% от многолетней (2006-2019 гг.) нормы 14 марта 2022 г. против 96% 27 марта 2020 г. на высоте 20 км в Эврике, Канада. В то же время, отношение смеси ClO росло до 1.1 млрд-1 18 февраля 2022 г. против 1.2 млрд-1 16 марта 2020 г. на высоте 21 км. Позже, 20 марта 2022 г., произошло мажорное потепление, в результате температура в стратосфере поднялась на 20-25 K во всех исследованных пунктах: Эврика, Канада; Ню-Олесунн, Норвегия; Резольют, Канада; Туле, Гренландия. Высокая корреляция колебаний указанных параметров на приблизительно одинаковых высотах их регистрации, а также между общим содержанием O3 and ClO, рассчитанным из профилей указанных параметров, указывает на их тесную взаимосвязь. In February 2022, ozone depletion developed according to a scenario close to the ozone anomaly of 2020. The ozone mixture ratio fell by 61% of the long-term (2006-2019) norm on March 14, 2022, against 96% on March 27, 2020 at an altitude of 20 km in Eureka, Canada. At the same time, the ratio of the ClO mixture increased to 1.1 billion-1 on February 18, 2022 against 1.2 billion-1 on March 16, 2020 at an altitude of 21 km. Later, on March 20, 2022, major warming occurred, as a result, the temperature in the stratosphere rose by 20-25 K in all the studied points: Eureka, Canada; Nu-Alesund, Norway; Resolute, Canada; Thule, Greenland. The high correlation of the fluctuations of these parameters at approximately the same heights of their registration, as well as between the total content of O3 and ClO calculated from the profiles of these parameters, indicates their close relation.

Not 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.
