Abstract

fetched live from OpenAlex

In order to provide some useful data for the studies of the radiative and chemical processes in stratosphere,the variation trends of the trace gases(O3,HCl,HF,NO NO2,H2O and CH4) in stratosphere have been analyzed for various altitudes and latitudes by using the HALOE data from 1992 to 2005.The results show that the trends of the traces gases are different in various latitudes as well as in various levels of stratosphere.Comparing the trends of O3 with the trends of the other traces gases shows that the recovery of the ozone concentration after the mid-1990s is clear in the upper stratosphere,and the trend of O3 in these 14 years is opposite to the trend of HCl,HF and water vapor.In the middle stratosphere,the variation of O3 is complicated.Besides destroyed by the ozone-depleting substances,ozone concentration would be affected by the other factors.The increase trends of ozone mixing ratio from 1997 to 2002 was opposite to the decrease trends of HCl,NO,NO2 and water vapor.That means the benefits of Montreal agreement which make the decrease of those traces,have won initial success for the recovery of the ozone concentration not only in upper stratosphere but also in middle stratosphere.

Full frame distilled prediction

Teacher imitation

Not 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.
