Abstract

fetched live from OpenAlex

The climatological ozone profile in the tropics is shaped like an “S,” with a minimum at the surface, a maximum at 330 K (∼6.5 km), another minimum at 345 K (∼11.2 km), and a subsequent increase toward the tropopause. These features can be reproduced by a very simple model whose only free parameter is the mean ozone mixing ratio of air detraining from deep convective clouds. To first order, the climatological ozone profile in the tropics arises from a balance between vertical advection, deep convection, and chemistry. The 345 K ozone minimum is coincident with a lapse rate minimum. Both minima are associated with a large increase in convective outflow at 345 K followed by a quasi‐exponential decrease. The increase in ozone above 345 K is caused mainly by decreased injection of low‐ozone air from the boundary layer. The model tends to underestimate ozone between 340 and 365 K (∼9–15 km). This is most likely due either to an underestimate by the model of in situ ozone production or to eddy transport of ozone from the lowermost stratosphere into the upper tropical troposphere across the subtropical jet. The magnitudes of both these processes are poorly constrained by measurements. In the case of ozone production this is mainly due to a lack of measurements of HO x precursors such as acetone and CH 3 OOH between 11 and 16 km.

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.
