Abstract
Regulatory air dispersion models AUSTAL2000 and CALPUFF are validated by comparing the predicted Ground Level Concentrations (GLC) with the measured dataset resulting from the dispersion of an elevated, buoyant plume release in the Kincaid power plant experiment. Standard statistical measures of the model results are inter-compared. Their performance is scrutinised using scattered, quartile-quartile, and residual plots. The predicted GLC of AUSTAL is twice of Kincaid under turbulent conditions, being less accurate than CALPUFF. The performance of AUSTAL is more consistent with respect to varying atmospheric parameters and distance from stack. The stochastic variability of AUSTAL is also examined.

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 it
