Abstract
A novel ceilometer validation is presented for a nocturnal elevated PM layer observed over Vancouver, British Columbia. The boundary-layer structure was confirmed by both meteorological and PM vertical profiles. This result is especially significant due to the low PM concentrations present during the observational period (a mean PM10 concentration of 10.6 μg m−3 was recorded) and suggests that ceilometers are able to resolve boundary-layer structure more subtle than that normally present during periods of poor air-quality. A direct relation between backscatter intensity and PM concentration suggests that not only may these relatively cheap, robust ceilometers be used to elucidate boundary-layer structure, but they represent a promising quantitative alternative to the measurement of PM concentrations that complements existing surface-based instrumentation. This study extends and confirms the growing body of evidence supporting the utility of ceilometers for making detailed, cost-effective measurements of the boundary-layer.

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
