Abstract
S1. Filter samplingIn total, 245 PM10 filters from Magadino (Jan '13 -Sep '14) and Zurich (Jan -Dec '13), and 65 PM2.5 filters from Magadino (Jan -Sep '14), were collected over 24 h every 4 th day, with a total sampled air volume of 720 m 3 per filter.Zurich-Kaserne is an urban background site, located in a courtyard in the city center of Zurich (410 m.a.s.l.).The location is surrounded by roads with rather low traffic and is not affected by major emissions from industries.Magadino-Cadenazzo is a rural background air quality monitoring station located in Southern Switzerland, south of the Alps in the Magadino plane close to the Lago Maggiore, about two kilometers outside the small village of Cadenazzo.The site is surrounded by agricultural land and forests and is exposed to wood smoke from residential heating during winter.Biomass burning at both sites might be associated with domestic heating during wintertime and with open fires, agricultural waste disposal, waste burning etc., during the other seasons.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
