Abstract

fetched live from OpenAlex

Systematic air quality measurements were made in the study region of Toronto during the 2015 Pan-Am games (July 14th – July 29th). These measurements were done using the mobile lab CRUISER (Canadian Regional and Urban Investigation System for Environmental Research) to identify emission sources for characterization and emission inventory development. The measurements included several trace gases (NOx, SO2, CO, VOCs, CO2, CH4, and black carbon), air toxics (H2S, aromatics), atmospheric particles, particle composition and meteorological parameters. Additionally, the measurements were systematically designed to cover 18 sub-regions in and around the Greater Toronto Area multiple times so as to cover the different exposure settings such as traffic, industry, residential, commercial, etc. These data aim to provide a good sample of measurements needed for atmospheric air quality model development.

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.

Not 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.
