Transport analysis of ozone enhancement in Southern Ontario during BAQS-Met
Bibliographic record
Abstract
Abstract. Twice-daily ozonesondes were launched from Harrow, Ontario (east of Detroit) during the BAQS-Met (Border Air Quality and Meteorology Study) campaign in the summer of 2007. A co-located radar windprofiler measured tropopause height continuously. Simulation results from the dispersion model FLEXPART, using the output of the Environment Canada Global Environmental Multiscale (GEM) weather forecast model, indicate the occurrence of stratospheric ozone intrusion events during the BAQS-Met campaign. This interpretation is supported by the ozonesonde observations, one-minute average surface ozone data measured by the chemistry supersite at Harrow, and geostatistical interpolation results of satellite ozone data that were observed from TES (Tropospheric Emission Spectrometer) onboard NASA's Aura satellite and AIRS (Atmospheric Infrared Sounder) onboard NASA's Aqua satellite. Source-receptor analysis using the GEM-FLEXPART model shows the stratosphere over the Northwest Territories region close to the Beaufort Sea to be the main source of the enhanced ozone at Harrow on 1 July 2007.

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.
