Measurements of O<sub>3</sub>, NO<sub>2</sub> and Temperature during the 2004 Canadian Arctic ACE Validation Campaign
Bibliographic record
Abstract
The 2004 Canadian Arctic ACE Validation Campaign was conducted to provide correlative data for validating measurements from the Atmospheric Chemistry Experiment (ACE) satellite mission. These measurements were made at Eureka, Nunavut during polar springtime 2004. Six ground‐based instruments were operated during the intensive phase of the campaign and ozonesondes and radiosondes were flown. During this time, ACE‐FTS and ACE‐MAESTRO were performing solar‐occultation measurements over the Canadian Arctic. We report the first comparisons between campaign measurements and those from ACE, focusing on O 3 , NO 2 and temperature. Initial mean O 3 profiles from ACE‐FTS and ACE‐MAESTRO agree to within 20% between 10 and 30 km, and the NO 2 profiles agree to within 40% between 17 and 40 km, which is within the standard deviations. The ACE‐FTS temperature profiles agree to better than 2.5 K with the radiosonde temperatures from 10 to 32 km and with the lidar temperatures from 17 to 45 km.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
