Initial validation comparisons for the Atmospheric Chemistry Experiment (ACE‐FTS)
Bibliographic record
Abstract
The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE‐FTS) is the primary instrument for the ACE satellite mission. The initial validation of ozone profiles from ACE‐FTS is based on comparisons with profiles from satellite‐borne instruments and balloon‐borne ozonesondes. The satellite instruments include the SAGE III and POAM III instruments. The ACE profiles were recorded during March 2004 at high latitudes in the northern hemisphere (>65°N) and were processed with the version 1.0 retrieval algorithm. The ACE‐FTS results were found to agree within 10% with those from the other satellite measurements between 15 and 40 km, with ACE‐FTS measuring less ozone near the profile maximum. The ACE‐FTS has a lower vertical resolution than SAGE III or POAM III and this may contribute to the observed discrepancy. The comparisons with ozonesonde measurements suggest that the ACE‐FTS accurately captures vertical structures in the ozone profile that are on the order of several kilometers thick.

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; both teacher heads agree on what is shown here.
