A comparison of CADI‐inferred <i>F</i> region plasma convection and DMSP ion drift above Resolute Bay
Bibliographic record
Abstract
CADI ionosonde estimates of the F region plasma convection over Resolute Bay (NWT, Canada, MLAT = 83.5°) are compared with nearly simultaneous ion drift measurements on board DMSP satellites passing in the vicinity of the station. First, CADI vectors are projected onto the cross‐track directions of DMSPs for 141 events and compared with ion drifts measured by DMSPs in these directions. The best linear fit line is found to have a slope of 0.75 and a shift of −13 m/s indicating good correspondence between the instruments with CADI showing minor underestimation. Then, a fully two‐dimensional comparison is performed by considering (1) magnitudes and azimuths and (2) eastward and northward components of the CADI and DMSP vectors. Reasonable agreement is shown as well. For both comparisons, the data spread is small; the correlation coefficients are of the order of 0.7–0.8. The strongest differences between the instruments were found to occur for the periods with spotty enhancement of the plasma flow detected by one or both instruments.

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.
