First simultaneous multistation observations of the polar cap thermospheric winds
Bibliographic record
Abstract
Abstract Based on two northern (Eureka 80.0°N, 85.9°W, magnetic latitude (MLAT) 88, and Resolute 74.7°N, 94.8°W, MLAT 83) and one southern (Jang Bogo 74.7°S, 164.2°E, MLAT 77) polar cap stations, simultaneous thermospheric wind data during the northern (December) and southern (June) winter months were obtained and compared with the National Center for Atmospheric Research Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) simulations driven by the Weimer ion convection model. The TIEGCM simulation overestimates the thermospheric wind by 30 to 60%. The thermospheric winds at Eureka were larger than those at Resolute probably because Eureka is at high‐geomagnetic latitude. The observed ion drifts observed by Resolute Incoherent Scatter Radar North face at Resolute also show that the Weimer ion convection model overestimates the ion drift. The observation and simulation also appear to suggest that the ion convection pattern in the Weimer model may be too large. The observed thermospheric winds at Jang Bogo are smaller than the TIEGCM but mostly in the zonal component. The thermospheric winds are smaller at Jang Bogo than the two northern stations which are likely due to their lower magnetic latitude. The results indicate the presence of internal structure in the thermospheric winds inside the polar cap and call for more observations in the polar cap to be undertaken.

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.
