Propagation in longitude and altitude of wave 4 thermospheric perturbations from WINDII data at low and high latitudes
Bibliographic record
Abstract
The diurnal eastward propagating nonmigrating tide of wave number 3 (DE3) has been observed as wave 4 from slowly precessing satellites, for both the ionized and neutral atmospheres. This tide has been identified as arising from deep tropical convection, propagating into the thermosphere and ionosphere, where it has been observed at equatorial latitudes. This feature was previously identified in the Wind Imaging Interferometer (WINDII) O(1S) 557.7 nm emission rate measurements at 250 km in the high‐latitude region as well as the equatorial region. The WINDII wind measurements presented here provide detailed vertical structure from the MLT (Mesosphere and Lower Thermosphere) region to the thermosphere, 100 km to 250 km altitude, the first time that the DE3 winds have been measured over this vertical range. In the present work, the longitudinal propagation of wave 4 at different altitudes is discussed for the daytime and nighttime. The seasonal variations of wave 4 amplitude are compared for different altitudes and latitude regions.

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.
