Relationships between albedo and microwave emissions over thin newly formed sea ice during fall freeze‐up
Bibliographic record
Abstract
This study examines the relationship between albedo and microwave emissions over thin newly formed Arctic sea ice using in‐situ measurements collected 19 Oct – 13 Nov 2003 in the Cape Bathurst Polynya, southern Beaufort Sea. Regression analysis show that statistically significant relationships exist between the microwave polarization ratio (PR(19)) and sea ice albedo. The albedo derived from the relationship with the PR(19) is compared to the albedo calculated from two parameterization schemes used in the climate models. The results show that the parameterized albedo significantly underestimates over thin ice or overestimates over thick snow‐covered ice relative to both the in‐situ and microwave‐derived albedo. This study suggest that use of satellite passive microwave data should be considered in order to improve the treatment of surface albedo in regional climate models, in seasonal or marginal ice zones.

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.
