Diurnal and seasonal albedo trends of wheat at the Bratt's Lake Observatory, Saskatchewan
Bibliographic record
Abstract
The albedo of two wheat fields was measured throughout the 2001 growing season.In response to the maturing crop, the daily albedo increased by approximately 12 percent from seeding to harvest.Before the fields were seeded, the daily albedo was related to the organic litter that remained on the surface from the previous year's harvest; the average daily albedo was 0.173 and 0.161 for the north and south fields respectively.Following cultivation (May 15), the albedo decreased to 0.093 and 0.109 for the north and south fields.The wheat crop emerged on May 27, but the albedo was not solely that of the vegetation until the extended height of the wheat was 0.12 m on June 7.After this date, the albedo increased daily as the wheat crop matured.The albedo reached a plateau (= 0.17) on July 8, and this coincided with the peak of plant fresh weights and the emergence of wheat heads.The albedo began to increase during the

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.
