Evaluation of operational lake evaporation methods in a Canadian Shield landscape
Bibliographic record
Abstract
This thesis presents the findings of a study examining the hydrological processes controlling lake evaporation in a Canadian Shield landscape. The purpose of this study is to provide a recommendation on a suitable operational lake evaporation method for implementation in a partially-physically-based meso-scale hydrological model to improve simulation of the climate-hydrological feedback loop. Detailed hydroclimatic observations were recorded for two lakes located in northwestern Ontario, Canada to estimate actual lake evaporation using a Bowen ratio energy balance approach. Multiple operational lake evaporation methods were evaluated for their ability to reproduce the reference lake evaporation rates. Each method was tested for its sensitivity to regionalized and estimated forcing data. The results of this study found a modified version of the Priestley-Taylor combination method most accurately reproduced measured lake evaporation. This method incorporates a novel lumped lake heat storage model developed to estimate heat storage fluxes using re-gional climatic forcing.

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.
