Abstract
Evaporation (ET) from land surfaces in high latitudes is examined on a circumpolar perspective based upon the study results obtained in various environments, from boreal forest (taiga) to the high Arctic desert. Direct and indirect methods of evaporation measurement are reviewed, as well as numerous computational techniques. We have focused upon methods conveniently adopted for calculating evaporation when detailed information on meteorological conditions within the surface boundary layer is not available. These methods range from complicated ones, such as eddy correlation, energy balance and Penman equations, to empirical relationships between ET and incoming solar radiation. Great attention was paid to the principles of each method, especially those developed in Russia as they differ from most of the methods utilized internationally. For example, the Budyko–Zubenok empirical scheme is based upon the principle of potential evaporation, which is affected by soil moisture (SM). This relationship between ET and SM, expressed in terms of the field capacity, has been found to be non-linear; a complication that is not typically accounted for in traditional approaches. This paper also contains a brief review of a number of evaporation case studies including Alaska (USA), north-western Russia and Siberian taiga, Yukon basin (Canada), mountainous forest on Hokkaido Island (Japan), Canadian Arctic and glacierized basins of Greenland.

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 it
