Abstract
Abstract The development of the new process‐based TRIPLEX‐GHG model derives from the Integrated Biosphere Simulator (IBIS), which couples nitrification and denitrification processes to quantify nitrous oxide (N 2 O) emissions from natural forests and grasslands. Sensitivity analysis indicates that the nitrification rate coefficient (COE NR ) is the most sensitive parameter to simulate N 2 O emissions. Accordingly, we calibrated this parameter using data from 29 global forest sites (across different latitudes) and grassland sites. The average nitrification rate coefficient gradually increases in the order of tropical forest to grassland to temperate forest to boreal forest, and giving means of 0.009, 0.03, 0.04, and 0.09, respectively. This study validated the mean value for each ecosystem at 52 sites globally. Calibration results both indicate the good performance of the model and its suitability in capturing seasonal variation and magnitude of N 2 O flux; however, it is limited in modeling N 2 O uptake and increments during periods of snowmelt. Additionally, validation results indicate that simulated and observed annual or seasonal N 2 O fluxes are highly correlated (R 2 = 0.75; P < 0.01). Consequently, our results suggest that the model is suitable in simulating N 2 O emissions from different forest and grassland land types under varying environmental conditions on a global scale.

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
