Abstract

fetched live from OpenAlex

The PROFLAIR (PROSPECT + FLAIR) model was used to invert hyperspectral (EO-1 Hyperion) data using a look up table (LUT) approach to retrieve canopy leaf area index (LAI), leaf chlorophyll content (Ca+b) and canopy integrated chlorophyll content (LAI × Ca+b) of a forest stand impacted by mine tailings pond discharge. The LUT was populated by simulating the model in forward mode using a space of realization generated using a specific distribution of input parameters based on a priori information obtained during a field campaign. Estimated parameters were then compared to field measurements. The results demonstrate a capacity to retrieve canopy LAI and leaf chlorophyll content across the site at accuracies similar to that reported by other wellknown radiative transfer models.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
