Abstract

fetched live from OpenAlex

Vegetation essential climate variables corresponding to the black-sky albedo (albedo), the fraction of absorbed photosynthetically active radiation (fAPAR), the fraction of canopy cover (fCOVER) and the leaf area index (LAI), as defined by the Global Climate Observing System, are produced for the United Kingdom at 20m resolution on a monthly basis from 2017 to 2023. Maps correspond to variables estimated from input Copernicus Sentinel-2 satellite imagery using the Landscape Evolution and Forecasting (LEAF) Toolbox implementation of the Simplified Level 2 Prototype Processor. The day of retrieval is also provided with each monthly map. Uncertainty estimates are provided based on validation over North America. These products have not been validated over the United Kingdom and are only available for research use.

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.
