Abstract

fetched live from OpenAlex

The International Heat Flow Commission global geothermal data set contains over 10,000 borehole temperature logs worldwide. Only about 10% of these data are currently used for climate studies because a number of known nonclimatic energy perturbations are superimposed on the climatic signal. Here we propose a first‐order approach in terms of ground surface temperatures (GSTs) to attempt to correct borehole temperature data for the effects of one of these nonclimatic energy perturbations: deforestation. We simulate the ground surface temperature changes following deforestation using a combined power‐exponential function describing the organic matter decay and recovery of the forest floor after a clear‐cut. Application of this correction could allow many borehole data to be incorporated into the borehole climatology database and, at the same time, may allow land surface models to use geothermal data in regions of known land disruption in order to optimize land surface energy exchange parameterizations.

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.
