Testing the Limits of Surface QG Theory With Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Surface Quasi‐Geostrophic (SQG) theory provides a closed‐form mapping from surface buoyancy to interior stream function under the assumption that interior potential vorticity (PV) vanishes (Q=0) $(Q=0)$. In realistic flows, however, the interior PV is typically nonzero.

Benchmarking Auto‐Regressive Spatio‐Temporal Predictions of Wildfire Spread From the FireBench Simulation Data Set With a Machine Learning Competition

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract As wildfire severity increases, predicting wildfire spread is important for fire and landscape management. However, wildfire spread is a complex phenomenon that is challenging to capture because it depends on many factors, such as wind speed, slope, landscape topography, and fuel properties. Machine Learning (ML) models are powerful tools that

Rapid Physicochemical Screening of Parboiled Rice Using VNIR–SWIR Spectroscopy and Chemometrics

Journal of Food Science, Volume 91, Issue 10, October 2026.
ABSTRACT Efficient quality assessment of parboiled rice is important for industrial processing, but conventional analytical procedures are often time‐consuming, reagent‐intensive, and destructive. This study evaluated VNIR–SWIR spectroscopy combined with chemometric modeling for the rapid prediction of moisture, starch, protein, lipids, fiber, and ash ...

Water Table and Vegetation Shape Peatland CO2 and CH4 Fluxes With Water Table Modulating Temperature Sensitivity

Global Change Biology, Volume 32, Issue 10, October 2026.
Using 14,643 chamber observations from 285 peatland sites, we found that wetter conditions were associated with higher CH4 emissions but lower ecosystem respiration and combined CO2‐equivalent emissions. Apparent CH4 temperature sensitivity also increased with water‐table level, suggesting that fixed Q10 values may misrepresent warming responses ...
