Diverse historical fire disturbance and successional dynamics in Douglas‐fir forests of the western Oregon Cascades, USA

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract We created the first annually resolved records of historical fire occurrence coupled with precise estimates of tree establishment for the northern half of the west slope of the Oregon Cascades, a region that is home to some of the most productive forests on earth.

A multi‐scale assessment of interior Douglas‐fir tree mortality for hazard and risk assessments

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract Land managers use hazard (susceptibility) and risk rating systems to guide the application of forest management treatments that aim to reduce future damages to forests. Rating systems are typically designed for individual damage agents, but tree mortality often results from multiple agents without a clear proximate cause.

Temporal Evolution and Prevention Efficacy of Ritually Induced Fire Ignition Probability in Urban‐Forest Interface Zones: An Empirical Model Based on Forest Fire Risk Data From Kaifu District

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
This study integrates multi‐source geospatial data and fire risk modeling to provide the first quantitative analysis of the dynamic impacts of ritual fires on urban‐forest interface zones. Unlike conventional static risk assessment methods, our proposed temporal evolution model elucidates the coupling mechanisms between anthropogenic activities and ...

AI‐Driven Optimization Techniques for Power Quality Improvement in Microgrids: Trends, Techniques, and Future Directions

open access: yesEnergy Science &Engineering, Volume 14, Issue 1, Page 583-610, January 2026.
Decentralized energy systems are gaining momentum, and microgrids have become a vital component of the modern power landscape. Yet, maintaining power quality within these systems presents ongoing challenges due to the presence of nonlinear loads, variable renewable energy sources, and frequent switching operations.

Photovoltaic Power and Meteorological Datasets With Snow Detection From the Outdoor Solar Power Laboratories of the Finnish Meteorological Institute

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
We describe and publish high‐resolution solar power (PV) output, ancillary, and meteorological data from three high‐latitude sites in Finland during 2015–2021. We performed quality control and daily snow cover classification on the modules based on numerical data and photographs. Snow coverage on PV modules was found to vary significantly based on site
