Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Comparative Analysis of the Performances of a Nonlinear Observer and Nonlinear Kalman Filters in the Presence of Non‐Gaussian Disturbances

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 7, Page 3896-3913, 10 May 2026.
ABSTRACT This paper focuses on state estimation for a fairly general class of systems, involving nonlinear functions and disturbances in both the process dynamics and output equations. A nonlinear observer that satisfies a H∞$$ {\boldsymbol{H}}_{\boldsymbol{\infty}} $$ disturbance attenuation constraint in addition to providing asymptotic stability in ...

Wildfire smoke reduces water temperature and metabolic rates in lakes and ponds across a small headwater watershed

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Pervasive smoke from wildfires can alter fundamental aspects of lake ecosystems, such as water temperature and rates of gross primary production and ecosystem respiration (ecosystem metabolism). However, understanding the effects of smoke on lake temperature and metabolism remains challenging, due to spatiotemporal variability in smoke cover ...
