Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

open access: yesInternational Journal of Climatology, Volume 46, Issue 9, July 2026.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Coupling UV Camera‐Derived SO2 Emission Rate and Thermal Output at Mount Etna: A Decadal Analysis Across Eruptive Phases

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract At persistently degassing open‐vent volcanoes, SO2 emissions are especially useful to capture the transition from quiescence to eruption, though accurate quantification is challenged by complex volcanic plume dynamics and limited resolution of observations. Here, we present an exceptionally long (∼10–year) record of SO2 emission rates from the

Representation formulas for the moments of the density of zeros of orthogonal polynomial sets

open access: yesLe Matematiche, 1993
The moments of the density of zeros of orthogonal polynomial systems generated by athree-term recurrence relation are represented by Lucas polynomials of the first kind and by Bell polynomials.

Simulation of GIC in the North Island of Aotearoa New Zealand Based on Magnetotelluric Measurements

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract New magnetotelluric (MT) data, combined with older MT data are used to simulate geomagnetically induced currents (GIC) in the power network of the North Island of Aotearoa New Zealand for two geomagnetic storms. For the May 2024 G5 Gannon Storm, simulations use magnetic field data from two separate locations—the Intermagnet geomagnetic ...

Anatomical network analysis of sauropodomorph cranial topology

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract The cranium of sauropodomorph dinosaurs is relatively small and diverse in shape. However, the cranial topology of sauropodomorphs has not previously been investigated. The distinct pattern of physical interactions (joints) among the elements (bones) of an anatomical system (cranium) reveals information about its morphology, leading to a ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

open access: yesThe Photogrammetric Record, Volume 41, Issue 195, July/September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

New Results of Generalized Jacobsthal–Lucas Polynomials with Some Integral Applications

open access: yesMathematics
We study a generalized class of Jacobsthal–Lucas polynomials that depends on two parameters. First, we introduce essential formulas for these polynomials, involving their series representation, inverse formula, and moment formula. These formulas allow us
