Spatial Heterogeneity and Inhomogeneity of Cirrus Microphysical Properties on Kilometer Spatial Scales

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Previous studies reporting the spatial inhomogeneity and heterogeneity of cirrus cloud properties have primarily been case studies derived from relatively small data sets. This study evaluates the spatial heterogeneity and inhomogeneity of cirrus bulk microphysical properties using ∼60 hr of in situ measurements from eight field campaigns. The

The 2025 Mw 7.6 Aomori‐Oki Megathrust Sequence and a Slip‐Parallel Seismic Belt to the Trench

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The 2025 Mw 7.6 Aomori‐Oki earthquake nucleated near the 1968 Mw 8.3 Tokachi‐Oki rupture area. Our waveform inversion reveals large slip (>1 m) extending ∼40 km northward from the hypocenter, overlapping the inferred 1968 northern asperity. Minor secondary slip (0.2–0.6 m) was resolved ∼60 km updip, and high‐precision relocations show that ...

The Global Contribution of Individual Submarine Groundwater Discharge Components to the Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Saline submarine groundwater discharge (SSGD) contributes to ocean chemistry through water‐rock interactions as seawater circulates in coastal aquifers. Its components, driven by different mechanisms, exhibit varying residence times and degrees of chemical alteration, so constraining solute fluxes requires quantifying each component.

Listening to Bryde's Whales With an Island Seismometer: Low‐Frequency Call Detection and Seasonal Patterns Revealed by Deep Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Bryde's whales form a major coastal aggregation in the Beibu Gulf, China. Using 1 year of continuous island‐based seismic recordings from Xieyang Island, we established a large labeled data set of coastal Bryde's whale calls with more than 1.7 million samples.

Approximate solution of hyperbolic conservation laws by discrete mollification

Applied Numerical Mathematics, 2009
The authors propose explicit schemes for one-dimensional linear and nonlinear hyperbolic conservation laws. Combination of these methods with discrete mollification yields new methods with the following properties: Large time steps are allowed and stability is preserved.

A numerical scheme based on discrete mollification method using Bernstein basis polynomials for solving the inverse one-dimensional Stefan problem

Inverse Problems in Science and Engineering, 2020
This paper concerns a one-phase inverse Stefan problem in one-dimensional space. The problem is ill-posed in the sense that the solution does not depend continuously on the data.

Regularization of a nonlinear inverse problem by discrete mollification method

2021
Summary: In this article, the application of discrete mollification as a regularization procedure for solving a nonlinear inverse problem in one dimensional space is considered. Illposedness is identified as one of the main characteristics of inverse problems. It is clear that if we have a noisy data, the inverse problem becomes unstable.
