Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

open access: yesArchaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

Data Assimilation for a Geological Process Model Using the Ensemble Kalman Filter

open access: yes, 2017
We consider the problem of conditioning a geological process-based computer simulation, which produces basin models by simulating transport and deposition of sediments, to data.

Precipitation‐Buoyancy Relationships in the Life Cycle of Tropical Mesoscale Convective Systems

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study aims to establish process‐level benchmarks linking Mesoscale Convective Systems (MCSs) at various stages of their life cycle to their thermodynamic environment. The relationship between MCS precipitation and an empirical buoyancy measure (BL ${\mathrm{B}}_{L}$) is examined using collocated satellite‐observed MCS tracks and ...

An Optimized Parameterization of Sub‐Grid Scale Advection for Convection Permitting Models

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Convection‐permitting models (CPMs) explicitly resolve deep convection yet under‐resolve the organized lateral exchanges among drafts and their environment that control entrainment/detrainment, precipitation efficiency, and mesoscale structure.

Maintenance of Moisture Anomalies Across Synoptic and Intraseasonal Timescales Over the Indo‐Pacific Warm Pool

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Urban Rainfall Island Detection Remains Uncertain: A Global Sensitivity Analysis Across Data Sets and Methods

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Urbanization can enhance local precipitation through thermodynamic and dynamic effects, yet detection of the urban rainfall island (URI) effect remains uncertain at the global scale because results vary across data sets, methods, and spatiotemporal resolutions.

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

Comprehensive Characterization of Solution‐Cast Polycaprolactone/MXene/Gelatin Composite Films for Biomedical Applications

open access: yesBiopolymers, Volume 117, Issue 3, May 2026.
Polycaprolactone (PCL)/Gelatin/MXene composite films design and evaluation, where blending PCL and natural gelatin (bovine, porcine, and fish) and MXene nanoparticles resulted in coarse morphology, enhanced mechanical strength, and tunable cell‐material interactions, highlighting porcine‐based composite as a promising material for biomedical ...
