Performance Monitoring of Photovoltaic Modules Using Machine‐Learning‐Based Solutions: A Survey of Current Trends

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1663-1682, March 2026.
The graphical abstract presents the concept of applying machine‐learning algorithms to assess the performance of photovoltaic modules. Data from solar panels are fed to surrogates of intelligent models, to assess the following performance metrics: identifying faults, quantifying energy production and trend degradation over time. The combination of data

Ice Spheres as Model Snow: Tumbling, Sintering, and Mechanical Tests

open access: yesFrontiers in Earth Science, 2019
The snow microstructure is crucial for the mechanical behavior of snow, but is usually simplified in numerical models. In Discrete Element Models (DEM), often used in snow mechanics, the microstructure is typically represented by sphere assemblies.

Effective governing equations for poroelastic growing media [PDF]

open access: yes, 2014
A new mathematical model is developed for the macroscopic behaviour of a porous, linear elastic solid, saturated with a slowly flowing incompressible, viscous fluid, with surface accretion of the solid phase.

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 3, March 2026.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Implementation and evaluation of prognostic representations of the optical diameter of snow in the SURFEX/ISBA-Crocus detailed snowpack model [PDF]

open access: yesThe Cryosphere, 2014
In the SURFEX/ISBA-Crocus multi-layer snowpack model, the snow microstructure has up to now been characterised by the grain size and by semi-empirical shape variables which cannot be measured easily in the field or linked to other relevant snow ...

Processes Driving Drift‐Ice Evolution and Its Interaction With the Oceanic and Atmospheric Boundary Layers

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Sea ice is a crucial component of polar climate systems and is undergoing substantial changes in both hemispheres due to evolving climatic conditions. Arctic sea ice is transitioning from perennial to seasonal cover, and the Southern Ocean sea ice is exhibiting recent minima and enhanced seasonality.

Snow mechanics: from snow microstructure to avalanche formation

open access: yes, 2022
Snow is a fascinating material. Its composition is relatively simple, mainly air and ice, but the arrangement of these components in three dimensions is extremely diverse. This diversity of microstructure, often reduced to discrete snow types, originates from different snowflake growth mechanisms in the atmosphere and the continuous evolution of snow ...

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...
