Calculating a minimum overlap period for successful intercalibration of soil moisture sensors

Vadose Zone Journal
Long‐term in situ soil moisture monitoring inevitably requires sensors to be replaced. Ensuing discontinuities in the data record can be mitigated by intercalibration, however it is unclear how long the existing sensor needs to remain alongside the newly

A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Coastal waters Black Sea geographic intercalibration group: Benthic invertebrate fauna ecological assessment methods

, 2018
The European Water Framework Directive (WFD) requires the national classifications of good ecological status to be harmonised through an intercalibration exercise. In this exercise, significant differences in status classification among Member States are

Cross‐Network Synergies Fundamental to Sustained Global Ocean Carbon Observing

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract The ocean's critical role in absorbing anthropogenic carbon dioxide (CO2) and the resulting changes in the ocean carbon cycle are monitored by global‐scale observing networks, including the Global Ocean Ship‐based Investigations Program (GO‐SHIP), Surface Ocean CO2 Observing Network (SOCONET), and Biogeochemical‐Argo (BGC‐Argo).

Functional Identity Drives Directional Shifts in Freshwater Plankton Biomass–Size Relationships

Ecology Letters, Volume 29, Issue 10, October 2026.
Normalized biomass size spectra (NBSS) for four plankton functional groups across 588 Canadian lakes. Colours correspond to each functional group; points represent the mean normalized biomass for each size bin aggregated across all lakes, ranging from 0.1 to 3.5 μm.
