Sensitivity of GNSS-R spaceborne observations to soil moisture and vegetation [PDF]

, 2016
Global navigation satellite systems-reflectometry (GNSS-R) is an emerging remote sensing technique that makes use of navigation signals as signals of opportunity in a multistatic radar configuration, with as many transmitters as navigation satellites are

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

An enhanced pricing model for truck transportation: a case study in Swedish forestry

International Transactions in Operational Research, Volume 33, Issue 2, Page 775-797, March 2026.
Abstract Determining freight rates for heavy trucks involves a detailed analysis of multiple cost factors, including time, distance, fuel, and other operational costs, which collectively contribute to the overall compensation for transportation services. However, actual remuneration is based on more simplified agreements.

Deep Earthquakes Can Generate Larger Co‐Seismic Displacements Than Shallow Events

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We report the counter‐intuitive observation that a deep earthquake can generate larger co‐seismic displacements than a shallow event across a broad region (e.g., >4° from epicenter). This finding is based on a detailed comparative GNSS analysis of the co‐seismic displacement observations from two MW 8.3 events—the 2013 598.1 km‐deep Okhotsk ...
