Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...

Space Weather, Volume 24, Issue 10, October 2026.Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Remote Sensing, 2021 Scatterometers provide very stable ocean vector wind data records. This is because they measure the ratio of backscattered to incident microwave signal over the ocean surface as opposed to an absolute quantity (e.g., emitted microwave signal).

Trends in Aquatic Environmental DNA Research in Alaska
Ecology and Evolution, Volume 16, Issue 7, July 2026.Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...

US East Coast synthetic aperture radar wind atlas for offshore wind energy [PDF]
Wind Energy Science, 2020 We present the first synthetic aperture radar (SAR) offshore wind atlas of the US East Coast from Georgia to the Canadian border. Images from RADARSAT-1, Envisat, and Sentinel-1A/B are processed to wind maps using the geophysical model function (GMF ...

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

Optimization of Airborne Scatterometer NRCS Semicircular Sampling for Sea Wind Retrieval
Remote Sensing, 2023 Airborne scatterometer capability depends on not only the device’s technical characteristics but also the scheme used for surface observations. Typically, a rotating-beam scatterometer uses a circular scheme for sampling normalized radar cross-sections ...
