The NOAA FM-CW Snow-Level Radar

open access: yesJournal of Atmospheric and Oceanic Technology, 2017
AbstractA vertically pointing radar for monitoring radar brightband height (BBH) has been developed. This new radar utilizes frequency-modulated continuous wave (FM-CW) techniques to provide high-resolution data at a fraction of the cost of comparable pulsed radars.

Taxonomy of IMT Interference on Aeronautical Systems

open access: yesRadio Science, Volume 61, Issue 4, April 2026.
Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...

Near‐Inertial Wave Trapping Inside a Fine‐Scale Anticyclonic Eddy During the BioSWOT‐Med 2023 Cruise: Turbulence and Energy Flux

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,

Forecasting Equatorial Plasma Bubbles From Precursor TEC Signatures Observed by C/NOFS

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract This study investigates the potential of localized total electron content (TEC) perturbation measurements, possibly associated with bottomside upwelling of the F‐layer, as precursors for forecasting ionospheric plasma irregularities, particularly the equatorial plasma bubbles (EPBs).
