Development of a radar simulator for monitoring wake vortices in rainy weather [PDF]
, 2011 A simulator for the evaluation of the radar signature of raindrops within wake vortices is presented. Simulated Doppler spectrum of raindrops within vortices let to think that it could be a potential criterion for identifying wake vortex hazard in ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract In this study, we extend the Cloud Layers Unified by Binormals (CLUBB) turbulence scheme within the GFDL atmospheric model (AM4) by implementing direct momentum‐flux prognosis and a multiscale turbulent lengthscale, to improve the simulation of nocturnal precipitation and associated Low‐Level Jets (LLJs) over the Great Plains (GP). Toward this

An alternative representation of Synthetic Aperture Radar images as an aid to the interpretation of englacial observations [PDF]
The CryosphereGround-penetrating radar reveals subsurface geometry and ice stratigraphy that contains information about past and present dynamics of the cryosphere. Synthetic Aperture Radar (SAR) is a processing technique based on averaging the radar echoes received ...

Introducing Reflected GNSS TEC Data Into ANCHOR Ionospheric Data Assimilation Model
Space Weather, Volume 24, Issue 5, May 2026.Abstract ANCHOR is a novel data assimilation (DA) algorithm developed at the U.S. Naval Research Laboratory to improve ionospheric nowcasting by increasing accuracy and decreasing computational cost. As a parameterized DA model, ANCHOR represents the ionosphere using physical parameters such as the F2 layer peak (Nm $Nm$F2), which characterizes a ...

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Reliability and validity of motion sensor and radar for measuring shuttlecock velocity in badminton
International Journal of Racket Sports ScienceRadar doppler and inertial measurement unit are often used to analyze the projectile velocity. The aim of the present study was to analyse the reliability and validity of a specifically motion sensor (named: Zepp Tennis) and a radar (Doppler-radar gun ...
