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 ...

Airborne Weather Radar Concept for Measuring Water Surface Backscattering Signature and Sea Wind at Circular Flight [PDF]

, 2016
A concept for measuring water surface backscattering signature and wind over sea using airborne weather radar is discussed. The radar operates in the ground-mapping mode as a scatterometer, in addition to its meteorological and navigation application. An

Inferring Thermodynamic Histories From In Situ Ice Crystal Imagery via Conditional Diffusion Models

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Ice crystal microphysical properties govern cirrus cloud radiative effects, yet their representation in climate models remains inadequate due to insufficient understanding of how thermodynamic histories control crystal morphology. Observational platforms provide only instantaneous snapshots of cloud properties, precluding direct measurement of

Listening to Tsunami Waves Induced by Glacier Calving

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

Characterization and Meteorological Drivers of Dust Events Over California's Central Valley

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Dust events in California's Central Valley pose severe risks to public health, regional air quality, and transportation. Yet, the climatology and meteorological drivers of dust events in the region are poorly characterized due to sparse monitoring and limitations of satellite observations.

Using InSAR Coherence to Map Stand Age in a Boreal Forest

Remote Sensing, 2012
The interferometric coherence parameter γ estimates the degree of correlation between two Synthetic Aperture Radar (SAR) images and can be influenced by vegetation structure. Here, we investigate the use of repeat-pass interferometric coherence &
