Adaptive Thresholding in Marine RADARs

Iranian Journal of Electrical and Electronic Engineering, 2010
In order to detect targets upon sea surface or near it, marine radars should be capable of distinguishing signals of target reflections from the sea clutter. Our proposed method in this paper relates to detection of dissimilar marine targets in an inhomogeneous environment with clutter and non-stationary noises, and is based on adaptive thresholding ...

Morphological Characteristics of Tropical Precipitation Features Producing Extreme Instantaneous Rain Rates in GPM and DYAMOND Global Storm Resolving Models

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The influence of the spatial organization of tropical convection on the production of extreme instantaneous localized tropical rain rates remains poorly constrained, both in observations and in models. Using retrievals from the Ku‐band radar onboard the GPM satellite, we identify tropical precipitation features (PFs) and quantify their ...

A Hybrid Superdroplet–Bin Microphysics Approach Reveals How Large Salt Particles Trigger Rain in Non‐Precipitating Warm Convective Clouds

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract This study develops a Superdroplet‐Bin hybrid microphysics scheme within the Weather Research and Forecasting (WRF) model to investigate hygroscopic seeding of warm convective clouds. The Super‐droplet method describes 3D transport, deliquescence, condensation, and collision‐coalescence growth of seeding agents or solution droplets, while the ...

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...

Surface‐Constrained Reconstruction of Spatiotemporal Turbulence Dissipation in the Convective Boundary Layer Using Physics‐Guided Machine Learning

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Turbulence dissipation rate (EDR) governs the conversion of turbulent kinetic energy to heat and thereby controls vertical mixing, transport, and energy exchange in the convective boundary layer (CBL). The spatiotemporal structure of EDR remains poorly constrained, as observations are limited to point measurements or sparse vertical profiles ...

Climatology of Atmospheric Boundary Layer Height Over Nearshore and Open Ocean Regions of the Western North Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric boundary layer height (ABLH) plays an important role in air–sea interactions and regional climate over the western North Pacific (WNP). Using ERA5 reanalysis data from 1979 to 2025, this paper investigates the interannual variability, monthly variations, and seasonal spatial patterns of ABLH.

The Influence of Sea‐Land Breeze on the Circulation and Air‐Sea Thermodynamics of the Mississippi Sound and Bight

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract High spatial and temporal resolution wind forcing is essential to capture the highly variable atmospheric circulation driving ocean currents in shallow waters and across complex coastal features in the Mississippi Sound. In this study, we examine the sensitivity of modeled hydrodynamics to sea‐land breeze (SLB) circulation. Two versions of the

How Well Can the Surface Water and Ocean Topography (SWOT) Satellite Mission Observe Irrigation Canals?

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The capability of the Surface Water and Ocean Topography (SWOT) satellite for observing irrigation canals has remained relatively unexplored. Here, we assess SWOT observability of irrigation canal networks across 22 Asian countries using a new confidence level (CL) metric.

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.
