The Winds and Currents Mission Concept
The Winds and Currents Mission (WaCM) is a proposed approach to meet the need identified by the NRC Decadal Survey for the simultaneous measurements of ocean vector winds and currents. WaCM features a Ka-band pencil-beam Doppler scatterometer able to map

Polar Sea Ice Detection Using a Rotating Fan Beam Scatterometer
Scatterometers are dedicated to monitoring sea surface wind vectors, but they also provide valuable data for polar applications. As a new type of scatterometer, the rotating fan beam scatterometer delivers a higher diversity of incidence angles and more ...

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.

Assimilation of reprocessed ERS scatterometer data into ECMWF weather analysis on the Mediterranean Sea [PDF]
Since the launch of ERS-1 in 1991 and ERS-2 in 1995, carrying a C-band Scatterometer, a data set of more than thirteen years of backscattered signal from the Earth surface is available for exploitation.

Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Downscaling of Tropical Cyclone Surface Wind Fields With a Hybrid Attention Transformer
Abstract This study employs a Hybrid Attention Transformer‐based super‐resolution model to reconstruct tropical cyclone (TC) surface wind fields. The model downscales coarse‐resolution ERA5 reanalysis data to high‐resolution HWind analyses (1998–2013), increasing the horizontal resolution by a factor of five.

Characterization of ASCAT measurements based on buoy and QuikSCAT wind vector observations [PDF]
The new scatterometer Advanced SCATterometer (ASCAT) onboard MetOp-A satellite provides surface wind speed and direction over global ocean with a spatial resolution of 25 km square over two swaths of 550 km widths.

Abstract Numerical wave models are widely used for wave forecasting and hindcast data set construction; however, their outputs frequently exhibit systematic biases stemming from uncertainties in wind forcing, physical parameterizations, and bathymetry. To address this issue, a deep learning–based bias correction approach is applied to significant wave ...
