The Viers Scatterometer Algorithm

, 1996
Various backscatter theories have been investigated in a tank experiment. A simple t.wo-scale model performed better than other more complicated models. In combination with an air-sea interaction module the two-scale model provides the physical basis for the present Viers scatterometer algorithm.

Land data assimilation of satellite‐based surface soil moisture: Impact on atmospheric simulations over the contiguous United States

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
Soil Moisture Active Passive soil moisture retrievals are assimilated into a land surface model and the resulting land reanalysis product is used to initialise the land component of coupled land‐atmosphere experiments. We show that the local impact of land data assimilation on the atmosphere is influenced by two factors: the magnitude by which it ...

THE ADVANCED SCATTEROMETER PROCESSING SYSTEM FOR ERS DATA: THIRTEEN YEARS OF OCEAN WINDS FROM SPACE

Gayana, 2004
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.

Characterization of ASCAT measurements based on buoy and QuikSCAT wind vector observations [PDF]

Ocean Science, 2008
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.

Desert pavements: A hidden key to Earth surface processes

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Desert pavements are a global phenomenon in arid environments, representing one of the most extensive geomorphological and geoecological features on Earth. To a large extent, they determine the interplay of key processes governing current and past landscape dynamics.

Ten Years of SeaWinds on QuikSCAT for Snow Applications

Remote Sensing, 2010
The scatterometer SeaWinds on QuikSCAT provided regular measurements at Ku-band from 1999 to 2009. Although it was designed for ocean applications, it has been frequently used for the assessment of seasonal snowmelt patterns aside from other terrestrial ...

Deep Learning‐Based MultiSource Satellite Data Fusion and Downscaling for Tropical Cyclone Wind Fields

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract High‐resolution observations of ocean surface wind (OSW) are crucial for analyzing and forecasting tropical cyclones; however, current data are insufficient. While data sets such as the Cross‐Calibrated Multiplatform (CCMP) and ERA5 provide gap‐free wind fields, their 25 km resolution and tendency to underestimate cyclone wind speeds limit ...

Impacts of Bogus Vortex Initialization Using Scatterometer-Derived 34 kt Wind Radii and Centers on Tropical Cyclone Forecasts

Remote Sensing
This study demonstrates the positive impact of scatterometer wind-based bogus vortex initialization on forecasts of Typhoon Doksuri (2023). In this scheme, the NCEP analysis vortex in the initial conditions is replaced with a bogus vortex.

Assimilating Advanced Scatterometer Winds in a High-Resolution Limited Area Model Over Northern Europe

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Satellite-based scatterometer ocean surface wind measurements have been shown to improve global weather forecasts through data assimilation. However, these scatterometer data are not yet widely assimilated operationally in high-resolution regional models.

The impact of high rainfall events on the submesoscale salinity field in a coastal sea: Greater Cook Strait, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 4, Page 735-761, December 2025.
ABSTRACT River inflow into the coastal oceanic environment can result in low salinity submesoscale features (LSMFs). The enhanced water column stability sustained within these coherent structures affects local biological productivity. With‐event and seasonal variability of LSMFs were investigated in a coastal sea — Greater Cook Strait — that is ...
