An Improved Semi-Empirical Model for Radar Backscattering from Rough Sea Surfaces at X-Band [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2018 We propose an improved semi-empirical scattering model for X-band radar backscattering from rough sea surfaces. This new model has a wider validity range of wind speeds than does the existing semi-empirical sea spectrum (SESS) model.

Surface roughness of Titan's hydrocarbon seas
Earth and Planetary Science Letters, 2017 Abstract We derive fields of solutions for the surface properties (roughness and permittivity) of the liquid hydrocarbon bodies Ligeia, Kraken and Punga Mare on Titan by applying the Radar Statistical Reconnaissance (RSR) technique to the Cassini RADAR observations in altimeter mode during the northern early summer. At the time of observation, Kraken

Arctic Sea Ice Surface Roughness Estimated from Multi-Angular Reflectance Satellite Imagery
Remote Sensing, 2018 Sea ice surface roughness affects ice-atmosphere interactions, serves as an indicator of ice age, shows patterns of ice convergence and divergence, affects the spatial extent of summer meltponds, and affects ice albedo.

Remote Sensing, 2017 The Arctic sea ice cover has decreased strongly in extent, thickness, volume and age in recent decades. The melt season presents a significant challenge for sea ice forecasting due to uncertainty associated with the role of surface melt ponds in ice ...

Detection of the 2010 Chilean tsunami using satellite altimetry [PDF]
Natural Hazards and Earth System Sciences, 2011 Tsunamis are difficult to detect and measure in the open ocean because the wave amplitude is much smaller than it is closer to shore. An effective early warning system, however, must be able to observe an impending tsunami threat far away from the shore ...

Atmospheric Science Letters, 2022 The modeling of the atmospheric boundary layer over sea ice is still challenging because of the complex interaction between clouds, radiation and turbulence over the often inhomogeneous sea ice cover.

Canadian Journal of Remote Sensing, 2019 Utilizing synthetic aperture radar (SAR) data to understand and map sea ice roughness is an active area of research. An object-based image analysis is here used to quantitatively link the winter first-year sea ice surface roughness to C-band RADARSAT-2 ...

The role of atmospheric boundary layer-surface interactions on the development of coastal fronts [PDF]
Annales Geophysicae, 2007 Frictional convergence and thermal difference between land and sea surface are the two surface conditions that govern the intensity and evolution of a coastal front.

Determining Variability in Arctic Sea Ice Pressure Ridge Topography With ICESat‐2
Geophysical Research Letters, 2022 We investigate the characteristics and distribution of pressure ridges in Arctic sea ice using a novel algorithm applied to ICESat‐2 surface heights. We derive the frequency and height of individual pressure ridges and map surface roughness and ridging ...

Influence of Wave State and Sea Spray on the Roughness Length: Feedback on Medicanes
Atmosphere, 2018 Occasionally, storms that share many features with tropical cyclones, including the presence of a quasi-circular “eye” a warm core and strong winds, are observed in the Mediterranean.
