IS23B:
Sea Surface Roughness Observed by High-Resolution Radar I


Session ID#: 37233

Session Description:
Changes in the sea surface roughness are usually associated with a change in the sea surface wind field. This interaction has been exploited to measure the sea surface wind speed by scatterometry. A number of features on the sea surface associated with change in roughness can be observed on synthetic aperture radar (SAR), because of the change in Bragg backscatter of the radar signal by damping of the resonant ocean capillary waves. The change in sea surface roughness can also be observed in the sun glint area of optical imagery. With various radar frequencies, resolutions, and modes of polarization, sea surface features have been analyzed in several campaigns, bringing very different datasets together thus allowing for new insight in small scale processes at a larger areal coverage. This session aims at investigating sea surface features including but not limited to: upwelling, oceanic fronts, coastal processes on reefs, lee waves, swell, wind shadows, wind rolls, internal structures of hurricanes, oil seepage and natural slicks, internal waves, and turbulent effects due to wakes. Studies on turbulent features at the air-sea interface at a resolution below 10 m using a combination of remote sensing, in situ and modeling techniques are encouraged.
