Microwave Emission and Scattering from Ocean Surface Waves in the Southern Beaufort Sea
2014
International Journal of Oceanography
Preserved Fulltext
We evaluate ship-based passive microwave brightness temperatures Tb at 37 and 89 GHz and active polarimetric backscatter at 5.5 GHz (C-band), as these relate to buoy-derived ocean wave parameters for distinct ...
Microwave emission and backscatter are shown to be sensitive to the ocean surface physical roughness as defined by the significant wave height Hm0, compared to wind speed. ...
The roughness can be estimated by active or passive microwave methods of observation. There are a number of satellites for both active and passive microwave observation of sea ice. ...
