Combination of spaceborne synthetic-aperture radar (SAR) images and ad
vanced very-high-resolution radiometer (AVHRR) images is shown to impr
ove quantitative interpretation of the radar imaging mechanisms for th
e ocean surface. This in turn leads to more complete understanding of
complex geophysical processes in the marine environment. We examine tw
o case studies: first, the structure of horizontal roll vortices in th
e atmospheric boundary layer; and second, features of mesoscale coasta
l ocean circulation.
