One the main key surface parameters involved in the exchange of energy between the atmosphere and oceans are: wind stress, surface turbulent latent and sensible heat fluxes. These are essential to improve modeling simulations of climate variations and oceanic dynamic process studies. Radars and radiometers onboard satellites provide valuable global…
 Several attempts have been made to relate air-sea gas transfer velocities, k, to wind speed, U. Relating k to U is not completely satisfactory because k is known to be driven by sea surface roughness which is not only dependent on wind speed and alternative approaches attempt to relate k…
"Speckle" Wind Speed from ERS-1 SAR imagettes
The European Space Agency ERS-1 C-band VV-polarization instrument ( AMI) offers the unique ability to combine interlaced scatterometer and SAR wave modes. Since a SAR only relies on its platform displacement to achieve fine azimuth resolution, the motion of the surface reduces its nominal resolution. As the wind speed increases,…
