AMI-SAR has two modes of operation: (2D spectra of ocean surface waves) and image (high resolution 2D all-weather images of ocean, ice mode and land surfaces) planned by AMI/WS Wind scatterometer in C-Band. WSCAT obtains 5.3 GHz --- end July information on wind speed and direction at the sea 2011 surface. Altimeter RA Single frequency radar altimeter in Ku Band. 13.8 GHz --- pointing sensor that measures wind speed, significant wave height, sea surface elevation, ice profile, land and ice topography, and sea ice boundaries. Operational SAR ASAR Advanced SAR in C band. It ensures continuity with 5.331 GHz See section (2002-) ERS-2 AMI/SAR 4.7.2 Altimeter RA-2 13.575 GHz Dual-frequency radar altimeter operating in Ku and S See section bands.
