Abstract : The GEOSAT satellite, to be launched in FY-84, will carry a microwave altimeter. NORDA has responsibility for implementing an operational demonstration at Fleet Numerical Oceanography Center (FNOC) in which oceanographic products utilizing information obtained from the altimeter are the result. Substantial preparation will be required. This note outlines the current status of available processing algorithms. Existing software that was used for SEASAT forms a starting point; that software and its limitations are reviewed. The SEASAT software as used did not take advantage of (or test) its full design capabilities, primarily because of the shortness of the mission and because certain information was unavailable. Current studies that build on newer developments in the interpretation of altimeter data are also described, along with a summary of background material. Some of the new studies are directed specifically toward the detection and monitoring of mesoscale features, which will be a goal of the operational demonstration and which was not a part of the routine SEASAT processing. The results of the ongoing studies will clarify the scope of the required algorithm development effort. (Author)
