Source/sensor: National Data Buoy Center (NDBC), Geosat Altimeter

Coverage: 1986-1988, global

Abstract: The data product "Geosat altimeter geophysical parameters colocated with NOAA/NDBC buoy data" is an oceanographic data set. The data cover three years (1986-1988) and are located at data points determined by buoy locations in the North Atlantic and North Pacific Oceans. The data consist of selected Geosat altimeter measurements collocated with measurements from 22 buoys at fixed locations. Measurements derived from Geosat consist of the radar cross section, wind speed based on the algorithm by Brown (1981), and significant wave height. Measurements from the buoys consist of wave spectra, significant wave height, wave period, wind speed, sea and air temperatures and atmospheric pressure. The data consist of three 2-dimensional arrays. The Geosat data is collocated with the buoys in time and space. The maximum distance between a satellite footprint and a buoy is 0.5 degrees longitude. The time difference between a satellite overflight and a buoy data is less than one hour. The collocated data sets were compiled in 1990-1991 by Roman Glazman and Stuart Pilorz at the Jet Propulsion Laboratory, California Institute of Technology. The data is available via FTP or on magnetic tape.
