Comparison between satellite image advective velocities, dynamic topography, and surface drifter trajectories

Authors


Abstract

Recently, many investigators [Kelly, 1983, 1985; LaViolette, 1984; Vastano and Borders, 1984; Vastano and Reid, 19851 have studied the problem of computing surface velocities from high-resolution infrared satellite images of sea surface temperature (SST) patterns. The frequent synoptic coverage of large ocean areas by National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites, carrying the Advanced Very High Resolution Radiometer (AVHRR), motivates oceanographers to better utilize these data for studies of surface circulation variability.
