Accuracy of Direct Measurement of Mean Surface Water Velocity of the Kuroshio Using Multi-Temporal NOAA-6 Imageries,
REMOTE SENSING TECHNOLOGY CENTER OF JAPAN TOKYO
This paper discusses a method of directly measuring the mean surface velocity of the Kuroshio Current using multi-temporal NOAA-6AVHRR imageries and investigating the accuracy of the measurements. The data from Channel 4 of the NOAA-6AVHRR show the water temperature of the seas surface some special features such as a vortex, the so called Sea Mark, can be clearly recognized along the line formed by the meeting of different water masses. The NOAA-6 imageries can be observed about every 12 hours two successive imageries can give use the drifting distance during that period. It distance is divided by time, the result is corresponding water velocity. The accurancy of current standard deviation. The velocity distribution map of the entire sea zone around Japans bow-shaped islands was made by this means, namely, from time serial NOAA imageries and was then compared with the most recently published map of oceanic current by the Maritime Safety Board of Japan.
