Abstract : Remote sensing data was measured over Tokyo Bay on November 24, 1981, which was a clear day. An aircraft with an MSS on board was used to collect the data (at an altitude of 4,000 m- about 12,000 feet). In addition, air-truth data was acquired at the seashore, on the sea's surface and at the altitude of the aircraft in flight. From these air-truth data, we evaluated the spectral 'path radiance' quantity and rid the apparent remote sensing data (MSS data) of atmospheric influences. This means that the quantity of spectral radiance at the sea's surface could be measured without the use of data from various altitude, vertical or sea's surface measurements.
