For quantitative analysis of ocean color from high altitude or orbital platforms, it is necessary to correct the apparent signal for losses and gains due to atmospheric scattering and absorption. However, comprehensive knowledge of the transmittance and path radiance of the atmosphere over the oceans necessary for these corrections is limited. In order to support studies of ocean color utilizing the Coastal Zone Color Scanner aboard Nimbus-7, measurements of atmospheric transmittance and path radiance have been made at a number of maritime stations. The measurements were made at ten wavelengths between 400 and 750 nanometers and have provided new insight into atmospheric scattering and absorption over the ocean. A description of the solar transmissometer used in the program is provided along with some of the measurements. Comparisons of the measurements with predictions from the atmospheric transmittance program LOWTRAN have been made and are discussed. The significance of the measurements to the remote sensing of the ocean color is also reviewed.
