According to previous investigations, sea foam is a major variable in the accurate determination of aerosol turbidity over the oceans with remote-sensing systems. As a result, tests have been conducted to measure sea foam reflectance at wavelengths from 0.55 &mgr;m to 2.8 &mgr;m. Data from the tests offer an improved knowledge of the effects of sea foam on radiation upwelled from the ocean surface at near-infrared wavelengths. Application of the new data suggests potential for a 40 percent improvement in signal to noise characteristics of aerosol measurements over the oceans if a 1.56 &mgr;m waveband is used instead of 0.75 &mgr;m.
