Abstract

An investigation of both time-averaged and temporal solar sea glint is presented with an emphasis on the mid-infrared and low observation angles. A model combining previous works on the time-averaged radiance is assembled. Using two different wave-slope statistics obtained from disparate slope measurements, radiance values are calculated and compared to new radiometric field measurements. There is reasonable agreement between model and measurements, and this comparison suggests which of the two wave-slope statistics is superior. The temporal properties of sea glint, while lacking sufficient modeling, have been investigated through the measurement of power spectral densities and are found to fit the standard Markovian form. Correlation times derived from power spectra are reported and these values are compared to theoretical predictions and other measured correlation times derived from dissimilar experiments.
