Abstract

The validation of the sea surface infrared optical properties multiresolution model developed at ONERA is investigated by comparison with measurements. The images were obtained during the MIRAMER campaign that took place in May 2008 in the Mediterranean Sea. The sea radiance model and optical properties are expressed and the experimental setup of the campaign is briefly presented. We focus on solar glint measurements collected the 22 ^th of May at 5 h 59mn 50s in the MWIR bandwidth on-board the R/V ATALANTE at grazing observational angle. A sensitivity analysis of glitter radiance on atmospheric and aerosol profiles in the vicinity of the measured contextual parameters is presented. Modelled and measured images are compared and results are delved further by comparisons of histograms, averaged vertical and horizontal profiles. Errors are under those potentially due to calibration. Finally, a sensitivity analysis upon uncertainties on contextual parameters involved in sea radiance computation is made.
