Abstract

The validation of the multiresolution model of sea radiance in the infrared, developed at Onera, is investigated by comparison with measurements 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 on the 22nd of May at 5 h 59 m 50 s in the mid-wave IR (3.93–4.14 μm) band and the long-wave IR (8.19–8.96 μm) band onboard the research vessel (R/V) Atalante at a grazing observational angle. A sensitivity analysis of glitter radiance on atmospheric and aerosol profiles, as well as sea temperature and wind speed in the vicinity of the measured contextual parameters, is presented. Modeled and measured images are compared and results are delved into further by comparisons of histograms, averaged vertical and horizontal profiles. Errors in the 3.93–4.14 μm band are under those potentially due to calibration, whereas discrepancies are noticed in the 8.19–8.96 μm band, where the deepest analysis has to be performed.
