Abstract

Sea surface temperature measurements are reported using a high resolution spectroradiometer covering the longwave and midwave infrared regions viewing upwelling and down welling radiance. Measurements were collected on two different piers, one over the Atlantic Ocean (Duck, North Carolina) and the other over the Chesapeake Bay (Solomons, Maryland). The ocean salinity was 35‰ and the bay salinity was 15‰. Multiple viewing angles were examined. A method for removing reflected sky light at different angles is described. Also, a seawater emissivity model is described and applied in the data analysis. The goal is to find an optimal infrared filter pass band and viewing angle for accurate ocean surface pyrometry.
