Study on the effects of some factors that affect sea surface emissivity retrievals

The first aim of this article is to study the impact of some factors (effective wavelength, temperature, and aerial average emission angle) on sea surface emissivity (SSE) retrievals. It is well known that SSE is weakly influenced by these factors when we consider that each one of them acts independently from the others. However, taking them together, these factors are highly significant. The calculation of SSE including these factors has clearly brought out a high level of concordance between a theoretical model and in situ measurements for a wavelength of 11.0 µm especially at observation angles of 55° and 65° for wind speeds of 5 and 10 m s^?1. Wavelengths 8.7 and 12.0 µm also show, in most cases, a near to 0.000 or a negligible negative bias for an observation angle up to 55°. At wavelength 12 µm, the viewing angle of 65° seems to be questionable due to some inconsistencies and element of physics not well determined in practical terms.
