Webeffect of sea foam in a future WindSat forward model, we started work on modeling the foam emissivity, e f,at frequencies from 6.8 GHz to 37 GHz. Since foam influences salinity measurements [Font et al., 2003; Camps et al., 2005], we also consider the frequency of 1.4 GHz. [3] The quantities necessary for computing e f are attenu- WebThe emissivity for oceans varies because of wind-induced foam and surface roughness (see Fig. 7.25). Within the field of view of the microwave instrument, about 25–100 km resolution, the effect of emissivity is relatively small and can be taken into account by empirical approaches as shown above.
