NettetAround the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere. Above this lies the sun’s thin atmosphere, which is made up of the chromosphere and the corona.

NettetFoam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative … NettetIn a radiation zone, energy is transported by radiation and conduction . Stellar convection consists of mass movement of plasma within the star which usually forms a circular convection current with the heated plasma ascending and the cooled plasma descending.
