We show that the solution of the radiative transfer equation (RTE) through a line of sight that pierces several times two alternate atmospheres can be obtained...

Techniques involved in measurements of solar magnetic field are based on the observation and interpretation of the polarization signal in suitable Fraunhofer...

The "line ratio method" (Stenflo, 1973) has been extensively used in the past to carry out measurements of the magnetic field strength in spatially unresolved...

Both linear and nonlinear analysis are used to gain a better understanding of the effects of multi-dimensional transfer of energy by radiation in spatially...

We combine a number of powerful mathematical techniques to produce an effective method for treating multidimensional radiative transfer problems in complex...
