Workspace Method CloudboxGetIncoming
Description
Calculates incoming radiation field of the cloudbox by repeated radiative transfer calculations. The method performs monochromatic pencil beam calculations for all grid positions on the cloudbox boundary, and all directions given by scattering angle grids (*scat_za/aa_grid*). Found radiances are stored in *scat_i_p/lat/lon* which can be used as boundary conditions when scattering inside the cloud box is solved by the DOIT method. Can only handle iy_unit=1 (intensity in terms of radiances). Other output units need to be derived by unit conversion later on (e.g. after yCalc).
