Clear-sky radiance field of a plane parallel atmosphere.

The method assumes a 1D flat planet. Radiances along each direction given by za_grid are calculated using ppathPlaneParallel() and iyEmissionStandard().

Surface properties are defined by iy_surface_agenda, i.e. there is no restriction to e.g. specular surfaces.

Note that the variable ppath_lmax is considered, and that it can be critical for the accuracy for zenith angles close to 90 degrees. That is, using ppath_lmax=-1 is not recommended for this function.

Information on transmittance is also provided by the GOUT trans_field. For up-welling radiation (scat_za > 90), this variable holds the transmittance to space, for considered position and propagation direction. For down-welling radiation, trans_field holds instead the transmittance down to the surface.
