Suggestions for revision or reasons for rejection

The paper presents tests of SW flux calculations in a NWP model. Compared to the initial version the paper has been improved considerably.
One of my major concerns was, that the setup for the reference model (DISORT in the framework of libradtran) was not described, the necessary descriptions have now been added.
The other major concern was about the methodology, I suggested to compare the conversion from microphysical to optical properties and the radiative transfer solvers separately. The authors have now made clear that this is not possible for one of the schemes (hlradia) they compare, and for the other they made separate comparisons and provide results as a supplement.
As presented now, the reader understands the methodology and also the results, i.e. the performance of SW radiation schemes in different conditions. Therefore I recommend to publish the paper technical corrections (see below).

Abstract:

"blue differences" -> What does this term mean in this context, when you look at integrated irradiances, how can the difference have a color?

Introduction:

p.1, right column: "... could by parameterized ..." by -> be

p.1, right column, bottom: The 14 references in the bracket should be moved into the sentence before to clarify, what they are related to.

p.3, Sec 2.1: "... was run for the full SW spectrum of the Kato et al. correlated-k algorithm with absorption ... " -> "was run for the full SW sprectrum using the Kato et al. Correlated-k parameterization which includes absorption ..."

p5: "The primary reason for this decrease (in global radiation) is pressure broadening of the water vapor absorption lines." -> Is this really the reason? Does the line width matter when you integrate over the full spectrum? I don't see why the line broadening should affect the integrated results.

p.14: "In the DISORT version that is currently available in libRadtran the assumption of Lambertian surface reflection is also made" -> This is not true, in libRadtran several BRDFs are available for DISORT.
