A) First, for the sake of clarity, we point out a mistake on page 2042 line 4: the unit of alpha is 1/km, not km (this originates from the EGU Production Office). (B) Response to both referees concerning the part of the spectrum As will be noted in the final revised version we focus on the visual part of the spectrum, according to DeMajistre et al. (1995) and Trentmann et al. (2003); important absorbers here are for example O3 and NO3. 550 nm is representative for refraction in this range.

For even smaller wavelengths the portion of the diffusive part of the radiation field increases in the lower stratosphere, and the refractive effects become less important. (C) Response to both referees concerning the extension of the solar disc S1186
