General comments

The authors present a case where a smoke plume was combined with clouds and produced a very strong radiative impact. Such studies are useful to understand the complex interactions between aerosols, clouds, and solar radiation. The manuscript is well written and only a few minor corrections are needed prior to its publication.

Specific comments

Adding a small paragraph relative to the direct radiative effects of BB aerosols in the introduction would be useful. Some potential references are the following.

• The impact of biomass burning aerosols on radiation over the Amazon has been discussed in Liu et al.

• The direct radiative effects of biomass burning aerosols have been also discussed in:

Section 2.4:

• More discussion relative to the setup of libRadtran is needed. For example, what was the used atmospheric profile? What was the used aerosol profile? LibRadtran is a package of models. What model was used? UVSPEC? Dis the authors consider a plane parallel or a pseudospherical atmosphere?
• Regarding cloudSat. What is the spatiotemporal resolution of the used products? How representative is the cloudSat information for cloudiness for the measurement locations?
