Short summary
A widespread and persistent smoke layer was observed in the Amazon region during the biomass burning season, spanning a distance of 2200 km and a period of 14 days. The larger smoke content was typically found in elevated layers, from 1–1.5 km to 4–6 km. Measurements have been compared to model predictions, and the latter were able to reproduce the general features of the smoke layer, but with some differences which are analysed and described in the paper.
