                         the Amazon rainforest canopy, but their vertical profile and 
                         seasonality is currently unknown. In this study, the 
                         stratification of coarse and giant PBA >5 mu m were analyzed from 
                         the canopy to 300 m height at the Amazon Tall Tower Observatory in 
                         Brazil during the wet and dry seasons. We show that >2/3 of the 
                         coarse PBA were canopy debris, fungal spores commonly found on 
                         decaying matter were second most abundant (ranging from 15 to 
                         41\%), followed by pollens (up to 5\%). The atmospheric 
                         roughness layer right above the canopy had the greatest giant PBA 
                         abundance. Measurements over 5 years showed an increased abundance 
                         of PBA during a low-rainfall period. Giant particles, such as 
                         pollen, are reduced at 300 m, suggesting their limited dispersal. 
                         These results give insights into the giant PBA emissions of this 
                         tropical rainforest, and present a major step in understanding the 
                         type of emitted particles and their vertical distribution.",
