Abstract
This work presents the characterization of aerosols during a special episode of long-range transported biomass burning particles from Canadian forest fires. This event was detected at the EARLINET Granada station (37.16° N, 3.61° W, 680 m asl) from 11ᵗʰ to 17ᵗʰ July 2013, and also over other EARLINET stations. Different techniques, covering active/passive and ground based/satellite ones, have been used. In particular, the study has involved processing of both Raman and elastic lidar signals and sun-photometer AERONET data. Furthermore, modeling tools as HYSPLIT, NAAPS and BSC-DREAM8b have been used to understand the synoptic behavior of the aerosol plumes. The results highlight the presence of a multilayered structure showing large backscatter-related Angstrom Exponent (around 2) and very low particle linear depolarization (less than 0.04) at layers around 5-6 km (asl) which means considerably small and spherical particles. During the strongest period, on 14ᵗʰ July, aerosol backscatter values up to 2.9×10ˉ⁶ (m sr) ˉ¹ at 532 nm were detected in this layer.
