Resumo
To continue the effort in understanding the role of aerosol particles on continental scale, the Latin
American Lidar Network (LALINET) [Guerrero-Rascado et al., 2014] will spread its activities to the North-eastern
part of South America in the near future. A new LALINET station will be deployed at Natal (Rio Grande do Norte,
Brazil, 5.84º S, 35.20º W) with the aim of characterizing the transcontinental transport of aerosol particles from
Africa to South America, mainly Saharan dust and biomass burning, before their potential contamination with local
particles. This study is conceived as a preliminary characterization on the atmosphere over Natal based on
meteorological features including air mass clustering. On one hand, this work will allow to identify periods with the
largest frequency of Saharan dust outbreaks and biomass burning episodes over Natal. On the other hand, it will
provide a statistically detailed characterization of meteorological conditions in this region. To this aim, GDAS
information (Global Data Assimilation System) will be the inputs in our analyses and HYSPLIT model (Hybrid
Single Particle Lagrangian Integrated Trajectory model) (version 4.9) will be used to generate daily backward
trajectories at six standardized height levels.
