Resumo
Saharan mineral dust can affect the environment and climatic processes from the Western Africa,
Europe and the Eastern region of Americas due the large carrying processes of dust aerosol. This type of aerosol can
interact with the incoming energy from the Sun and alter radiation budget of the Earth-atmosphere system. Dust
particles can also change the cloud lifetime and albedo; they can induce precipitation and indirectly influence the
convective clouds height. Several studies have been conducted to understanding the physical and optical properties
of dust particles, using systems onboard satellites, airborne or ground-based instruments. However, most of the
studies were focused on African, European or North America regions. In order to fill the scientific knowledge gap
in the South America region it has been developed a new lidar system to study the transcontinental transportation of
dust aerosols from Sahara region to South America. The project has as objectives monitoring the dust aerosols
transportation seasonality, their vertical distributions in the atmosphere, their physical and optical properties and
their influences on the radiative budget. For this task, a four-channel ground based lidar for aerosol profiling,
including polarization, is being deployed at the city of Natal, in the North-Northeast region of Brazil. In this study,
we present a review of the project current instrumental status, instrument technical specification, the potential results
to be obtained and the entire performance test to be done in order to introduce the new lidar system into Latin
American Network LALINET according to procedures developed by Guerrero-Rascado et al 2014.
