In the context of the climatic change of the planet, those research works that throw light on global warming are of great interest. That is the case of the studies on atmospheric aerosol, a suspension of solid or liquid particles on a gaseous environment that can contribute to the warming or cooling of the atmosphere.
Juan Luis Guerrero Rascado developed his doctoral thesis "Lidar Technique for atmospheric characterization by elastic and Raman dispersion" precisely in this research line, supervised by the Professor of the University of Granada, Lucas Alados Arboledas, director of the Group of Atmospheric Physics of the Andalusian Centre for Environmental Studies, CEAMA.
"The interest of studying the atmospheric aerosol resides in the fact that these particles influence enormously the radioactive balance of Earth, so that they can modify it and, according to the effects, there can be an atmospheric warming or cooling", says Guerrero Rascado.
Use and fine tuning of the LIDAR technique
According to Professor Alados, "the implementation of the Lidar technique is much more useful than the traditional techniques used in similar studies, as it permits us to get to know the vertical distribution of atmospheric aerosol, in which levels, in which quantity and the characteristics of such aerosol in every moment".
This technique is very similar to a radar, says the researcher, "as it consists in emitting an electromagnetic radiation, in this case laser light, which propagates in the atmosphere, interacts with the particles in suspension and afterwards, collects the radiation returned to the instrument to study from that received sign the features and the position of particles".
