Tesis Univ. Granada.Abstract
The observation and study of the Earth’s atmosphere have
become of increasing concern because of the interest on
weather prediction, air quality and climate change. Among all
the atmospheric components and processes related to those
topics, atmospheric aerosol particles (defined as solid and/or
liquid particles suspended on the atmospheric air, excluding
clouds) and the dynamic and turbulent properties of the
atmospheric boundary layer (ABL, the lowermost part of the
atmosphere, that is directly influenced by the Earth’s surface)
represent two of the most active research fields due to the lack
of knowledge about the uncertainties of their effects. For Granada and Rzecin sites, where the available
databases were of two years and four months, respectively, we
have been able to perform a statistical analysis of the main
turbulent sources within those analyzed periods, with temporal
(for each hour of the day) and height resolution. A seasonal
distinction has been done only for Granada. Both sites show a
clear convective activity during daytime at altitudes increasing
with time, and a significant wind-shear driven turbulence
during nighttime, in special in Rzecin. We have also found at
both sites an important contribution of nocturnal turbulence
with unknown sources (labelled as ‘intermittent’) although in
Rzecin it is mostly concentrated around 600 m a.g.l., while in
Granada it is present at all heights.
