Aerosols vary rapidly in time and space, but in particular information
of the vertical distribution was lacking before the advent of lidar
systems. Depending on the system's complexity, lidar data can be
evaluated with respect to aerosol backscatter and extinction
coefficients at several wavelengths; and based on this information,
estimates of the size distribution and the refractive index of the
particles are
possible. Furthermore, spherical and non-spherical particles can be
distinguished by means of depolarization measurements.
The benefit of lidar data depends on the sampling strategies and data
quality. That means that networks of lidar systems that have undergone
strict quality control protocols are most promising.
In this session most recent results from the EARLINET, in particular
from beyond the 2000-2002 period, and other lidar networks shall be
presented but also developments that are underway or should be
implemented in the future. Scientific topics, where the contribution of
lidar networks is of special advantage, shall be covered, e.g.,
characterization of Saharan dust, processes in the boundary layer, or
investigations of long range transport. Furthermore, the session should
include the update of quality control procedures, retrieval methods and
instrument technology. Finally, contributions to the upcoming CALIPSO
validation experiments shall be discussed and strategies for data
assimilation.
