Description:
Two lidar systems, an aerosol lidar and an O$_3 DIfferential Absorption
Lidar (DIAL), have been routinely operated at the same site (L'Aquila,
Italy; 42°N, 13°E) since August 1991. The multiwavelength analysis of
the lidar signals allows to retrieve parameters related to equivalent
aerosol size distributions and their optical properties. These are
needed to correct the ozone DIAL profiles from the disturbance
introduced by the stratospheric volcanic aerosols. The method and the
confidence of the retrieved ozone profiles are discussed in a companion
paper. Here we present the whole measurement series of ozone and
backscattering ratio profiles during the period from August 1991 to
December 1992. In addition, for some observations, the mode radius
and the dispersion of the representative aerosol size distribution are
reported. The time evolutions of aerosol surface area density and mass
mixing ratio are also discussed within the uncertainties of the retrieval
algorithm.
