Resumen:
As part of environmental studies of the southern atmosphere, the CEILAP Lidar Division in collaboration with the
Service dAèronomie has developed a mobile differential absorption lidar capable of making precise and accurate
measurements of the stratospheric ozone. The XeCl excimer laser emission at 308 nm is used as absorbed line in the
DIAL technique and an Nd-YAG laser 355 nm third harmonic is employed as a reference wavelength. Six detected
channels are used for stratospheric ozone retrieval, four of them in the high and low energy of the elastically
backscattered signal of the emitted wavelengths and two corresponding to the first Stokes nitrogen Raman of the emitted
wavelengths. Tropospheric Water Vapor profiles using Raman channels and Aerosol Backscatter profiles are also
obtained. In this paper we present a detailed description of the instrument, a discussion of data analysis and the results
of the first lidar-satellite inter-comparison of stratospheric ozone profiles measured with this instrument. We also
present a description of the SOLAR campaign that will be held in the 2005 southern winter-spring period in Río
Gallegos (51º 55S, 69º 14W) with the objective of studying the ozone layer when the polar vortex crosses over the
continental part of Argentina. This campaign will be supported by JICA (Japan International Cooperation Agency).
