Atmospheric monitoring stations arebeing developed in Argentina. The most important targets are volcanic ashes,desert aerosols in particular Patagonian dust and biomass burning aerosols. Sixstations deployed in the Patagonian Region and Buenos Aires have lidar systems,sun photometers integrated to the AERONET/NASA monitoring network, in situ opticalparticle analyzers, four solar radiation sensors (pyranometer, UVA, UVB andGUV), and meteorological equipment. The stations are in the main internationalairports of the Regions (San Carlos de Bariloche, Comodoro Rivadavia, Neuquén,Rio Gallegos) and in Buenos Aires (Aeroparque Jorge Newbery and atCEILAP/CITEDEF). CEILAP and the National Institute of Environmental Studies (NIES)at Tsukuba, Japan developed the first iodine cell based high spectralresolution lidar (HSRL) in Argentina to add in the lidar network. We upgradedthe standard CEILAP multi-wavelength Raman lidar adding the laser frequencytuning system and the 532 iodine-filtered channel at the reception to built theHSRL. HSRL will provide daytime and nighttime direct observation of the aerosoland cloud optical properties (backscatter and extinction) without thepre-assumption of the lidar ratio. This work shows the design and constructionof the first Argentinean HSRL. We also show the first lidar observations donein the country with this kind of lidar.
