The South-Patagonian region in South America is the southernmost habitable area in the world, and the inhabitant of this region directly suffers the influence of volcanic ashes spread from the Andes volcanoes that cause serious damages on agriculture, live stocks, forestry, tourism, and daily life near the volcanoes and make traffic jams of airlines over much larger area.In the period 2013-2018, Argentina, Chile and Japan run the SAVER-Net, South American Environmental Risk Management Network Project. In the frame of it, a ground based remote sensing network was developed, with different kind of instruments, like aerosols lidars, solar photometers and radiometers and particle counter that offer and ideal set of instruments to monitor the ash remobilization in the Patagonia region.The SAVER-Net network counts with of seven LIDAR systems, as independent measurement nodes, strategically emplaced in different locations of the country, to measure a variety of aerosol and atmospheric parameters. Five of them are installed at the airports of Río Gallegos, Comodoro Rivadavia, Neuquén, San Carlos de Bariloche and Aeroparque (SMN). The remaining two lidars are located at North part of the country, in the Observatories of Pilar, Córdoba and Las Talitas, Tucumán. The products obtained from the LIDAR network provide environmental sensitive information.In this work, the instrumental capabilities of SAVER-Net network will be described and a couple of different events of ash remobilization and dust transport will be presented as an example of ground based monitoring capabilities in Argentina.
